Study On The In-place Hot Recycling Technology Of Asphalt Pavement In Jilin Province

Asphalt pavement has a smooth surface, solid, ride comfort, good wear resistance, the open fasttransportation, maintenance and repair is simple and suitable for phased construction, etc., has been widelyused in China’s high-grade highways. However, with the aging of asphalt and traffic load, resulting inasphalt pavement gradually produce a variety of diseases, reducing road capacity. Hot in-place recyclingtechnology is gradually introduced into China from the late1990s, a new technology, the current domesticAsphalt Pavement thermal regeneration of the total area of nearly4million square meters of roadmaintenance and reconstruction of one of the methods.From the asphalt concrete pavement recycling technology development and application status, the firstexpounded the necessity of the development of asphalt concrete recycling technology, pointed out that theapplicable conditions and the advantages and disadvantages of the problems faced today by the materials ofthe old road test analysis. Regenerant regeneration performance, new asphalt recycling agent combinationof performance and a new set of material dosage various combinations of a large number of tests to analyzecomparative studies, preferably comparison to determine asphalt mixture ratio. Mixture low temperaturecrack resistance, high temperature stability and water stability test analysis, testing the performance of hotasphalt recycling material. By analyzing the test section construction machinery, personnel with thesummary of the construction process, pointing out that the check control key link in the constructionprocess, the content and frequency of inspection and acceptance, and in accordance with engineeringexamples of its economic and social benefits.
