The results show that the compound of PVA sol and HS powder can remarkable reduce the retained strength above 400 ℃ and increase the moisture resistance. 结果表明,PVA-HS型复合溃散剂能大幅度降低水玻璃砂400℃以上的残留强度,改性PVA对水玻璃砂抗吸湿性有明显提高。
Results of retained Marshall Stability ( MS0) and Tensile Strength Ratio ( TSR) indicate that without additive, the moisture damage resistance of basalt asphalt mixture may not meet the specifications. 马歇尔试验残留稳定度(MS0)与冻融劈裂试验残留强度比(TSR)结果显示,无添加剂玄武岩沥青混合料的水稳定性不一定能够满足规范要求;
