摘要
介绍沥青混合料离析产生的原因,对比分析目前沥青混合料离析评价方法的优缺点。基于无核密度仪在高速公路路面工程沥青混合料离析评价中的应用,指出无核密度仪对于沥青混合料离析程度的定量评价具有可行性、可靠性和便捷性,可以大范围推广应用。
This paper introduces reasons of segregation of asphalt mixture, compares and analyzes advantages and disadvantages of present evaluation methods for segregation of asphalt mixture. Based on application of non - nuclear density gauge in evaluation of segregation of asphalt mixture in pavement project of expressway, the paper points out feasibility, reliability and convenience of non - nuclear density gauge for quantitative evaluation for degree of segregation of asphalt mixture, and it can be popularized to apply in large scope.
