高掺量RAP乳化沥青冷再生混合料设计及性能研究

Research on the design and performance of emulsified asphalt cold regeneration mixture with high RAP content

采用改进后的马歇尔试验方法进行高掺量RAP乳化沥青冷再生混合料的配合比设计,最终确定出RAP料掺量为98%、水泥掺量为1.5%、乳化沥青用量为3.5%。

The emulsified asphalt cold recycled mixtures with high RAP content was designed by improved mar shall test methods,at last 98% of RAP material content,1. 5% of cement content and 3. 5% of asphalt content was used.
