The invention relates to an anti-cracking interlayer for an asphalt pavement, and belongs to the field of composite materials. The anti-cracking interlayer is arranged between the surface layer and the base layer of the asphalt pavement, and comprises a stress absorbing film layer, a superpolymer layer, a high-strength tire base layer and a self-adhering superpolymer layer from the top down. The anti-cracking interlayer has the intelligent functions such as self checking, self controlling and self repairing, as well as vital signs, and has the advantage that stress in the base layer can be dispersed and absorbed automatically, so as to prevent and slow down the generation and the expansion of crack on the pavement, control pavement crack and associated diseases, and prolong the service life.
