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%。Abstract: The impact of adding rubber particles on the water stability, wear resistance and other road performances of slurry mixture were compared by using wet track abrasion test, load wheel test and stability and resistance to compaction test.The attenuation characteristics of tyre vertical vibration that happened on micro-surfacing adding rubber particles were studied through tyre-road vibration test device.Test result shows that the workability of slurry mixture is improved by adding rubber particles, the mixing time is prolonged, the early strength decreases by a small margin, and bitumen aggregate ratio is needed to raise by about 1% to achieve the same road performance.When the content of rubber particles is not more than 5%, the requirement of wheel rut deformation on micro-surfacing pavement is met.Comparing with traditional micro-surfacing pavement, the attenuation coefficient of vertical vibration increases by 3%-13% on micro-surfacing pavement adding 2%-5% rubber particles overlayed asphalt pavement, and the attenuation coefficient of vertical vibration increases by 16%-24% on that overlayed cement pavement.
