About Infrared Asphalt Repair
Due to its ease of use, durability, and cost-effectiveness, asphalt has been a popular paving material for many decades. Asphalt problems can happen at anytime, whether you live in a residential or commercial property. You might need a solid pavement management program to address cracking, potholes, and exposed utility hole covers.
Your asphalt will last longer if you have a good pavement maintenance strategy in place. When your asphalt deteriorates, the infrared repair service is an efficient and cost-effective option.
What is Infrared Asphalt Repair?
he infrared repair process is something you've likely seen in action. This popular temporary paving option is often employed in business and residential settings.
Infrared asphalt repairs use infrared light to heat asphalt pavement until it becomes soft. It allows for the quick removal of asphalt that has failed. Next, the asphalt is mixed with new or recycled asphalt. A crew of two to three skilled craftsmen recycles the asphalt using one truck.
This method is becoming more popular for asphalt repairs because it is easy and environmentally friendly. There is also minimal downtime once the process is complete. Using this technology, you can fix problems like potholes, bumps in the road, and uneven surfaces in your driveway.
Infrared asphalt repairs are not the best solution for all asphalt problems. This process is much faster than traditional removal and replacement, so there's little disruption for you and your tenants. Infrared repairs are less costly than conventional repairs to potholes because of the savings. However, it is preferred by paving professionals for specific asphalt issues that you can fix over time.
One of the most significant benefits of using this method is the speed with which your pavement may be reopened to traffic when repairs are completed.
How Does Infrared Repair Work?
With infrared technology, damaged asphalt may be repaired by heating and replenishing the material before being blended with fresh asphalt and compacted. It is a step-by-step guide to the process of repairing asphalt.
- You must sweep the area clean of all debris and dry it thoroughly. It will ensure that the infrared repairs do not block the asphalt surface.
- The asphalt is heated to 325°F for approximately 5–10 minutes by an infrared heater placed over the area. This healing time can vary depending on the extent of the damage, the season, and the aggregate used.
- After heating, you can rake the repaired area, removing any loose or failed aggregate.
- Due to oxidization and age, the remaining aggregate is treated with a rejuvenator to replenish lost oils.
- Asphalt is mixed and added to new asphalt. It ensures that asphalt is graded at the correct level.
- A multi-ton vibratory roller or plate is used to condense the material after it has been combined, resulting in a smooth patch.
You may compact an asphalt patch without fear of it shrinking over time since the infrared system does not disturb the sub-base. The new patch is hardly undetectable until you look closely at the disagreeing color. On a bigger scale, the infrared method works just as effectively on utility cuts that span a whole road.
What Are the Benefits of Infrared Repair?
Infrared asphalt repair has many benefits. BaraCo Paving can help you reap the full benefits of infrared asphalt repairs. These benefits include:
Traditional asphalt resurfacing takes longer to repair. A typical 5' x 7' infrared repair takes about 20 minutes. The road can also be reopened immediately upon completion.
Due to the patch's thermal bonding with the surrounding surface, it eliminates the need to "tack-coat" the edges. There is no cold seam for water to penetrate and cause joint failure.
You can do infrared asphalt repairs with recycled asphalt, which reduces the need to purchase new asphalt materials. It means that there are fewer waste and handling costs.
The use of infrared technology can help a business save thousands of dollars. Infrared installation costs are competitive with traditional cold asphalt repairs.
Fewer Traffic Interruptions.
You can drive on the patch almost immediately. It usually takes 20-30 minutes for the surface to be ready for traffic. You can then use the road or paved surface again as soon as the repairs are complete.
Infrared rays can penetrate asphalt and allow for reclaiming. It is done without burning, scaling, or separating the asphalt from its aggregate.
What Is Infrared Asphalt Repair Used For?
Infrared asphalt repairs are a great solution, but they are not the best for all pavement problems. You can use the process to repair small areas of asphalt. It is where infrared asphalt repairs are most effective.
- Pothole and crack repair.
- Installation of speed bumps
- Handicap ramps
- Surfaces that are rough or uneven
- Paver seams
- Storm drains and maintenance holes
- High spots and bumps
- Trench repairs
How to Make Infrared Asphalt Repair a Success?
Infrared asphalt repairs can be a success if you take specific steps. These are the essential factors to ensure that your infrared asphalt repair is a success.
A minimal amount of water may evaporate during the infrared heating process. The heat and water can cause the asphalt to crack or deteriorate. For successful infrared asphalt repair, you must eliminate moisture.
