针对重庆高温、多雨、重载地区,为提高沥青路面抗车辙、抗水损坏等性能,对湖沥青改性沥青混合料路用性能以及NS(我国南北方适用的添加剂)与湖沥青复合改性技术进行了试验研究。结果表明:添加湖沥青可提高混合料路用性能,其中高温稳定性得到显著改善,但效果均不如SBS改性沥青混合料;NS-湖沥青复合改性可以显著提高沥青混合料各项路用性能,效果优于单一湖沥青改性和SBS改性。
針對重慶高溫、多雨、重載地區,為提高瀝青路麵抗車轍、抗水損壞等性能,對湖瀝青改性瀝青混閤料路用性能以及NS(我國南北方適用的添加劑)與湖瀝青複閤改性技術進行瞭試驗研究。結果錶明:添加湖瀝青可提高混閤料路用性能,其中高溫穩定性得到顯著改善,但效果均不如SBS改性瀝青混閤料;NS-湖瀝青複閤改性可以顯著提高瀝青混閤料各項路用性能,效果優于單一湖瀝青改性和SBS改性。

For the high temperature, rainy and heavy traffic region in Chongqing, improving the resistance to rutting and water damage of asphalt pavement was very important. In view of this, the research about the pavement performance of lake asphalt modified asphalt mixture, and NS-lake asphalt compound modified technology were studied. Firstly, the addition of lake asphalt can improve pavement performance far more than common mixture, especially the high temperature performance, but the effect is low compared with SBS modified mixture. Secondly, NS and lake asphalt compound modified can significantly improve the pavement performance, with better effects than lake asphalt modified single or SBS.
