摘　　要：阐述了GTM的工作原理,并采用GTM法对柔性基层ATB-25混合料进行了设计,同时比较了与马歇尔法设计的沥青混合料体积参数及路用性能的优劣。同时结合杨北公路的柔性基层施工,对现场施工工艺进行研究。结果表明GTM法设计的柔性基层表现出良好的路用性能,以现有的压实设备,采用合理的碾压工艺能够保证其压实度,GTM设计方法完全可用到柔性基层的施工中更能保证工程质量。GTM ted . Compare it with working principle and design in ATB -25 flexible base with GTM method were expatia-asphalt compound designed with Marshall Principle in volume parameter and application properties. By Yangbei pavement flexible base construction and researching in construction process, the flexi- ble base designed with GTM shows favorable application properties. With present compacting equipment, the compacted density can be certified if rolling is right. GTM design in flexible base can ensure the project quality.