Infrared asphalt repairs are difficult to do on windy days. Wind can cause infrared asphalt repairs to take longer, leading to poor results. Make sure not to repair it on a windy day.
Infrared asphalt repairs benefit from warm weather. Having a hot day encourages the healing process, which results in a smoother and more effective asphalt repair when using infrared technology.
Is it Worth It to Use Infrared Asphalt Repair?
Asphalt may survive up to twenty years if it is correctly cared for. Even if you take every precaution to maintain your asphalt driveway in good condition, problems might still develop. BaraCo Paving is here for you. We recommend the best option for your asphalt pavement care and maintenance. Contact us now to learn more about infrared asphalt repair.
About University, FL
The original Latin word universitas refers in general to "a number of persons associated into one body, a society, company, community, guild, corporation, etc". At the time of the emergence of urban town life and medieval guilds, specialized "associations of students and teachers with collective legal rights usually guaranteed by charters issued by princes, prelates, or the towns in which they were located" came to be denominated by this general term. Like other guilds, they were self-regulating and determined the qualifications of their members.
In modern usage the word has come to mean "An institution of higher education offering tuition in mainly non-vocational subjects and typically having the power to confer degrees," with the earlier emphasis on its corporate organization considered as applying historically to Medieval universities.
The original Latin word referred to degree-awarding institutions of learning in Western and Central Europe, where this form of legal organisation was prevalent and from where the institution spread around the world.
An important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the University of Bologna, which adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of "academic freedom". This is now widely recognised internationally – on 18 September 1988, 430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bologna's foundation. The number of universities signing the Magna Charta Universitatum continues to grow, drawing from all parts of the world.
An early institution often called a university is the Harran University, founded in the late 8th century. Scholars occasionally call the University of al-Qarawiyyin (name given in 1963), founded as a mosque by Fatima al-Fihri in 859, a university, although Jacques Verger writes that this is done out of scholarly convenience. Several scholars consider that al-Qarawiyyin was founded and run as a madrasa until after World War II. They date the transformation of the madrasa of al-Qarawiyyin into a university to its modern reorganization in 1963. In the wake of these reforms, al-Qarawiyyin was officially renamed "University of Al Quaraouiyine" two years later.
Some scholars, including George Makdisi, have argued that early medieval universities were influenced by the madrasas in Al-Andalus, the Emirate of Sicily, and the Middle East during the Crusades. Norman Daniel, however, views this argument as overstated. Roy Lowe and Yoshihito Yasuhara have recently drawn on the well-documented influences of scholarship from the Islamic world on the universities of Western Europe to call for a reconsideration of the development of higher education, turning away from a concern with local institutional structures to a broader consideration within a global context.
The modern university is generally regarded as a formal institution that has its origin in the Medieval Christian tradition.
European higher education took place for hundreds of years in cathedral schools or monastic schools (scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century.
In Europe, young men proceeded to university when they had completed their study of the trivium – the preparatory arts of grammar, rhetoric and dialectic or logic–and the quadrivium: arithmetic, geometry, music, and astronomy.
The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and perhaps from cathedral schools. It is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were also founded by kings (University of Naples Federico II, Charles University in Prague, Jagiellonian University in Kraków) or municipal administrations (University of Cologne, University of Erfurt). In the early medieval period, most new universities were founded from pre-existing schools, usually when these schools were deemed to have become primarily sites of higher education. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by The residence of a religious community. Pope Gregory VII was critical in promoting and regulating the concept of modern university as his 1079 Papal Decree ordered the regulated establishment of cathedral schools that transformed themselves into the first European universities.
The first universities in Europe with a form of corporate/guild structure were the University of Bologna (1088), the University of Paris (c.1150, later associated with the Sorbonne), and the University of Oxford (1167).
The University of Bologna began as a law school teaching the ius gentium or Roman law of peoples which was in demand across Europe for those defending the right of incipient nations against empire and church. Bologna's special claim to Alma Mater Studiorum is based on its autonomy, its awarding of degrees, and other structural arrangements, making it the oldest continuously operating institution independent of kings, emperors or any kind of direct religious authority.
The conventional date of 1088, or 1087 according to some, records when Irnerius commences teaching Emperor Justinian's 6th-century codification of Roman law, the Corpus Iuris Civilis, recently discovered at Pisa. Lay students arrived in the city from many lands entering into a contract to gain this knowledge, organising themselves into 'Nationes', divided between that of the Cismontanes and that of the Ultramontanes. The students "had all the power … and dominated the masters".
