【摘要】 采用浸水马歇尔试验和冻融劈裂试验方法,对片麻岩沥青混合料以及石灰岩与片麻岩组成的酸碱复合集料沥青混合料水稳定性进行对比研究。结果表明,复合集料沥青混合料的水稳定性得到明显提高。说明石灰岩的掺入能有效增强片麻岩沥青混合料水稳定性。更多还原

【Abstract】 Immersing Marshall test and frozen-thaw cycle test were used to investigate the moisture stability of gneiss asphalt mixture and complex-aggregate(mixture by limestone and gneiss)asphalt mixture.It can be concluded from the experimental result that the moisture stability of complex-aggregate asphalt mixture is improved significantly and this also means that the using of limestone makes a positive effect in improving the moisture stability of gneiss asphalt mixture.更多还原
