Study On The Inter-layer Function For Asphalt Pavement Basing On Semi-rigid Base Course In Expressway

Semi-rigid asphalt pavement because of their high-strength, anti-permanent deformation ability to adapt to the heavy traffic, etc. At present, China has become the highway road surface in the form of the main structure. But also less than satisfactory. Attention and research-based surface treatment process on the surface, reducing water damage and to prevent reflection cracks on the surface quality of service and essential to life.This article from the current reality of China's road construction, fully absorbed in domestic and foreign research results on the basis of theoretical analysis, laboratory test and a large number of engineering practice, on the highway between layers of asphalt pavement layer functions: bonding layer, layer through, under the Formation mechanism layer closure, the role of the choice of materials, construction technology and the amount of a systematic study. The key is to coat thoroughly, seal is the key to bonding. In this paper, through laboratory test that is more suitable for modified asphalt emulsion used as a sticky layer of oil; studied emulsified asphalt and kerosene as a dilution of asphalt through semi-rigid material to infiltrate the effect of different grass-roots health, as well as their age, made second, the stability of rock and cement stability in the gray rubble of the best grass-roots level through the material and the best amount of sprinkling cloth; research and analysis of the different layers under seal closure tier through a combination of materials, combined with different materials, different substrate materials for seal the amount of material, as well as surface-layer shear strength, at the same time on different types of closure under the floor of the bonding effect of research. This article aims to study the stability of the mainly grass-roots, grass-roots water surface water to address the high-grade asphalt road surface and surface, grass-roots level with the surface of the bond issues, the future level of function between the application layer to provide reference works.
