摘　　要：水泥是一种碱活性很高的建筑材料,具备作为填料充当矿粉的条件。该文依托双通高速,在矿粉中适当掺入水泥并测试混合料的常规路用性能,结果表明,水泥作为填料部分替代石灰岩矿粉,可以有效改善沥青混合料的水稳定性、高温稳定性,延长混合料疲劳寿命,但对低温开裂性能影响不大。Cement is a kind of alkaline activity building material and has the same condition of the mineral powder as a packing. This paper based on Shuang-Tong Expressway and test the pavement properties of asphalt mixture with a little cement replaced the mineral powder. The results show that the cement as a packing can effectively improve the water stability and high temperature stability of the asphalt mixture, and a little effect on the ability of crack at low temperature.
