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。
According to the RAP of the Beijing section of the Beijing-Zhuhai Expressway, the mix design of the recycled asphalt mixture and the road performance test were carried out with three material schemes. The results showed that within the range of the suitable blending ratio of the old material, , The recycled asphalt mixture has better technical performance indicators of road performance, which can basically meet the requirements of the fresh asphalt mixture. The incorporation of the regenerative agent effectively improves the road performance of the recycled asphalt mixture.
