为提高夏季高温多雨重载交通条件下沥青路面的使用性能，通过高温性能、低温抗裂性、抗疲劳性和水稳定性试验，对比研究了AH-70和SBS聚合物改性沥青混合料的路用性能。结果表明，与70 #和70 #SBS沥青混合料相比，30 #硬质沥青混合料的高温性能得到了显著改善。此外，这些沥青混合料的水稳定性相当。30#硬质沥青混合料的疲劳性能与70#沥青混合料相当。最终，经过10年的路用性能，硬质沥青混凝土路面结构达到了最佳路用状态。(C)2019爱思唯尔有限公司版权所有。
In order to improve the service performance of asphalt pavement under high temperature and rain during summer under heavy traffic conditions, this research compared the pavement performance of hard, heavy-duty AH-70, and Styrene Butadiene Styrene (SBS) polymer-modified asphalt mixtures through high temperature performance, low temperature crack resistance, fatigue resistance, and water stability tests. Results indicate that 30# hard asphalt mixture remarkably improves high temperature performance compared with 70# and 70# SBS asphalt mixtures. Moreover, the water stability of these asphalt mixtures is comparable. The fatigue performance of 30# hard asphalt mixture is comparable with that of 70# asphalt mixture. Finally, after 10 years of pavement performance, the hard asphalt concrete pavement structure achieved the best road conditions. (C) 2019 Elsevier Ltd. All rights reserved.
