基于表面活性技术的温拌沥青混合料应用研究

温拌技术是指采用新工艺或者新材料,实现原材料相同条件下拌和温度与压实温度的降低,同时做到保留或者改善热拌沥青混合料原有性能的沥青混合料拌和技术。主要介绍国内外应用较为广泛的基于表面活性剂,即采用直投式DAT温拌添加剂实现温拌的沥青混合料生产工艺,并结合工程实例,分析温拌技术的实践效果。以期待对温拌技术应用提供科学的参考建议,并促进节能减排低碳环保的温拌沥青混合料更好地发展。

Application Study of Warm Mixture Asphalt Based on Surface Active Technology

Warm mixture asphalt technology refers to use the new technology or the new materials to realize mixing temperature and compaction temperature lower under the condition of the same raw materials,at the same time to keep or improve original performance of hot mix asphalt mixture.This paper mainly introduced the production technology of asphalt mixture based on surfactant additives which were widely used at home and abroad,named DAT,belonged to the straight cast type.By introducing the production process and ...
