摘　　要：在分析半刚性材料冲刷机理的基础上,提出一种改善水泥稳定碎石抗冲刷性能的方法,即使用废旧沥青混合料细颗粒取代水泥稳定碎石中的细集料。通过冲刷试验研究了不同废旧料细颗粒掺量对水泥稳定碎石抗冲刷性能的影响,并分析了冲刷试验结果产生的机理。试验结果表明,掺入一定掺量的废旧沥青混合料细颗粒可以明显改善水泥稳定碎石的抗冲刷性能,废旧沥青混合料细颗粒的最佳掺量为15%。The paper proposed a method which is based on analyzing the erosion mechanism of semi-rigid material to improve the anti-erosion performance of cement stabilized aggregate.The method is using fine parti-cles of recycled asphalt mixture to replace fine aggregate of cement stabilized aggregate.The influence of different content of fine particles of recycled asphalt mixture on the erosion performance of cement stabilized aggregate is studied by erosion testing.Then the mechanism of the results of erosion tests is analyzed.Tests results showed that cement stabilized aggregate mixed with a certain content of fine particles of recycled asphalt mixture can significantly improve the performance of anti-erosion of cement stabilized aggregate,and the optimum mix amount is about 15%.
