| Abstract: | There are 2 major damages on asphalt pavement of domestic expressway： track and reflection crack. Many technologies and approaches can be used to solve early tracks on asphalt pavement. When Panzhihu-Tianfang Expressway is asphalt pavement so as middle course modified built, middle course modified with rock asphalt is adopted to improve overall capacity of to resist tracks. This paper mainly introduces the mixture ratio design and construction for with rock asphalt, as well as the existing technical issues. |
