摘　　要：为提高沥青路面的耐久性,我国已在一级公路上结合本地原材料、气候环境、交通组成等特点,做过柔性基层沥青路面结构试验路,但并未进行较为系统的室内研究,也未形成系统的柔性材料设计方法。通过大量室内试验,分别采用GTM、马歇尔方法成型手段进行柔性基层材料对比设计和路用性能研究。通过不同级配混合料的GTM成型试验可知,GTM设备更适合于连续密实级配ATB沥青混合料的配合比设计。In order to improve the durability of asphalt pavement, flexible base asphalt pavement structure road test has been made on the Class I highway combined with local raw materials, climate and traffic composition in China. But relatively systematic laboratory study and systematic flexible material design method have not been researched in the present. Through a lot of laboratory tests, flexible base material comparison design & road performance are studied by GTM and Marshall modeling methods. Different graded mixture of GTM molding tests can show that, GTM devices are more suitable for the mix design of continuous dense grading ATB asphalt mixture.
