基于高性能再生剂的大比例RAP厂拌热再生技术

High Proportion RPA Plant Hot Recycle Technology Based on High Efficiency Regenerant

目前,我国公路沥青路面材料循环利用率不到30%,远低于发达国家90%以上的循环利用率的水平。影响厂拌热再生RAP添加量的主要因素是缺乏高性能的再生剂,在基于高性能再生剂的基础上,将RAP掺量提高到50%,进行路用性能研究,并铺筑了试验段。

At present,the recycling rate of the asphalt materials in our country is less than 30%,while developed countries are more than 90%.Key factor that affect add dosage of plant hot recycle RAP is the lack of high efficiency regenerant.On the basis of high efficiency regenerant,the content of RAP increased to 50%.We study the road performance of high content RAP asphalt mixture in laboratory,and pave test section.
