摘要
高模量沥青混合料(high modulus asphalt mixture, HMAM)因具有良好的综合性能,被运用于重载路面中。沥青路面回收料(reclaimed asphalt pavement, RAP)是路面维修养护过程中铣刨出的废旧材料。对掺加硬质沥青颗粒制备成的高模量沥青混合料,以及向高模量沥青混合料中掺加RAP重新拌和成的高模量再生沥青混合料的复数模量、高温稳定性、低温稳定性、水稳定性和疲劳性能进行测试,试验结果表明,基于高掺量RAP的高模量再生沥青混合料表现出较好的高温抗车辙性能、低温抗裂性能、抗水损害性能以及疲劳性能。
High modulus asphalt mixture has been applied in heavy-duty pavement due to its excellent comprehensive performance.Reclaimed asphalt pavement(RAP)is a waste material that is milled out during road maintenance and repair.The dynamic modulus,high temperature stability,low temperature stability,water stability,and fatigue performance of high modulus recycled asphalt mixture prepared by adding hard asphalt particles and high modulus recycled asphalt mixture remixed with RAP were tested.The experimental results show that the high modulus recycled asphalt mixture based on high content RAP exhibits good high-temperature rutting resistance,low-temperature cracking resistance,water damage resistance,and fatigue performance.
