摘要
稳定型橡胶沥青是一种新型改性沥青,具有分散性好,适用多种级配类型混合料,其性能接近SBS改性沥青.选用RLC、PCM-P、RHC 3种稳定型橡胶改性剂,通过试验最终确定3种改性剂的最佳掺量分别为12%、14%、18%.通过AC-13C沥青混合料配合比设计及马歇尔试验确定RLC、PCM-P、RHC 3种稳定型橡胶改性沥青、SBS、橡胶沥青的最佳油石比.对不同改性混合料进行高温抗车辙试验、低温抗开裂试验,水稳定性试验,试验结果得出:PCM-P对混合料高温抗车辙能力改善效果最优,RHC对混合料低温抗开裂能力改善效果最优,RHC对混合料抗水毁能力改善效果最优.
Stable rubber asphalt is a new type of modified asphalt,which has good dispersibility and is suitable for many kinds of graded mixtures. Its performance is close to SBS modified asphalt. In this paper,RLC,PCM-P and RHC are selected as three kinds of stable rubber modifiers. Through the test,the optimum content of the three modifiers is determined to be 12%,14% and 18%,respectively. Through the mix design of AC-13 C asphalt mixture and Marshall test,the best asphalt aggregate ratio of RLC,PCM-P and RHC is determined. The results show that PCM-P has the best effect on improving the high temperature anti rut ability,RHC has the best effect on improving the low temperature anti cracking ability,and RHC has the best effect on improving the water damage ability.
