摘　　要：针对水泥稳定类与二灰稳定类材料存在的问题,提出水泥粉煤灰稳定碎石基层,并对水泥粉煤灰稳定碎石的配合比设计及其性能进行了研究。研究表明,添加一定比例的粉煤灰后,水泥稳定碎石的各种路用性能均有所提高。In view of problems in materials with cement stabilized or cement -flyash stabilized gravels, this article presents the base course using cement -flyash stabilized gravel, with analysis on the mix design and its performance. It has been shown that road performance of cement stabilized gravel in all aspects has improved after adding flyash to it in some proportion.
