Test Analysis of Long-Term Rutting Resistance Performance of Warm In-place Recycling Asphalt Mixture
In order to evaluate the long-term rutting resistance of warm in-place recycling asphalt mixture,accelerated loading tests were carried out with a small accelerated loading equipment(PaveMLS11)under dry conditions at 60℃and water immersion,respec-tively,and compared with hot mix recycled asphalt mixture and fresh asphalt mixture.The results show that after 1 million times of loading,the rutting depth deformation of recycled asphalt mixture is small in dry environment at high temperature of 60℃and water immersion environment at high temperature of 60℃,and the long-term rutting resistance is the best.Under the coupling effect of wa-ter and temperature,the edge warping deformation of the samples of warm in-place recycling and hot mix recycled asphalt mixture is 1.1 times and 1.3 times that of new mix asphalt mixture,and the influence of water on the long-term rutting resistance of the samples is greater than that of new mix asphalt mixture,but the influence of water on the long-term rutting resistance of warm in-place recy-cling asphalt mixture is better than that of hot mix recycled asphalt mixture.Therefore,the warm in-place recycling asphalt mixture has better long-term rutting resistance.
