温拌技术对沥青混合料性能的影响分析

温拌沥青混合料(WMA)是指相对于同类热拌沥青混合料(HMA),通过不同技术手段,拌和温度降低30℃以上,且路用性能不降低的沥青混合料。该文汇总比较了不同机构的研究成果,各种温拌沥青混合料性能各有优缺点,因此对于温拌沥青混合料选择,需要根据当地实际情况,考虑设备、环境等因素,采用当地使用的材料进行综合试验分析,选择合适的温拌沥青混合料。

Analysis on Influence of Warm Mixing Technology on Performance of Asphalt Mixture

The warm mixing asphalt mixture is relative to the hot mixing asphalt mixture.Its mixing temperature reduces over 30℃ by the different technical means.And it is the unreduced road performance of asphalt mixture.The article collects and compares the study results of the different institutes,and the performance,advantage and disadvantage of each warm mixing asphalt mixture.Therefore,the selection of warm mixing asphalt mixture is required to base on the local practical conditions,consider the factors of equipment,environment and etc.The article analyzes the comprehensive experiments of the local used materials in order to select the suitable warm mixing asphalt mixture.
