DEVELOPMENT OF TECHNIQUES FOR APPLYING RESINOUS SKID-RESISTANT SURFACES TO HIGHWAYS

TWO PAPERS WERE PRESENTED ON A NEW TYPE OF RESINOUS MATERIAL FOR SURFACING PORTLAND CEMENT AND BITUMINOUS CONCRETE HIGHWAYS. THIS SURFACING MATERIAL, CALLED RELCOTE, UTILIZES A MODIFIED EPON RESIN BINDER WHICH, ON THE ADDITION OF A CATALYST, SETS CHEMICALLY TO A TOUGH THERMOSETTING PLASTIC. WHILE STILL IN THE LIQUID STATE, THE RESIN IS APPLIED TO THE ROADWAY, AND SHARP, ABRASIVE GRIT SUCH AS CRUSHED QUARTZ, EMERY, OR ALUNDUM IS BROADCAST OVER THE SURFACE. WHEN THE RESIN SETS CHEMICALLY, THE GRIT IS PERMANENTLY FIXED IN PLACE. THE PROCEDURE IS DESCRIBED TO RESURFACE A BRIDGE IN WHICH THE ROADWAY WAS ESSENTIALLY A POROUS SURFACE WITH A LARGE PERCENTAGE OF POLISHED AGGREGATE EXPOSED. THE FOLLOWING PROCEDURE WAS USED: (1) HEAVY TAR AND GREASE SPOTS WERE REMOVED, (2) THE ENTIRE SURFACE WAS ETCHED WITH HYDROCHLORIC ACID TO INSURE A LASTING BOND BETWEEN THE RESINOUS BINDER AND THE CONCRETE, (3) THE RELCOTE PAVER APPLIED THE RESIN BINDER, (4) A 50-50 MIXTURE OF COARSE GARNET AND 20-26 MESH ALUNDUM WAS USED AS THE ABRASIVE MADIUM, AND (5) THE COATING WAS ROLLED IMMEDIATELY AFTER THE EXCESS GRIT WAS PLACED ON THE SURFACE. A SURFACE WAS ACHIEVED HAVING OUTSTANDING RESISTANCE TO WEAR, A WATER- TIGHT MEMBRANE AND LASTING SKID RESISTANCE.
