USE OF CERTAIN SYNTHETIC RESINS IN ROAD CONSTRUCTION, INDUSTRIAL FLOORINGS AND WATERPROOFING

PLASTIC MATERIALS HAVE IN RECENT YEARS ASSUMED AN INCREASINGLY IMPORTANT PLACE AMONG MATERIALS USED IN PUBLIC WORKS. THEIR EXPANSION IS STILL LIMITED BY THEIR HIGH COST, BUT THE POSSIBILITIES THAT THEY OFFER ARE GIVING RISE TO NEW TECHNIQUES, AMOUNG WHICH THE AUTHOR MAKES A CHOICE: THE HYDROCARBONATED ROAD BINDERS, INDUSTRIAL FLOORINGS AND WATER-PROOFING. THE RESINS EXAMINED ARE POLYVINYL CHLORIDE, EPOXIES AND POLYURETHANES. POLYVINYL CHLORIDE, ADDED TO COAL TAR, ENDOWS THE LATTER WITH NEW PROPERTIES THAT ARE ENHANCED IN VALUE IN ROAD PAVING CONSTRUCTION AND IN MAKING WATERPROOF JOINTS. EPOXY RESINS OPEN UP POSSIBILITIES, NOT ONLY IN THE FIELD OF ADHESIVES BUT ALSO FOR THE PROTECTION OF SURFACES SUCH AS CONCRETE. COMBINED WITH TAR, THEY ARE INCREASINGLY USED IN THE MAKING OF THIN WATER-PROOF SURFACING ON BRIDGE DECKS. THEY ALSO ENTER INTO THE COMPOSITION OF TRIM MORTARS OR HIGH-PERFORMANCE WEAR TOPPINGS. THE POLYURETHANE RESINS, WHICH HAVE MORE RECENTLY COME INTO USE, OFFER IN ADDITION TO THEIR CURRENT USE IN THE FORM OF FOAMS CERTAIN QUALITIES THAT OFTEN MAKE THEM PREFERABLE TO EPOXIES FOR THE PROTECTION OF METAL SURFACES (ORTHOTROPIC SLABS) AGAINST CORROSION AND WEAR. THEY ARE ALSO USED IN THE FORM OF SEALING MASSES FOR CONCRETE PAVING JOINTS. /AUTHOR/
