Distress Prevention and Treatments for Reflection Cracks or Joint of New and Old Road Surface Used by Polyester Bolivia Filament Cloth

The Shanghai to Nanjing Expressway extension project used by the method of "two sides splicing widens primarily,the local separation widens".The old road is extended to eight traffic lanes in the condition of the technical standard of the original Shanghai to Nanjing Expressway is not changed.At present,in view of the fact that still did not have the design and the construction standards of the expressway extension project,the polyester Bolivia filament cloth is used in the splicing construction of the new and the old half rigid base or the joints or the cracks treated after the old bituminous pavement surface recapping,which can effectively prevent the reflection crack production and the water destruction.The analysis and research on the performance and the construction technology of polyester Bolivia filament cloth are carried out.
