The microwave heating self-healing pavement in the frozen soil area comprises an upper surface layer, a middle surface layer, a lower surface layer and a shielding layer, wherein the upper surface layer, the middle surface layer and the lower surface layer are sequentially arranged from top to bottom, ferrite particles are doped in the upper surface layer, the middle surface layer and the lower surface layer, and the shielding layer comprises two SBS modified asphalt layers and one steel wire velvet layer between the two SBS modified asphalt layers. The method for designing the material composition of the pavement mainly comprises the steps of calculating the maximum mixing amount of ferrite particles according to the design thickness of the pavement by designing a semicircular test piece to fit the relationship between the mixing amount and the healing rate of the ferrite particles, obtaining the optimal mixing amount, and calculating the optimal mixing amount of steel velvet in a shielding layer. The invention overcomes the defects of the prior art, effectively improves the self-healing effect of the microwave heating pavement and prevents the frozen soil base layer from melting by determining the optimal addition amount of the ferrite particles of the asphalt pavement and arranging the shielding layer.)
