为确定泡沫温再生沥青混合料中旧路面铣刨料(RAP)的合理添加比例,进行了不同RAP掺量(质量分数,全文同)下泡沫温再生沥青混合料目标配合比设计及其路用性能分析,研究结果表明:随着RAP掺量的提高,泡沫温再生沥青混合料高温性能及力学强度得到提升;低温性能降低;水稳定性先提高后降低.综合考虑路用性能和经济性,推荐泡沫温再生沥青混合料适宜的RAP掺量为30%.
In order to determine the reasonable proportion of old pavement milled material (RAP) in foam warm recycled asphalt mixture, the design of the target mix ratio of foam RSP mixture under different RAP content (mass fraction, the same text) The results show that with the increase of RAP content, the high temperature performance and mechanical strength of the foam warm recycled asphalt mixture can be improved, the low temperature performance decreases, the water stability first increases and then decreases, and considering the road performance and economy, The recommended RAP content of foam warm recycled asphalt mixture is 30%.
