摘要
文章分析了车辙的成因与发生机理,阐述了RA抗车辙剂对沥青混合料的作用机理,并对不同RA掺量下的沥青混合料进行了路用性能研究,证明了RA抗车辙剂能有效改善沥青混合料的稳定度、水稳定性、高温稳定性和低温抗裂性,同时确定了RA抗车辙剂的最佳掺量。
The article analyzes the cause and mechanism of rutting,and introduces the effect of RA rutting resistance agent on concrete mixture.It studies the effect of different amount of RA and concrete mixture on road pavement.It is proved that RA rutting resistance agent can effectively improve the stability of concrete mixture,water,and high temperature and low temperature anti-crack capacity.The optimal amount of RA agents is also determined in the end.
