摘要:: 传统热拌沥青混合料由于需要在较高温度下生产和施工，不仅会消耗大量的能源，而且还会严重影响环境质量。因此，如何降低沥青混合料的拌合温度、减少污染与能耗，已成为道路工程界研究人员共同关注的科学问题和技术热点。温拌沥青混合料的出现为该技术难题提供了一种新颖、高效的解决思路。基于此，较为全面地介绍了温拌沥青混合料的发展历程，综述了国内外已有的温拌技术及其工作原理，评价了温拌沥青混合料的路用性能，阐述了制备温拌沥青混合料的新技术和新进展。以期为道路工程界工程师在合理运用温拌技术设计沥青混合料和启发学者探索沥青混合料温拌技术的新方法、新方向等方面提供帮助。

Abstract:: Due to its preparation and construction process being under relatively high temperature, traditional hot mix asphalt would result in not only a lot of energy consumption but also serious environmental pollution. Therefore, how to reduce the mixing temperature of asphalt mixture, as well as decrease environmental pollution and energy consumption, has become a common scientific issue and a technical hotspot for the researchers in road engineering area. The emergence of warm mix asphalt (WMA) has provided a novel and efficient solution for this technical problem. In the present work, the development history of WMA was introduced comprehensively. The warm mixing technologies existed worldwide and their technical mechanisms were summarized. The pavement performance of WMA was evaluated, and its novel preparation technologies and progress were described. It is in the hope that this paper could be helpful for the engineers to utilize the warm mixing technologies properly in designing asphalt mixtures and researchers to explore the new methods and directions of warm mixing technologies.
