摘　　要：对灌注式半柔性路面材料当中所用的普通水泥砂浆进行性能优化,在普通水泥砂浆中添加乳化沥青、橡胶粉等作为改性材料,最终制备形成CA砂浆。以流动度、泌水率、抗折抗压强度、体积收缩率作为主要控制指标,通过一系列配合比优化试验制备出性能最佳的CA砂浆。The performance optimization of the common cement mortar used in the cast-in-place semi-flexible pavement materials is carried out,and the emulsified asphalt and rubber powder are added in the common cement mortar as the modified materials,so as to prepare CA mortar finally.Taking the fluidity,bleeding rate,compressive strength and flexural strength and volume shrinkage rate as the main control indexes,CA mortar with the best performance is prepared through a series of mix proportion optimization tests.
