摘要
通过对利用胶粉改善沥青混合料与普通沥青混和料技术性能的试验对比分析表明,由于掺入胶粉增强了沥青混合料的粘度与韧性,使得沥青路面的高、低温稳定性、水稳定性以及耐老化性明显提高,全面改善了沥青混和料的技术性能.
By way of experiment analyses to contrast the waste rubber powder modified HMA with the ordinary HMA,the high and low temperature stability,water stability and ageing-resistant ability of bituminous pavement are remarkably improved due to the strengthening of viscosity and toughness by adding rubber powder.The technical performance of HMA has been overall improved.
