摘要
本文通过室内试验,对首都机场高速公路大修中上面层采用的湖沥青加5%SBS改性沥青混合料路用性能进行了研究,结果表明:与5%SBS改性沥青相比,加入20%湖沥青后的改性沥青混合料的低温稳定性、高温稳定性、疲劳性能、水稳定性等路用性能都有不同程度的提高,是一种值得推广的沥青路面上面层材料。
Based on the indoor test,the road performance of Trinidad Lake asphalt（TLA） added with 5% SBS-modified asphalt mixture as the upper layer of pavement maintenance in Capital Airport Highway is analyzed.The result shows that the road performance of 20% TLA added with 5% SBS-modified asphalt mixture is better to varying degrees than 5% SBS-modified asphalt mixture in such aspects as low-temperature stability,high temperature stability,fatigue performance,water stability and so on.So TLA added with SBS-modified asphalt mixture is recommended as a construction material for the upper layer of asphalt pavement.
