高比例厂拌热再生沥青混合料配合比设计

摘要

对于高比例厂拌热再生生AC- 25沥青混合料配合比设计的试验研究,需要对RAP集料进行考虑和对新沥青标号的确定,并进行混合料路用性能验证,试验结果表明45％ RAP掺量的AC - 25再生沥青混合料的水稳定性、高温稳定性均满足规范要求,并且表现出了良好的高温性能.%Studying of the mixture ratio design testing of asphalt mixture -25 with high ratio of plant mixing and hot regeneration, which need to consider about RAP and ascertain the new asphalt label, then should to verify the pavement performance of asphalt mixture. The outcome of the test indicates that the water stability,high temperature stability of asphalt mixture -25 with 45% RAP both satisfy the regulation and the high temperature stability is excellent
