摘　　要：HVE超黏磨耗层预养护技术仍存在着噪声过大、抗松散性能不足、耐久性差等缺点,制约着HVE超黏磨耗层预养护技术推广应用。采用正交试验考察了废橡胶粉、滑石粉和玻璃纤维对HVE超黏磨耗层稀浆混合料的耐磨性能、抗车辙性能与降噪性能的影响,利用层次分析法进行配合比优选。结果表明:上述3种材料复掺时HVE超黏磨耗层稀浆混合料对耐磨性能的影响程度为:玻璃纤维、橡胶粉、滑石粉;对抗车辙性能的影响程度为:橡胶粉、玻璃纤维、滑石粉;对降噪性能的影响程度为:橡胶粉、滑石粉、玻璃纤维。最佳配合比为橡胶粉掺量2.5%,滑石粉掺量4.5%和玻璃纤维掺量0.35%时,HVE超黏磨耗层稀浆混合料具有强耐磨、车辙和低噪声的特点。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.
