Applied Technology Study Of The Domestic Natural Shale Asphalt In The Bituminous Pavement

Of highway undertakings have developed rapidly, and has made considerable progress. At present, China’s highway mileage has reached40,000km. The vast majority of road asphalt pavement, not only can greatly improve the driving comfort, and maintenance side is also a lot easier.Permanent deformation of asphalt pavement is the most common disease of the asphalt pavement in highway asphalt pavement damage the rut ratio up to80%.This study is the use of penetration, softening point, ductility after aging penetration ratio and other indicators of domestic natural rock asphalt modified bitumen modified asphalt performance evaluation, and Mixture than experimental design. Construction laying process, raw materials (including:quality control of asphalt, stone, etc.), and the test section laying. This article discusses the construction process and performance testing, and economic and social benefits for analysis.
