废旧沥青混合料的回收再利用是推动节能减排的重要举措.针对RAP(废旧沥青混合料)利用率较低等问题,提出全比例温拌再生沥青混合料的技术方案,实现100%RAP利用率,同时以马歇尔试验确定最佳外掺剂用量.将全比例温拌再生沥青混合料与常规热拌沥青混合料进行性能比对.结果表明:再生AC-13C沥青混合料的60、70 ℃车辙动稳定度分别为6 364、3 158次/mm,低温弯曲破坏应变为2 834με,其水稳定性等路用性能测试指标也满足现行规范的技术要求.
Pavement Performance of Full-scale Warm Mix Recycled Asphalt Mixture
The recycling and reuse of waste asphalt mixture is a crucial initiative for promoting energy conservation and emission reduction.In order to address the issue of low RAP(reclaimed asphalt pavement)utilization rate,technical solution for full-scale warm mix recycled asphalt mixture is proposed,achieving 100%RAP utilization rate.Meanwhile,the optimal dosage of admixture is determined through the Marshall Test.A comparative analysis of the performance between the full-scale warm mix recycled asphalt mixture and the conventional hot mix asphalt mixture is conducted.It reveals that the rutting dynamic stability of the recycled AC-13C asphalt mixture at 60 ℃ and 70 ℃ is 6 364 and 3 158 times/mm,respectively.Its flexural strain at low-temperature failure is 2834 με.Additionally,the pavement performance indicators such as water stability also meet the technical requirements of the current specifications.
