废橡胶粉改性沥青混合料的试验研究

Experimental Research on Mixture of Waste Rubber Powder and Modisfied Asphalt

通过对改性沥青掺入不同剂量的橡胶粉进行马歇尔、车辙、残留稳定度等试验,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。

By way of experiments of Marshall, rut and residual stability under admixing different dose of rubber powder into modified asphalt, the paper determines the variation in stability at high temp, waterstability and performance at low temp for the mixture of modified asphalt and rubber powder. Experimental data show various indexes of road usage performance for the asphalt mixture all get obvious improvement.
