就地热再生沥青混合料设计思路探讨

Discussion on Design Thinking of Hot In-place Recycling Asphalt Mixture

该文通过对沥青的再生分析和对废旧沥青混合料的评价,分析研究了再生沥青混合料的路用性能随再生剂掺量变化而变化的规律,以及对其性能的影响,通过再生沥青混合料马歇尔试验、车辙试验、低温试验,其结果满足热拌沥青混合料技术标准。

The article analyzes the asphalt recycling and evaluates the old asphalt mixture,analyzes and studies the variable rule of the using performance of recycled asphalt mixture with the admixing variation of recycling agent and the influence on its performance.Through the Marshall test,the rutting test and the low temperature test of recycled asphalt mixtures,the results can satisfy the technical standard of hot mixed asphalt mixture.
