| Abstract: | The segregation characteristics of coarse asphalt mixture were studied,AC-25C was taken as research object,the controlling principle of segregation was analyzed from the aspects of aggregate selection,material transfer,the operating parameters of paver's distribution room and paving pattern,and a controlling method of segregation was proposed.Study result indicates that for AC-25C asphalt mixture,some qualified aggregates from the specifications of S8,S9,S12,S14(S15) and S16 should be chosen.Contrasted with... |
