| Abstract: | The steel slag of Liuzhou Steel(Group)Co.is selected as coarse aggregate and its performances is tested by the numbers,then a dense gap graded friction course asphalt mixture using that steel slag as coarse aggregate is designed with coarse aggregate void filling method(CAVF).In this paper,several craft parameters are adjusted during design and manufacture of the steel slag asphalt mixture because of the steel slag's characteristic of contour structure.The laboratory examination shows that performance of the designed steel slag asphalt mixture meet the requirements of SMA. |
