摘　　要：泡沫冷再生沥青混合料的参数主要包括级配、最佳含水量、沥青以及水泥的含量。在尽量利用再生混合料的级配基础上,此研究以最大压实干密度确定最佳含水量,以劈裂、残留强度等确定最佳沥青及水泥用量。在一定的水泥、沥青等用量的基础上,用马歇尔击实成型试件,研究强度、密度等随龄期的变化。Gradation of mixtures, the best water, asphalt and cement content are the main parameters in the study of CRAM. On the basis of making full use of RAP, the best water content was studied according to the maximum density, and the best asphalt and cement content was made according to the strength including spilt and unconfined compression test. According to the study above, the change of strength and density with age was studied.

关 键 词：级配 最佳含水量 最佳沥青水泥用量 强度 龄期
