The present invention belongs to the field of plastic modification, and specifically relates to a long afterglow luminescent pavement material and a preparation method thereof. In parts by weight, the material is obtained by blending and extruding 15–30 parts of modified luminescent masterbatch A, 45–150 parts of rigid resin particles B, 3–6 parts of unsaturated monomer, 0.2–0.5 parts of initiator and 0.2–0.4 parts of antioxidant through a twin-screw extruder. The modified luminescent masterbatch A comprises, in parts by weight, 20–40 parts of luminescent powder, 0.01–0.03 parts of surface modifier for stirring and infiltration, 4–12 parts of compatibilizer, and 0.5–2 parts of dispersant. The luminescent particles of the present invention have excellent afterglow effect, are easy for overlay construction, have good adhesion, high strength and wear resistance, and controllable shape and size.
