橡胶颗粒沥青混合料性能研究

Study on Capability of Crumb Rubber Asphalt Mixture

摘要: 为了研究橡胶颗粒沥青混合料的路用性能，通过水稳定性、高温稳定性、低温抗裂性以及抗剥落性方面，对不同粒径、不同掺量的橡胶颗粒沥青混合料进行了对比。试验结果表明：橡胶颗粒的加入对沥青混合料的路用性有明显的改善作用，当掺量在3%时，对沥青混合料的改善效果达到最优。

Abstract: In order to evaluate durability of rubber particles asphalt mixture, through water stability, high temperature stability, low temperature crack resistance and anti stripping property, the different amount of crumb and different particle sizes of rubber asphalt mixture were compared. Experimen-tal results show that the addition of rubber particles can improve the durability of asphalt mixture remarkably. When the dosage is 3%, the improvement effect of asphalt mixture is optimal.
