Modified asphalt research in increasing the road service performance

Aiming at the problems existing in the asphalt pavement,it introduces the adaptation ratio design of the modified asphalt mixture,does the rut assay and freeze-thaw cleavage crack test,represents the construction technology of the asphalt pavement,does detection to the asphalt concrete on the cover of the working sector,and brings forward the suggestions about the modified asphalt usage on the roads,which will generalize the application of this modified asphalt.
