Research On Asphalt Pavement Cold Reutilization Workmanship Technology

Along with the people'sconcern on environment protection and the development of thetechnology, asphalt pavement regeneration application technology has been paid more andmore attention. In the recent years, the quantity of asphalt pavement maintenance and repair inChina has gradually increased. The reconstruction of highway has also increased. It becomesseriously important to deepen systematic research about the reutilization technology of theexisting materials of asphalt pavement.Asphalt pavement cold reutilization workmanship had been applied for the National No.108 Trunk Road Fanshi-Yuanping Class II Road Reconstruction Works in Shanxi province. It isthe first case in this province. It had brought about the successful experience, satisfactory socialand economical benefits. The cold reutilization technology had also been applied for theYuncheng-Fenglindu Expressway Reconstruction Works in the Province. It shortenedconstruction time and saved cost. It had minimized affect on the expressway traffic. It is greatlyeconomical and political significant to assure that the expresswayis free open to traffic.This essay, through research about the asphalt pavement coal reutilization technologyapplication in the Shanxi province, summaries construction machinery, constructionworkmanship, construction quality control of the asphalt pavement coal reutilizationworkmanship. It highlights that the asphalt pavement in-situ cold reutilization workmanship hasmany advantages such as simple and fast construction, the best use of existing pavementmaterials, environment protection, reliable quality, very little rise of the original pavement,unnecessary for closure of highway traffic, good economical benefits, etc. The purpose is toprovide reference for cold reutilization technology application and push it forward in the roadreconstruction project and road maintenance and repair works.
