摘　　要：针对水泥灰土稳定砂基层容易出现裂缝的现状,在水泥灰土稳定砂中掺入一定量的聚丙烯纤维,进行了有关试验研究。试验表明:与未掺加的相比,掺入聚丙烯纤维对水泥灰土稳定砂的力学性能指标有极大改善。结合实际工程,铺筑了试验路段,并对试验路段进行跟踪观测和评价分析,取得了较好的使用效果。Cement lime-soil stabilized sand is prone to cracks.According to this situation,this paper carried a series of laboratory experiments to study the effect of adding polypropylene fiber to the cement lime-soil stabilized sand.The results show that the mechanical properties of cement lime-soil stabilized sand were significantly improved with added polypropylene fiber.Combined with a practical project,a pilot testing road was paved and its performance was monitored and evaluated.The testing gave a satisfying result.
