The invention relates to a self-cleaning fiber-reinforced internal hydrophobic anti-skid wear-resistant porous concrete pavement material, and belongs to the technical field of concrete. The self-cleaning fiber-reinforced anti-skid wear-resistant porous concrete pavement material is prepared from Portland cement, modified waste tire rubber powder, modified lignin, modified polyvinyl alcohol fiber, fly ash, coarse aggregate broken stone, graded coarse quartz sand, graded fine quartz sand, aluminum powder, quicklime powder, calcium polyacrylate, sodium isopropyl naphthalene sulfonate and calcium lignosulphonate. The component A is prepared from polyether modified heptamethyltrisiloxane and water; according to the porous concrete pavement material obtained by the invention, the compressive strength is 41.2 to 43.4 MPa, the breaking strength is 5.1 to 5.8 MPa, the contact angle is 116 to 124 degrees, the permeation coefficient is 7.7 to 8.2 mm/s, the 28-day abrasion loss is 0.34 to 0.42 kg/m < 2 >, the BPN value
