DESCRIBED IS A PAVING METHOD OF FINE WATER-PERMEABLE CONCRETE WHICH CAN BE USED FOR ROADWAYS, SIDEWALKS, BIKEWAYS, PARKING LOTS, PUBLIC SQUARES, ETC. A BASE LAYER OF WATER-PERMEABLE CONCRETE IS PAVED BY SPREADING AND POUNDING A SAND FILTER LAYER AND A RUBBLE BASE LAYER ON THE CONSOLIDATED GROUND TO HAVE POROSITY AFTER POUNDING OF 10 -20% AND A COEFFICIENT OF WATER PERMEABILITY OF MORE THAN 10 X 10-2 CM/SEC. A MIXTURE OF CRUSHED WASTE GLASS, FINE RUBBLE, 250 -500 KG/M3 OF CEMENT, WATER AT A WATER - CEMENT RATIO OF 25 - 40%, AND A POLYMER IN AN AMOUNT OF 10 -50% OF THE WEIGHT OF CEMENT USED BASED ON 50% SOLID MATERIAL IS SPREAD ON THE BASE LAYER AND POUNDED. THE CONCRETE IS AGED FOR MORE THAN ONE DAY, A MIXTURE OF A POLYMER AND WATER WAS SPRAYED ON THE BASE LAYER TO BE ABSORBED, AFTER WHICH AGING IS DONE TO COMPLETE THE CONSTRUCTION.
