| Abstract: | In order to evaluate the interlocking property of coarse aggregates in dense discontinuous graded asphalt mixture accurately,a determination of the minimum of voids in coarse aggregate and the new criterion of skeleton interlocking of this type of mixture were presented.Accordingly,the coarse aggregate void filling method(CAVF) was improved and applied to design this type of mixture.And then,road performances of the designed mixture were tested by Marshall test,soggy Marshall test,freeze-thaw split test and... |
