摘　　要：为改善大孔隙排水沥青路面承载能力差及沥青与矿料之间黏结能力低等缺点,延长其使用年限,选用AR-HVA高黏剂及玄武岩纤维对SBS聚合物改性排水沥青混合料进行复合改性,并开展高温抗车辙、低温抗开裂、水稳定性及渗水性能试验,评价AR-HVA高黏剂的掺入对排水沥青混合料相关性能的改善效果,并确定AR-HVA高黏剂的合理掺量范围。通过配合比设计,确定PA-16排水沥青混合料的矿料级配及最佳油石比。试验结果表明,随着ARHVA高黏剂掺量的增加,排水沥青混合料高低温性能及水稳定性能均逐渐升高,渗水性能未发生明显变化;从经济性及高低温性能两方面综合考虑,AR-HVA高黏剂的推荐掺量为8%,从经济性及水稳定性能两方面综合考虑,ARHVA高黏剂的推荐掺量范围为6%~8%。In order to improve the poor bearing capacity of large pore drainage asphalt pavement and the low bonding capacity between asphalt and mineral materials,and extend its service life,we used AR-HVA high viscosity agent and basalt fiber to make composite modification of SBS polymer modified drainage asphalt mixture,and carried out high temperature rutting resistance,low temperature cracking resistance,water stability and water seepage performance tests to evaluate the improvement effect of the addition of AR-HVA high viscosity agent on the related properties of drainage asphalt mixture.The reasonable dosage range of ARHVA high viscosity agent was determined.The mineral grade and the optimum oil-stone ratio of PA-16 drainage asphalt mixture were determined by the mix ratio design.The test results show that with the increase of the content of AR-HVA high viscosity agent,the high and low temperature performance and water stability of the asphalt mixture are gradually increased,and the water permeability performance does not change significantly.From the comprehensive consideration of economy and high and low temperature performance,we determined that the recommended dosage of AR-HVA high viscosity agent was 8%.From the comprehensive consideration of economy and water stability performance,we determined that the recommended dosage range of AR-HVA high viscosity agent was 6%~8%.
