| In recent years, fiber reinforced asphalt mixture with its good road performance, simple construction process and the characteristics of attention. In this paper, through the literature review and the science and technology novelty search, one is to seek the mineral fiber instead of lignin fiber SMA pavement feasibility, and through research to improve mineral fiber SMA asphalt mixture design and construction quality control technology index, forming a whole set of mineral fibers of SMA asphalt mixture design, construction technical guidelines to guide similar engineering construction stage.In this paper, combined with the Chongqing freeway mineral fiber SMA-13test road paving engineering, mineral fiber to carry on the omni-directional demonstration of comprehensive application of SMA-13pavement structure. This paper studies the performance of asphalt mortar, mineral fiber mineral fiber SMA-13mix design, mineral fiber SMA-13performance of asphalt mixture, and the pavement recycling technology. Combined with the construction of the Chongqing ring expressway construction guide, the final analysis of the pavement of the social and economic benefits. To evaluate the application of mineral fiber in SMA-13asphalt pavement, in order to design and construction of similar projects for reference. |
