摘　　要：通过橡胶沥青混合料级配关键筛孔通过率的设计控制,对GTM压实法与马歇尔击实法设计结果进行对比结果表明,选择合理的设计方法,控制级配曲线关键筛孔的通过率,设计适当的矿粉含量是提高橡胶沥青混合料高温稳定性的关键针对橡胶沥青混合料的特点,建议在具备条件时最好采用GTM压实法;并提出应根据中国实际情况,进一步研究马歇尔击实法与GTM设计法的有效结合。Through controlling the passing rate design of key sieve of rubber asphalt mixture, the results of GTM and Marshall compaction method are compared. The results show that selecting suitable design method, controlling the passing rate of key sieve and designing optimal mineral powder content are very important for im- proving the high temperature performance of rubber asphalt mixture. According to the properties of rubber asphalt mixture, it is proposed that the GTM design method should be selected when the equipment is available. According to China＇s actual situation, further research of effective combination of this two design methods is put forward.
