摘　　要：与石油沥青相比,特立尼达湖沥青(TLA)中含有较高的矿物质(灰分)。分析了不同灰分含量的TLA对改性沥青混合料基本性能的影响,在此基础上确定合理的灰分含量范围,为控制天然沥青灰分沉淀离析提供了参考。Compared to petroleum bitumen,Trinidad Lake Asphalt(TLA)contains a higher mineral content(ash).The influence of TLA with different ash content on the basic properties of modified asphalt mixture was analyzed,and a reasonable ash content range was determined based on the analysis,which provided a reference for controlling the ash precipitation segregation of natural asphalt.

关 键 词：特立尼达湖沥青 灰分 天然沥青改性沥青混合料 路用性能
