沥青混合料热再生配合比设计与经济性分析

Asphalt mixture thermal regeneration design and economic analysis

主要对再生沥青混合料设计要点进行了分析,并对再生剂用量的确定进行了试验,采用马歇尔击实方法确定了新集料比例与沥青含量,通过路用性能试验表明设计满足要求,经济性分析表明热再生技术具有良好的经济效益和市场推广价值。

This paper mainly analyzes the key points in the design of recycled asphalt mixture material,test were determined using the regenerant,compaction method of recycled asphalt mixture were aggregate ratio and asphalt content determined Marshall,through road performance test show that the design meets the requirements,economic analysis shows that the heat regeneration technology has good economic effect and market value.
