摘要
乳化橡胶沥青水泥混凝土（ＥＲＡＣＣ）是以水泥砂浆为连续相，以裹覆乳化橡胶沥青的粗集料为分散相的水泥基复合路面材料。根据ＥＲＡＣＣ路面结构特点和ＥＲＡＣＣ的微观结构特点，建立了ＥＲＡＣＣ微观热应力分析的三层嵌套模型，推导了计算公式，讨论了提高ＥＲＡＣＣ抗温缩开裂能力的途径。
Rubberized asphalt emulsion modified cement concrete (ERACC) is a kind of cement based pavement composite which is made of cement mortar as matrix, and rubberized asphalt emulsion coated coarse aggregates as dispersed phase. According to the features of ERACC pavement structure and the characteristics of ERACC microstructures, a three layer built in model was proposed for microscopic thermal stress analysis of ERACC, and the thermal stress formulas were developed. The way to increase the ability of resisting temperature cracking was discussed.
