UTILIZATION OF INDUSTRIAL POLYETHYLENE AND POLYPROPYLENE WASTE PRODUCTS IN THE FORM OF A SPECIAL ROAD SURFACING OR A WEARING COURSE

VERWERTUNG INDUSTRIELLER POLYAETHYLEN- UND POLYPROPYLENABFAELLE IN FORM EINES SPEZIALSTRASSENBELAGES BZW. EINER VERSCHLEISSSCHICHT

A GOOD WEARING COURSE WHICH CAN BE LAID QUICKLY IS REQUIRED FOR BRIDGES, MOTORWAY ENTRANCES AND EXITS, TUNNEL ENTRANCES, STOPS, ETC. INDUSTRIAL POLYETHYLENE AND POLYPROPYLENE WASTE PRODUCTS, REDUCED TO A PARTICLE SIZE OF ABOUT 2.5 MM AND INTENSIVELY MIXED FOR SOME MINUTES WITH HEATED CHIPPINGS IN THE RATIO 1:9, RESULT IN A NEW KIND OF HIGH-GRADE ROAD SURFACING AFTER SETTING. THIS SURFACING IS SUPERIOR TO CONVENTIONAL ASPHALT AND GUSSASPHALT SURFACINGS SINCE IT HAS GREATER ELASTICITY, GREATER RESISTANCE TO ABRASION, AND IS INSENSITIVE TO FLUCTUATIONS IN TEMPERATURE, OIL, SALT, FUEL, ETC. LABORATORY TESTS HAVE SHOWN THAT IT IS TECHNICALLY POSSIBLE TO USE THE METHOD. AN ATTEMPT IS TO BE MADE TO MARKET THE METHOD.
