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.
