摘　　要：为探究不同玄武岩与石灰岩质量配比的混合集料的耐磨耗性及其AC-13混合料的抗滑性能,测试了不同掺配比例玄石混合集料的磨耗值、磨光值、混合集料及AC-13混合料的动态摩擦系数衰减速率、衰减终值及抗滑寿命。结果表明:7个玄石混合集料掺配组的磨耗值均满足相关指标要求,混合集料中玄武岩质量比越大,其抗滑耐磨性能越好。向石灰岩中掺配硬质石料可降低其衰减速率,提高衰减终值及抗滑寿命,改善抗滑性能。In order to explore the abrasion resistance of mixed aggregates with different basalt and limestone mass ratios and the slip resistance of AC-13 mixture,the abrasion value and polishing value of basalt mixed aggregates with different mixing ratios and the dynamic friction coefficient attenuation rate,final attenuation value and anti-slip life of mixed aggregates and AC-13 mixture are tested.The results show that:the abrasion values of seven mixing groups of basalt mixed aggregates meet the requirements of relevant indexes,and the larger the mass ratio of basalt in the mixed aggregate,the better the slip resistance and abrasion resistance.The mixing of hard aggregated rocks into limestone can reduce its attenuation rate,increase the final attenuation value and anti-slip life,and improve the slip resistance.
