摘要
通过对不同级配细粒式沥青混合料的研究 ,分析了集料密度和混合料空隙率的不同测试方法和计算方法对于确定沥青混合料空隙率的影响 ,对其间的异同及相互关系进行了探讨 ,提出了确定沥青混合料空隙率时应尽量避免的人为影响 ,同时对今后测定和计算方法的规范化进行了展望。
This paper analyzes some different methods for measuring and computing aggregate density and air voids of asphalt mixture, which influence on determining air voids of asphalt mixture based on the study of some different fine aggregate asphalt mixtures, discusses similarities, differences and correlations of different methods, suggests that we should avoid artificial influence on determining air voids of asphalt mixture and looks forward to standardization of measuring and computing methods
