| 摘 要： | 采用湿轮磨耗试验、负荷轮粘附砂试验和轮辙变形试验方法, 对比分析了添加橡胶颗粒对于稀浆混合料的水稳定性、抗磨耗性等路用性能的影响。通过轮胎/路面振动测试装置, 研究了轮胎在橡胶颗粒微表处上的垂直振动衰减特性。试验结果表明: 添加橡胶颗粒改善了稀浆混合料的成浆性能, 延长了稀浆混合料的可拌和时间, 但混合料的初期强度有较小幅度降低, 达到相同路用性能其油石比需提高约1%;橡胶颗粒的掺量不超过5%时能满足微表处轮辙变形的要求; 与传统微表处相比, 橡胶颗粒掺量为2%~5%的微表处加铺在沥青路面上的振动衰减系数提高3%~13%, 加铺在水泥路面上的振动衰减系数可提高16%~24%。
