摘　　要：为了对鸭绿江大桥ERS铺装体系中的高粘高弹沥青混合料SMA-11的路用性能进行研究,对高粘高弹沥青以及高粘高弹沥青混合料SMA-11进行了试验,并与普通改性沥青混合料进行了对比,结果表明,高粘高弹沥青以及高粘高弹沥青混合料的高低温性能均优于普通改性沥青及普通改性沥青混合料SMA,高粘高弹沥青混合料更适宜用于钢桥面铺装中,高粘高弹沥青高温粘度较大,在配合比设计以及施工过程中要注意混合料的工作性能以及沥青在管路中的流动性能,研究成果可以为类似工程提供参考。In order to study the road performance of high viscosity and high elastic asphalt mixture SMA-11 in the ERS system of the Yalu River Bridge,in this paper,high viscosity high elastic asphalt and high viscosity high elastic asphalt mixture SMA-11 were tested,compared with the conventional modified asphalt mixture,the results show that the high and low temperature performance of high viscosity high elastic asphalt and high viscosity high elastic asphalt mixture is better than that of the conventional modified asphalt and the conventional modified asphalt mixture SMA,the high viscosity and high elastic asphalt mixture is more suitable for steel deck pavement,the high viscosity high elastic asphalt have a greater viscosity at high temperature,in the mix design and construction process should pay attention to the working performance of the mixture and the flow performance of asphalt in the pipeline,the research results can provide a reference for similar projects.
