基于流变测试技术的沥青评价方法研究进展

结合自身的研究,综述了沥青流变测试技术近几年的发展情况。分析认为,国内外都从影响路用性能的因素出发(包括车辆荷载、温度环境与降水、沥青材料的老化等),利用新型流变测试手段进行沥青路用性能及其行为机制的研究,并出现了较多的新型测试方法和评价技术。相对国外,国内沥青研究方法还多停留在常规分析和Su-perpave的沥青结合料的标准方法,在材料使用条件的模拟研究上,诸如频率、温度、应力水平、应变水平、界面行为等方面还存在很多测试方法创新和研究空间。

Review of Asphalt Evaluation Methods Based on Rheological Measure Technology

The performance evaluation methods based on rheological technology are mainly reviewed join-ting own study.Analysis shows that many new rheological measure methods are developed and used to evaluate asphalt properties relating to the pavement performance in present years,especially with more simulating condition including traffic load,temperature circumstance and age course,etc.In domestic research field of asphalt,traditional and superpave binder test methods are always used and more new rheological methods aiming at simulating conditions including frequency,temperature,stress level,strain level and interface behavior need to be developed and researched.
