Abstract

Abstract

In order to study the influences of different molding methods on the performances of asphalt macadam mixtures and the indices of mixture tests, three molding methods were utilized, including large scale Marshall molding method, rolling molding method and vibrating molding method, the Marshall indices of asphalt macadam mixtures compacted by the three methods were compared, and the volume indices of asphalt macadam mixtures with different vibration times were analyzed.Based on the principle of same compaction power, the ranges of four indices designed by using rolling molding method and vibrating molding method were put forward aimed at asphalt macadam mixtures.Test result shows that the ranges of different indices aimed at the two methods are nearly same, only with a difference of 5% in asphalt saturation degree, and enough compaction time is required for asphalt macadam mixtures in construction and compaction, so that they have good road performances.
