摘　　要：运用摆锤冲击法和均匀弹性支撑落重弯折冲击法,首次对柔性纤维水泥稳定砂砾和普通水泥稳定砂砾的冲击性能进行了对比试验研究。试验结果表明:和普通水泥稳定砂砾相比,柔性纤维水泥稳定砂砾具有优良的抗冲击能力,在路面半刚性基层中运用可以增强基层抵抗行车荷载的冲击和振动,使半刚性基层具有更加优良的动力服务性能,延长其使用寿命。This paper, for the first, has used pendulum impact method and even elastic support falling weight bend impact method to give comparison test to impact performance of flexible fiber cement stabilize gravel and common cement stabilize gravel. Test results show： Comparing with common cement stabilize gravel, the flexible fiber cement stabilize gravel has better anti - impact capability, when applying in half- rigid base course of pavement, it may improve the resistance to impact and vibration caused by driving load, and offers half rigid base coarse with better dynamic service performance and furthermore, prolong its service life.
