The invention discloses an evaluation method of accumulated damage of a porous and elastic pavement and belongs to the technical field of performance testing on mixed materials of the porous and elastic pavement. According to the evaluation method, a porous and elastic pavement test piece is tested repeatedly through a cyclic loading test and a dynamic modulus test sequentially, so that the perimeter of a stress-strain hysteretic curve under different loading times and the work area of the stress-strain hysteretic curve at an unloading stage are determined, the accumulated damage degree of theporous and elastic pavement test piece is evaluated according to the variation amplitude of the perimeter of the stress-strain hysteretic curve under different loading times and the work area of thestress-strain hysteretic curve at the unloading stage, the defects of low detection accuracy and difficulty in accurate parameter measurement when a traditional material damage evaluation method is used for porous and elastic pavements with large porosity are overcome, and the condition is provided for optimization design of materials of the porous and elastic pavements.
