摘　　要：为了评价高弹粗糙橡胶颗粒沥青混合料(HRRAM)中不同掺量的橡胶颗粒对混合料路用性能的影响,文章采用二次双面马歇尔成型试验方法对不同橡胶颗粒掺量(橡胶颗粒质量与矿料质量之比为0%、1.5%、2.5%、3.5%)的HRRAM进行系统优化配合比设计,并分别对沥青混合料的高温性能、水稳定性能、低温抗裂性能以及抗渗性能进行了试验研究。试验结果表明:橡胶颗粒的掺量控制在1.5%~2.5%,HRRAM具有更显著的路用性能。In order to evaluate the effect of rubber particles with different content in HRRAM on the road performance of the mixtures, this article used the two-stage double-sided Marshall forming test method to conduct the system optimization mix ratio design for HRRAM with different rubber particle content （the ratio of rubber particles mess to aggregate mess is 0%, 1.5%, 2. 5%, and 3. 5%）, and conducted the experimental study on the high-temperature performence,water stability performance, low-temperature crack resistance and impermeability performance of asphalt mixture. The experimental results showed that： when the content of rubber particles is controlled between 1.5% and 2. 5%, HRRAM has more remarkable road performance.
