摘要
从掺加外加剂的角度,研究了掺加外加剂对水泥稳定碎石基层易密性的影响,并分析了单掺减水剂和粉煤灰、双掺减水剂和粉煤灰在最大干密度时减水剂和粉煤灰的掺量。结果表明:最能改善骨架密实型水泥稳定碎石易密性的几种外加剂掺量,同时也可以起到改善水泥稳定碎石的路用效果。
The impact of mixing additive on compact ability of cement stabilized macadam base was studied, and the mixing amounts of water reducing agent and fly ash when mixed respectively or altogether under maximum dry density were analyzed. The results show that several additives can not only enhance the compact ability of dense skeleton type of cement stabilized macadam base, but also improve the road performance.
