为解决GTM方法在应用过程中出现的设计指标与马歇尔方法不一致的问题,从设计理论、室内试验及唐曹高速公路工程实践,对马歇尔方法与GTM方法的设计原理、路用性能及施工效果进行了对比分析。结果表明,与马歇尔设计方法相比,GTM方法的设计原理科学合理,设计的沥青混合料路用性能更为优良。同时,提出了对体积参数作为沥青混合料设计控制指标的看法。
In order to solve the inconsistency between the design indexes of GTM method and the Marshall method, the design principle, road performance and construction effect of Marshall method and GTM method are studied from the design theory, laboratory test and Tangcao Expressway engineering practice Comparative analysis. The results show that compared with the Marshall design method, the design principle of the GTM method is scientific and reasonable, and the designed asphalt mixture road performance is more excellent. At the same time, put forward the view of volume parameter as a control index of asphalt mixture design.