All over Europe rulers and city governments began to create universities to satisfy a European thirst for knowledge, and the belief that society would benefit from the scholarly expertise generated from these institutions. Princes and leaders of city governments perceived the potential benefits of having a scholarly expertise develop with the ability to address difficult problems and achieve desired ends. The emergence of humanism was essential to this understanding of the possible utility of universities as well as the revival of interest in knowledge gained from ancient Greek texts.
The recovery of Aristotle's works – more than 3000 pages of it would eventually be translated – fuelled a spirit of inquiry into natural processes that had already begun to emerge in the 12th century. Some scholars believe that these works represented one of the most important document discoveries in Western intellectual history. Richard Dales, for instance, calls the discovery of Aristotle's works "a turning point in the history of Western thought." After Aristotle re-emerged, a community of scholars, primarily communicating in Latin, accelerated the process and practice of attempting to reconcile the thoughts of Greek antiquity, and especially ideas related to understanding the natural world, with those of the church. The efforts of this "scholasticism" were focused on applying Aristotelian logic and thoughts about natural processes to biblical passages and attempting to prove the viability of those passages through reason. This became the primary mission of lecturers, and the expectation of students.
The university culture developed differently in northern Europe than it did in the south, although the northern (primarily Germany, France and Great Britain) and southern universities (primarily Italy) did have many elements in common. Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics; while Hippocrates, Galen, and Avicenna were used for medicine. Outside of these commonalities, great differences separated north and south, primarily in subject matter. Italian universities focused on law and medicine, while the northern universities focused on the arts and theology. There were distinct differences in the quality of instruction in these areas which were congruent with their focus, so scholars would travel north or south based on their interests and means. There was also a difference in the types of degrees awarded at these universities. English, French and German universities usually awarded bachelor's degrees, with the exception of degrees in theology, for which the doctorate was more common. Italian universities awarded primarily doctorates. The distinction can be attributed to the intent of the degree holder after graduation – in the north the focus tended to be on acquiring teaching positions, while in the south students often went on to professional positions. The structure of northern universities tended to be modeled after the system of faculty governance developed at the University of Paris. Southern universities tended to be patterned after the student-controlled model begun at the University of Bologna. Among the southern universities, a further distinction has been noted between those of northern Italy, which followed the pattern of Bologna as a "self-regulating, independent corporation of scholars" and those of southern Italy and Iberia, which were "founded by royal and imperial charter to serve the needs of government."
During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first European university was founded, there were 29 universities spread throughout Europe. In the 15th century, 28 new ones were created, with another 18 added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) – this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. The identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
The propagation of universities was not necessarily a steady progression, as the 17th century was rife with events that adversely affected university expansion. Many wars, and especially the Thirty Years' War, disrupted the university landscape throughout Europe at different times. War, plague, famine, regicide, and changes in religious power and structure often adversely affected the societies that provided support for universities. Internal strife within the universities themselves, such as student brawling and absentee professors, acted to destabilize these institutions as well. Universities were also reluctant to give up older curricula, and the continued reliance on the works of Aristotle defied contemporary advancements in science and the arts. This era was also affected by the rise of the nation-state. As universities increasingly came under state control, or formed under the auspices of the state, the faculty governance model (begun by the University of Paris) became more and more prominent. Although the older student-controlled universities still existed, they slowly started to move toward this structural organization. Control of universities still tended to be independent, although university leadership was increasingly appointed by the state.
Although the structural model provided by the University of Paris, where student members are controlled by faculty "masters", provided a standard for universities, the application of this model took at least three different forms. There were universities that had a system of faculties whose teaching addressed a very specific curriculum; this model tended to train specialists. There was a collegiate or tutorial model based on the system at University of Oxford where teaching and organization was decentralized and knowledge was more of a generalist nature. There were also universities that combined these models, using the collegiate model but having a centralized organization.
