摘　　要：针对热拌和冷拌沥青混合料各自的缺点,开发了一种拌和温度介于两者之间的新型沥青混合料-温拌沥青混合料。温拌沥青混合料主要有四类,其中最近开发的一类是基于乳化沥青的温拌沥青混合料。这种温拌沥青混合料拌和温度在80-120℃之间。经过国内外试验表明,基于乳化沥青的温拌沥青混合料可完全达到热拌沥青混合料的性能。Both hot mix and cold mix asphalt have distinct advantages, but their disadvantages are also well known. Researchers around the world developed a new kind of asphalt mixture - warm mix asphalt （WMA）, which mixing temperature is between hot mix and cold mix. Up to now, four kinds of WMA are well known. The latest kind is based on emulsion. The WMA＇s mixing temperature can be from 80＇C to 120C. WMA was expected to be used in road construction and maintenance just because WMA may be compacted in lower temperature and it has excellent property.
