摘要
重载交通是我国一个普遍的交通现象,改善沥青路面的高温性能受到广泛关注。通过室内试验较为全面地评价了硬质沥青混合料的各种路用性能,认为该沥青混合料不仅具有良好的高温性能和力学强度,而且具有良好的水稳定性和低温性能,适合于我国重载交通路面建设的需要。
It is especially attended the high - temperature performance of the asphalt pavement as me heavy traffic is the common phenomenon in China. Based on the systematically interior test, the paper comprehensively evaluated the hard- grade asphalt mixes performances. It is not only very good high -temperature performance and the intensity, but also very great the low - temperature performance and the moisture stability to the hard -grade asphalt mixes. The hard -grade asphalt is fully capable to be used the heavy traffic pavement structure.
