摘　　要：温拌沥青混合料(WMA)是一类使用特殊添加剂或制备工艺技术来达到节能环保目的的混合料。通过对国内外研究资料的总结发现,现有的温拌沥青混合料配合比设计方法及施工温度确定有一定的不合理性。该文对温拌沥青混合料配合比设计及温拌沥青混合料的合理施工温度进行基础性研究,并为温拌沥青混合料的合理施工温度提供一定的参考,并通过旋转压实试验对比温拌沥青混合料与热拌沥青混合料的压实特性。The warm mixed admixture(WMA) is an admixture used of the special additive or preparing technological technique to reach the objective of energy saving and environmental protection.Through the summarization of the studying materials at home and abroad,it is discovered that the existing design method of mixing ratio and the determination of construction temperature of warm mixed admixture have some irrationality.The article basically studies the mixing ratio design and the reasonable construction temperature of warm mixed admixture,provides some reference for the reasonable construction temperature of warm mixed admixture,and contrasts the compacting characteristics of warm mixed admixture with the hot mixed admixture by the spiral compacting experiments.

关 键 词：温拌沥青混合料 拌和温度 水稳定性 压实特性
