摘要
通过对挖除旧料进行级配分析、旧沥青老化与再生分析,确定再生混合料的级配、再生剂与新沥青的类型和用量进行选择,对现场热再生混合料配比设计进行了有益的探索,通过性能验证设计出合适的混合料。
Through the analysis of gradation,aging degree and recycling of the old asphalt,we can confirm the recyled mixture gradation,and select the type and amount of new asphalt or rejuvenating agent.The research has done useful exploration of recyled mixture design of hot-in-place recyling,through performance test,it designs suitable mixture.
