Research Of Polyester Fiber Reinforced Asphalt Mixture Performance And Engineering Application

With the axle load traffic and the constant increased, asphalt Pavement there have been some early damage phenomenon. Especially in the special climate of China's central areas, therefore, how to Improve the asphalt mixture road traffic performance is the primary task of scientific research workers. Adding reinforcing fiber is to improve asphalt mixture performance of a new method. This method was widespread concern and importance. relevance and application of research was to be rapidly and continuously. Because having a good road performance, simple construction, and reasonable economic characteristics , polyester fiber reinforced asphalt mixture in recent years have been more and more attention and application. Because fiber asphalt pavement used in China not long ago, there are many issues that must be resolved In the central region to promote the use of it. In order to perfect the fiber asphalt pavement,on the basis of the analysis to the fiber asphalt mixture enhancement mechanism, and through a reasonable choice material, in this paper a lot of laboratory research on polyester fiber asphalt mixture is studied:By Marshall test of different doses of polyester fiber mixture , we analyzed the changes in the underlying law;Through polyester fiber asphalt mixture rutting test, cold water bending test and stability test, we systematically analyzed the pair of asphalt mixture high temperature stability, low-temperature crack resistance, water stability from polyester fiber. And based on this, this paper studies the polyester fiber asphalt mixture application in engineering:Through analysis laboratory studies, this paper presents polyester fiber asphalt mixture ratio of the design method; Combining test sections, the paper summarizes the polyester fiber asphalt mixture construction technology; This paper also explored polyester fiber asphalt mixture of technical feasibility and economic advantages. The research topics of the polyester fiber asphalt mixture provide a reliable basis and technical support to the application in Anhui.
