温拌沥青混合料环境评价与性能研究

温拌沥青混合料与传统的热拌沥青混合料相比,其拌和与压实温度相对较低,减少了能源的消耗和废气的排放,并具有较好的路用性能,是一种新型的节能环保型道路材料,具有十分广阔的应用前景。为了促进温拌沥青的推广应用,基于热动力方程对四种温拌沥青混合料进行能耗和温室气体排放计算,分析各自路用性能,总结温拌沥青在应用中存在的不足。

Performance Study and Environmental Evaluation of Warm Mix Asphalt

Compared with hot mix asphalt（HMA）, warm mix asphalt（WMA）, which reduces the mixing and compaction temperatures and energy consumption and emissions, while maintaining the quality of HMA, is a new energy-saving and environment-friendly paving material with a broad prospect. In order to promote the warm mix asphalt, energy content and greenhouse gas emissions are evaluated based on thermal dynamic equation, the pavement performances of the warm mix asphalt are summed up, and then the problems of warm mix asphalt in application are analyzed.
