In view of the serious characteristics of low-temperature crack disease of asphalt concrete pavement in cold and arid areas,the low-temperature crack resistance of asphalt pavement was studied.In the design of SMA asphalt mixture,the amount of modified asphalt horseshoe in the mixture was increased,the tensile properties of the binder were enhanced,and the low-temperature crack resistance of the mixture was improved by determining the high limit of the amount of modified asphalt,the amount of fiber stabilizer and the dosage of mineral powder.
