胶粉改性沥青混合料的路用性能研究

Pavement Performance of Rubber Powder Modified Bituminous Mixture

主要通过在沥青混合料拌合过程中掺入不同量的橡胶粉进行马歇尔、车辙、残留稳定度、劈裂强度等试验,确定掺入不同量的橡胶粉沥青混合料的高温稳定性、水稳定性和低温性能等路用性能的变化,试验数据表明沥青混合料的各项路用性能指标都得到明显地改善和提高。

Mixing rubber powder to the bituminous mixture in the course of forming specimen,the experiments,such as Marshall, wheel rut,residual stability,cleavage strength,are carried on to observe the changing of performance such as high temperature stability,water stability and low temperature performance of the bituminous mixture that are mixed with different quantity of rubber powder.The results indicate that each performance index of the bituminous mixture has been distinctly improved.