Early Modern universities initially continued the curriculum and research of the Middle Ages: natural philosophy, logic, medicine, theology, mathematics, astronomy, astrology, law, grammar and rhetoric. Aristotle was prevalent throughout the curriculum, while medicine also depended on Galen and Arabic scholarship. The importance of humanism for changing this state-of-affairs cannot be underestimated. Once humanist professors joined the university faculty, they began to transform the study of grammar and rhetoric through the studia humanitatis. Humanist professors focused on the ability of students to write and speak with distinction, to translate and interpret classical texts, and to live honorable lives. Other scholars within the university were affected by the humanist approaches to learning and their linguistic expertise in relation to ancient texts, as well as the ideology that advocated the ultimate importance of those texts. Professors of medicine such as Niccolò Leoniceno, Thomas Linacre and William Cop were often trained in and taught from a humanist perspective as well as translated important ancient medical texts. The critical mindset imparted by humanism was imperative for changes in universities and scholarship. For instance, Andreas Vesalius was educated in a humanist fashion before producing a translation of Galen, whose ideas he verified through his own dissections. In law, Andreas Alciatus infused the Corpus Juris with a humanist perspective, while Jacques Cujas humanist writings were paramount to his reputation as a jurist. Philipp Melanchthon cited the works of Erasmus as a highly influential guide for connecting theology back to original texts, which was important for the reform at Protestant universities. Galileo Galilei, who taught at the Universities of Pisa and Padua, and Martin Luther, who taught at the University of Wittenberg (as did Melanchthon), also had humanist training. The task of the humanists was to slowly permeate the university; to increase the humanist presence in professorships and chairs, syllabi and textbooks so that published works would demonstrate the humanistic ideal of science and scholarship.
Although the initial focus of the humanist scholars in the university was the discovery, exposition and insertion of ancient texts and languages into the university, and the ideas of those texts into society generally, their influence was ultimately quite progressive. The emergence of classical texts brought new ideas and led to a more creative university climate (as the notable list of scholars above attests to). A focus on knowledge coming from self, from the human, has a direct implication for new forms of scholarship and instruction, and was the foundation for what is commonly known as the humanities. This disposition toward knowledge manifested in not simply the translation and propagation of ancient texts, but also their adaptation and expansion. For instance, Vesalius was imperative for advocating the use of Galen, but he also invigorated this text with experimentation, disagreements and further research. The propagation of these texts, especially within the universities, was greatly aided by the emergence of the printing press and the beginning of the use of the vernacular, which allowed for the printing of relatively large texts at reasonable prices.
Examining the influence of humanism on scholars in medicine, mathematics, astronomy and physics may suggest that humanism and universities were a strong impetus for the scientific revolution. Although the connection between humanism and the scientific discovery may very well have begun within the confines of the university, the connection has been commonly perceived as having been severed by the changing nature of science during the Scientific Revolution. Historians such as Richard S. Westfall have argued that the overt traditionalism of universities inhibited attempts to re-conceptualize nature and knowledge and caused an indelible tension between universities and scientists. This resistance to changes in science may have been a significant factor in driving many scientists away from the university and toward private benefactors, usually in princely courts, and associations with newly forming scientific societies.
Other historians find incongruity in the proposition that the very place where the vast number of the scholars that influenced the scientific revolution received their education should also be the place that inhibits their research and the advancement of science. In fact, more than 80% of the European scientists between 1450 and 1650 included in the Dictionary of Scientific Biography were university trained, of which approximately 45% held university posts. It was the case that the academic foundations remaining from the Middle Ages were stable, and they did provide for an environment that fostered considerable growth and development. There was considerable reluctance on the part of universities to relinquish the symmetry and comprehensiveness provided by the Aristotelian system, which was effective as a coherent system for understanding and interpreting the world. However, university professors still utilized some autonomy, at least in the sciences, to choose epistemological foundations and methods. For instance, Melanchthon and his disciples at University of Wittenberg were instrumental for integrating Copernican mathematical constructs into astronomical debate and instruction. Another example was the short-lived but fairly rapid adoption of Cartesian epistemology and methodology in European universities, and the debates surrounding that adoption, which led to more mechanistic approaches to scientific problems as well as demonstrated an openness to change. There are many examples which belie the commonly perceived intransigence of universities. Although universities may have been slow to accept new sciences and methodologies as they emerged, when they did accept new ideas it helped to convey legitimacy and respectability, and supported the scientific changes through providing a stable environment for instruction and material resources.
Regardless of the way the tension between universities, individual scientists, and the scientific revolution itself is perceived, there was a discernible impact on the way that university education was constructed. Aristotelian epistemology provided a coherent framework not simply for knowledge and knowledge construction, but also for the training of scholars within the higher education setting. The creation of new scientific constructs during the scientific revolution, and the epistemological challenges that were inherent within this creation, initiated the idea of both the autonomy of science and the hierarchy of the disciplines. Instead of entering higher education to become a "general scholar" immersed in becoming proficient in the entire curriculum, there emerged a type of scholar that put science first and viewed it as a vocation in itself. The divergence between those focused on science and those still entrenched in the idea of a general scholar exacerbated the epistemological tensions that were already beginning to emerge.
