| Abstract: | The key technique of mix design of Stone Matrix Asphalt(SMA) is to ensure that its framework is of dense structure with(reasonable) volumetric structure.These structures depend either on the component materials and construction craft or on the judgment(criterion).On the basis of laboratory tests, in-site investigation and composition design of SMA mix,the relationship between mineral(aggregate) gradation and framework and dense structure of SMA mix is analyzed,and the impact of fine aggregate variety and compacting runs on the specimen's amples volumetric structure parameters is analyzed.The constructive suggests are provided based on the above discussion results. |

| Keywords: | stone matrix asphalt mix framework and dense structure gradation void of coarse aggregate variety of fine aggregate |
