摘　　要：参考AC-13沥青混合料级配,将橡胶颗粒代替沥青混合料中部分细集料,以骨料的形式加入到沥青混合料中,通过室内马歇尔试验分析橡胶颗粒对沥青混合料马歇尔力学指标的影响研究表明:加入橡胶颗粒后沥青混合料的马歇尔稳定度将会降低,流值增加;采用小粒径的橡胶颗粒比采用大粒径的橡胶颗粒的沥青混合料的马歇尔稳定度提高,流值降低;采用石油沥青比采用SBS改性沥青的橡胶颗粒沥青混合料的马歇尔稳定度低。Reference to the AC-13 asphalt mixture gradation,the rubber particles instead of part of the fine aggregate were added to the asphalt mixture as aggregate.Through indoor Marshall test the effect of the rubber particles on the asphalt mixture Marshall mechanical index was analyzed.The results show that by adding the rubber particles the Marshall stability of the asphalt mixture is reduced,and the flow value is increased. Comparing with the large particle size of rubber particles,the use of small particle size rubber particles can improve the Marshall stability,and the flow valus decreases.The Marshall stability of rubber particles asphalt mixture by using petroleum asphalt is lower than that by using SBS modified asphalt.