The epistemological tensions between scientists and universities were also heightened by the economic realities of research during this time, as individual scientists, associations and universities were vying for limited resources. There was also competition from the formation of new colleges funded by private benefactors and designed to provide free education to the public, or established by local governments to provide a knowledge-hungry populace with an alternative to traditional universities. Even when universities supported new scientific endeavors, and the university provided foundational training and authority for the research and conclusions, they could not compete with the resources available through private benefactors.
By the end of the early modern period, the structure and orientation of higher education had changed in ways that are eminently recognizable for the modern context. Aristotle was no longer a force providing the epistemological and methodological focus for universities and a more mechanistic orientation was emerging. The hierarchical place of theological knowledge had for the most part been displaced and the humanities had become a fixture, and a new openness was beginning to take hold in the construction and dissemination of knowledge that were to become imperative for the formation of the modern state.
Modern universities constitute a guild or quasi-guild system. This facet of the university system did not change due to its peripheral standing in an industrialized economy; as commerce developed between towns in Europe during the Middle Ages, though other guilds stood in the way of developing commerce and therefore were eventually abolished, the scholars guild did not. According to historian Elliot Krause, "The university and scholars' guilds held onto their power over membership, training, and workplace because early capitalism was not interested in it."
By the 18th century, universities published their own research journals and by the 19th century, the German and the French university models had arisen. The German, or Humboldtian model, was conceived by Wilhelm von Humboldt and based on Friedrich Schleiermacher's liberal ideas pertaining to the importance of freedom, seminars, and laboratories in universities. The French university model involved strict discipline and control over every aspect of the university.
Until the 19th century, religion played a significant role in university curriculum; however, the role of religion in research universities decreased during that century. By the end of the 19th century, the German university model had spread around the world. Universities concentrated on science in the 19th and 20th centuries and became increasingly accessible to the masses. In the United States, the Johns Hopkins University was the first to adopt the (German) research university model and pioneered the adoption of that model by most American universities. When Johns Hopkins was founded in 1876, "nearly the entire faculty had studied in Germany." In Britain, the move from Industrial Revolution to modernity saw the arrival of new civic universities with an emphasis on science and engineering, a movement initiated in 1960 by Sir Keith Murray (chairman of the University Grants Committee) and Sir Samuel Curran, with the formation of the University of Strathclyde. The British also established universities worldwide, and higher education became available to the masses not only in Europe.
In 1963, the Robbins Report on universities in the United Kingdom concluded that such institutions should have four main "objectives essential to any properly balanced system: instruction in skills; the promotion of the general powers of the mind so as to produce not mere specialists but rather cultivated men and women; to maintain research in balance with teaching, since teaching should not be separated from the advancement of learning and the search for truth; and to transmit a common culture and common standards of citizenship."
In the early 21st century, concerns were raised over the increasing managerialisation and standardisation of universities worldwide. Neo-liberal management models have in this sense been critiqued for creating "corporate universities (where) power is transferred from faculty to managers, economic justifications dominate, and the familiar 'bottom line' eclipses pedagogical or intellectual concerns". Academics' understanding of time, pedagogical pleasure, vocation, and collegiality have been cited as possible ways of alleviating such problems.
A national university is generally a university created or run by a national state but at the same time represents a state autonomic institution which functions as a completely independent body inside of the same state. Some national universities are closely associated with national cultural, religious or political aspirations, for instance the National University of Ireland, which formed partly from the Catholic University of Ireland which was created almost immediately and specifically in answer to the non-denominational universities which had been set up in Ireland in 1850. In the years leading up to the Easter Rising, and in no small part a result of the Gaelic Romantic revivalists, the NUI collected a large amount of information on the Irish language and Irish culture. Reforms in Argentina were the result of the University Revolution of 1918 and its posterior reforms by incorporating values that sought for a more equal and laic[further explanation needed] higher education system.
Universities created by bilateral or multilateral treaties between states are intergovernmental. An example is the Academy of European Law, which offers training in European law to lawyers, judges, barristers, solicitors, in-house counsel and academics. EUCLID (Pôle Universitaire Euclide, Euclid University) is chartered as a university and umbrella organization dedicated to sustainable development in signatory countries, and the United Nations University engages in efforts to resolve the pressing global problems that are of concern to the United Nations, its peoples and member states. The European University Institute, a post-graduate university specialized in the social sciences, is officially an intergovernmental organization, set up by the member states of the European Union.
