温拌沥青混合料水分特性影响因素的研究进展

Research Progress on Influencing Factors of Moisture Characteristics of Warm Mix Asphalt Mixture

基于节能减排和绿色环保的理念,温拌沥青混合料已经在世界各国得到了越来越广泛的应用。由于生产施工温度比热拌沥青混合料低,而且受到温拌技术的影响,水损害则被认为是WMA混合料的主要问题之一。对此,讨论分析了WMA混合料水敏感性的影响因素。研究得出,骨料、沥青和添加剂等对其水分特性发挥着重要作用。此外,压实温度和其他温拌技术也显著影响其水分特性。

Based on the concepts of energy saving,emission reduction and green environmental protection,warm mix asphalt has been widely used in countries around the world.Water damage is considered to be one of the main problems of WMA mixtures due to the lower production temperature than hot mix asphalt and the influence of warm mix technology.In this regard,the influencing factors of water sensitivity of WMA mixture were discussed and analyzed.The study concluded that aggregates,asphalt and additives play important roles in its moisture properties.In addition,compaction temperature and other warm mixing techniques also significantly affect its moisture characteristics.
