    Abstract:

    The curing technology of high viscosity emulsified-asphalt(HVE) super viscous wear layer still has some shortcomings, such as excessive noise, insufficient anti-loosening performance and poor durability, which restricts is the popularization and application. The effects of waste rubber powder, talc powder and glass fiber on the wear resistance performance, rutting resistance performance and noise reduction performance of thin slurry mixture with HVE super viscous wear layer were studied by orthogonal experiment, and the mixture ratio was optimized by analytic hierarchy process. The results show that when the above three materials are mixed, the influence of thin slurry mixture of HVE super viscous wear layer on wear resistance performance is shown as follows: glass fiber, rubber powder and talcum powder; the influence degree of rutting resistance performance is that of rubber powder, glass fiber and talcum powder; the degree of influence on noise reduction performance is that of rubber powder, talcum powder, glass fiber. When the optimal mixing ratio is 2.5% of rubber powder, 4.5% of talc powder and 0.35% of glass fiber, HVE super viscous wear layer thin slurry mixture has the characteristics of strong wear resistance, rutting resistance and low noise.
