In order to analyze the relationship between the technical properties of asphalt and the content of calcium sulfate whisker basalt fiber, calcium sulfate whisker/basalt fiber composite modified asphalt was prepared by mechanical stirring method, and the technical properties of modified asphalt mortar were measured. The results showed that:Modifier content and the correlation between asphalt technical nature indicators, using grey relational analysis it is concluded that calcium sulphate whisker and basalt fiber adding amount on the asphalt performance influence degree for shear strength > softening point> Fmax > 25 ℃ Cone Penetration > 5 ℃ ductility, through comprehensive score method modifier dosage is: the best calcium sulphate whisker was 4%, 4% basalt fiber.
