Research On Rutting Control Technology Of Repair And Maintenance Of Asphalt Pavement

Traffic as henan province about their location, highway construction has always been in the forefront of the various investment construction, successive years of massive investment, the highway in henan province has maintained the national highway mileage the location of the first, by the end of2012to5800km at the same time, the national economy high speed development of traffic is growing rapidly, increasing vehicle tonnage overload is serious, the problem such as traffic channelization, and global climate problems lead to continuous high temperature summer weather phenomenon such as sustained growth makes asphalt pavement faces a severe test, rutting has quickly become one of the most serious asphalt surface, is also very common damage form this topic closely integrated entity project, through the analysis of system study of the causes of rutting damage.Closely with the subject entity engineering, produced by system analysis of rutting causes harm, the rutting causes and types, and puts forward the control and prevention measures of asphalt pavement rutting. According to the analysis of rutting and temperature and critical temperature is proposed to track indicators for the control design of pavement asphalt and asphalt mixture, improve the performance of asphalt mixture, high temperature rutting ability enhancement at. Traffic management is an important measure to reduce the overload of rut, governance phenomenon of overload control is an important part of road damage.The outcome of the technology put forward concrete and practical measures for the rutting problem, taking into account the other road performance, high-speed road repair in the Ta River played a very good role, repair the pavement performance. Practice has proved, this technology can effectively improve the rutting, pavement performance and economic benefit, and provides the reliable basis for the design of asphalt pavement construction and maintenance, repair, which has great significance to ensure the project quality, worthy of promotion.
