Study On The Coordination Proportion Design Of SMA Mixture From Shandong Province

Embarks from the Shandong Province local climate characteristic, the local commonly used material and the SMA blend unique feature, This article analyses the structural characteristics of SMA mixture, makes a detailed research on asphalt matrix and aggregate graduation. And research modified asphalt, modified asphalt SMA and its the road performance, This article gives an elaborate discourse on influence on asphalt matrix with variation of fiber and mineral filler content, Subsequently the influence on volume index with the change of aggregate graduation is analyzed. By means of indoor and road test of SMA mixture, High temperature stability and low temperature crack resistance performance of SMA is discussed. In order to suit the Shandong Province zone characteristic the SMA blend design, the construction has provided the good instruction function.
