The utility model discloses a multi-regeneration functional layer drainage anti-cracking asphalt pavement maintenance structure, and belongs to the field of road engineering. The pavement maintenancestructure comprises a fresh mixed asphalt upper surface layer, a hot recycled asphalt middle lower surface layer, a hot recycled PAM asphalt flexible upper base layer, a PMRE emulsified asphalt stressabsorption layer, a cold recycled cement stabilized macadam lower base layer and a large-gap cold recycled cement stabilized macadam drainage subbase layer which are arranged from top to bottom. Compared with the prior art, the multi-regeneration functional layer drainage anti-cracking asphalt pavement maintenance structure disclosed by the utility model has the advantages that the problems of poor drainage, serious reflection cracks, poor anti-rutting performance and the like in the traditional pavement structure are solved while the old pavement milling material is fully utilized; and cyclic damage to the pavement structure is prevented, the overall service life of the pavement structure is prolonged, the effects of saving energy, reducing emission and reducing construction cost can beachieved, and good application and popularization value is achieved.
