Asphalt Pavement Repairing Technology And Engineering Application

With plenty of high-grade highway construction, asphalt pavement has been more andmore used. From the use of built high-grade highway, early damages have appeared in asphaltpavement of newly built high-grade highways. Much highway constraction investment will beinduced and traffic capability and service quality will be improved, if early damages can beresolved. So, it is significant to make maintenance and repair to the early damages of asphaltpavement. To the asphalt pavement of severe damages, rapid repair method shoult be adoptedto make sure the shortest repair time and to prevent the damages to rurning worse.As people become more and more prosperous life, traffic volume will continue toincrease. Increasing road traffic, the road surface is facing a severe test, many roads wereshowing different degrees of damage. While the asphalt pavement for road from country tocity road, road, from the three stage highway to freeway, are commonly used. But because theasphalt concrete material itself differences, as well as the design, construction andmaintenance level and the influence of external environment, the asphalt pavement cracks,loose, often subsidence, cracking, rutting, bleeding, pits and other diseases. These defectsappear serious influence driving speed, driving safety, shorten the service life of asphaltpavement, the pavement caused by shortening.This paper mainly studies the highway asphalt pavement repairing technology andpractical application, and examples of engineering as the basis, through the analysis of disease,disease detection and evaluation of asphalt pavement repair technology, and its application inengineering. And according to the present our country actual asphalt pavement repairtechnology, explore suitable for China’s national conditions of preventive maintenance ofasphalt pavement maintenance concept, new technology and new materials. Through theactual project application, to verify the results is correct, feasible and practical, can be ourcountry asphalt pavement detection, evaluation and repair maintenance, provide a reference...
