摘要
我国对环氧沥青混合料级配设计的研究尚处于开始阶段,国际上也没有对环氧沥青混合料设计提出专门的级配设计。环氧沥青混合料广泛用于大型钢桥面铺装上,由于钢箱梁的温度变化比普通的路面要大得多,桥面铺装的温度变化范围也非常大,因此必须要求铺装材料具备优越的高低温性能,以防止出现高温车辙以及低温开裂等病害。本文就从高温稳定性出发研究级配的选择对环氧沥青混合料的影响。
Epoxy-graded asphalt mixture design of the study in China is still in the beginning stage,there is no special grade design in international epoxy asphalt mixture.Epoxy asphalt mixture is widely used in large-scale steel bridge on the pavement ,because the steel box girder temperature changes much greater than ordinary road,the bridge deck pavement temperature range is also very large,the pavement material is required with high and low temperature performance,to prevent the emergence of low-temperature and high temperature diseases,such as cracking and rutting.In this paper,starting from the high temperature stability,studied the choice of grade on the impact of epoxy asphalt mixture.
