摘要
针对京珠高速公路湖北段的铣刨旧料(RAP),采用3种材料方案进行了再生沥青混合料配合比设计及路用性能试验,试验结果表明,在合适的旧料掺配比例范围内,再生沥青混合料有较好的路用性能技术指标,基本能达到新鲜沥青混合料的指标要求;再生剂的掺入有效地改善了再生沥青混合料的路用性能。
To counter old Recycling Asphalt Pavement （RAP）material in Jing-Zhu Expressway of Hubei Province,three material schemes are adopted to make design and road performance tests of recycling asphalt mixture. The results indicate that recycling asphalt mixtures have better road performance index when the proportion of the RAP is in appropriate scope, and basically reach the index of the new asphalt mixture; asphalt rejuvenator can effectively improve the road performance of recycling asphalt mixture.
