摘要
由矿粉和沥青组成的沥青胶浆是沥青混合料的重要组成部分,在工程实践中经常会因为矿粉的改变而导致沥青混合料的路用性能产生很大的变化。基于灰熵法,分析了矿粉的几种指标对沥青胶浆高温性能的影响程度,分析结果表明:矿粉密度、细度、CaCO_3含量影响显著,亚甲蓝值次之,亲水系数影响较小,这对于研究和改善沥青胶浆高温性能乃至为有耐高温要求的沥青混凝土设计提供重要的指导作用。
By the SP and asphalt composition of the asphalt mortar is an important part of asphalt mixture. In engineering practice often because of SP changes resulting great changes of road performance of asphalt mixture. Based on the gray entropy, analysis several of the indicators of SP impact of asphalt mortar high temperature performance. The results show that density, fineness, CaCO3 content have significant impacts, methylene blue values followed by, hydrophilic coefficient is less affected. For studying and improving the performance of high-temperature asphalt mortar. Even more for a high temperature of the asphalt concrete design requirements provide an important role in guiding.
