沥青面层旧料再生利用试验研究

Experimental Research on Recycling Waste Materials in Asphalt Pavements

高等级公路沥青路面面层旧料的再生利用是一个重要的课题。为掌握沥青面层铣刨旧料冷再生材料性能,以某公路的沥青面层铣刨旧料为试验对象,设计了二灰稳定再生、水泥稳定再生以及水泥粉煤灰复合稳定冷再生配合方案,并进行了室内试验,最后结合实际工程需求,对三种方案进行综合比较,提出一种资源上环保、技术上可行、经济上节俭的沥青旧料冷再生利用方案。

Recycling waste materials in asphalt pavements on high -grade highways remains an lmportam subject. In order to master the performance of the cold recycling materials for waste asphalt pavemill materials, .the waste asphalt pavemill materials on xx road is taken as the experimental object to design the mixing proportions of lime- fly ash stabilized recycling , cement stabilized recycling and cement -fly ash stabilized cold recycling respectively, and indoor experiments are conducted. By incorporating practical engineering demand and comparing the three plans, an environmentally- friendly, technically- feasible and cost- effective plan for cold recycling of waste asphalt materials is proposed in this article.
