| 摘 要： | 为探究AM型温拌剂对沥青混合料水稳定性的影响,文章分别测定了添加0.5%AM型温拌剂前后的沥青三大指标和粘附性,并对AM温拌沥青混合料和对应基质沥青混合料试件,分别进行了浸水马歇尔试验和冻融劈裂试验。结果表明:添加0.5%AM温拌剂后,沥青结合料的针入度和延度增加而软化点降低;沥青混合料试件残留稳定度提高5.23%,其残留强度比提高11.16%,添加AM型温拌剂后沥青混合料的水稳定性有一定程度的提高。

| Abstract: | In order to investigate the effect of AM warm mix asphah additive on water stability of asphalt mixture, AC - 13C asphalt mixtures were prepared with 0.5% AM content. The Immersion Marshall Test and freeze - thaw split test is carried out to evaluate wa- ter stability of 2 kinds of asphalt mixtures,which were ordinary asphalt mixture and AM asphalt mixture. The results show that：with the addition of 0.5% AM warm mix agent, the residual stability increased by 5. 23% , while the residual strength ratio increased by 11.16%. |
