Research On Overhaul Technology Of Asphalt Concrete Pavement In Changshou To Liangping Expressway

With the gradual slow China’s rapid economic development and highway construction period,a steady increase in car ownership in China, and the heavy traffic presents increasing trend to bring enormous pressure has built highways, highway asphalt pavement can not appeared to avoid all kinds of diseases. It must take reasonable steps to promptly deal with all kinds of diseases road appeared to make the road to maintain a high service capacity,in the pre-reach targets, the road overhaul technology is particularly important.Firstly, for the current mountain freeway asphalt pavement common diseases are classified and investigations, including different types of diseases, weather conditions, traffic surveys and analyzes the causes of the disease; for different pavement disease, according to research carried out to co-ordinate domestic and disposal technologies Diseases From the cracks,water damage, rutting,subsidence and other diseases, this paper proposes the prevention and Treatment Measures appropriate.Second, the combination of disease investigation and road disposal technology, research and longevity to the Pacific section of asphalt pavement overhaul project as the basis, the overall program design overhaul from the road, the road Jia Lu program, micro-surfacing program, Pavement Distress partial turn sleeve design, old asphalt change reasonable recycling, deck waterproofing adhesive layer, anti-anti-material aspects of the transition period setting and put forward a peaceful section of asphalt pavement longevity to improve the program.Finally, a section of pavement longevity to overhaul the Pacific with the ratio test, from the micro-surfacing, waterproof adhesive layer, a strong wind had fiberglass, gravel and recycled asphalt mixture made of asphalt pavement to improve trial design and technical specifications, including glass fiber-reinforced sealing layer design highlights and innovation-oriented overhaul of the design.Highway asphalt pavement Leung raised by this study to improve the technical and overhaul solutions to achieve standardization of highway asphalt pavement maintenance work, scientific and efficient provision of technical support requirements,thereby helping to improve the performance of the highway and age.
