硬质沥青用于沥青混凝土的性能研究

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。

Study of hard-grade asphalt mixes performance

It is especially attended the high-temperature performance of the asphalt pavement as the 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 pa...
