【Abstract】 The article summarizes the design methods of America, Europe, Japan and China. Based on the international study methods and the local design standards, the article introduces the detailed mixing ration design flow and method and puts forward the detailed technical indexes of asphalt, coarse aggregate, fine aggregate and mineral powder. Relying on the practical viaduct engineering, the article evaluates the noise reduction property, anti-slide performance and drainage capability. The result shows that the OGFC asphalt pavement performance designed by the design method in the article is better with the good durability.According to the viaduct characteristics and aiming at the problems of unsmooth pavement drainage and roadside waterlogging, the drainage layer thickness and the drainage facilities are optimized, and the detailed optimization design measures are proposed.更多还原
