OLD TIRES CONTRIBUTE TO THRUWAY MAINTENANCE

SINCE 1968, MORE THAN ONE MILLION POUNDS OF RECLAIMED DEVULCANIZED RUBBER (THE EQUIVALENT OF 50,000 TIRES) HAVE BEEN RECYCLED AS A SEALER FOR JOINTS AND CRACKS IN PAVEMENTS ON THE GOVERNOR THOMAS E. DEWEY THRUWAY IN NEW YORK. COST SAVINGS RESULTED WHEN THE RUBBER SEALER LASTED UP TO THREE TIMES AS LONG AS CONVENTIONAL ASPHALT SEALERS. A SIMPLE METHOD FOR BLENDING THE RUBBER INTO HOT ASPHALT AT THE ROADSIDE SITE WAS DEVELOPED. IT CALLS FOR ADDING RECLAIMED, POWDERED RUBBER IN A PROPORTION OF 100 POUNDS TO A 500-POUND (55 GALLON) DRUM OF ASPHALT. THE MIX IS COOKED FOR A SHORT TIME TO ALLOW THE RUBBER TO DISSOLVE INTO THE ASPHALT. AS THE SEALER IS USED, NEW ASPHALT AND RUBBER CAN BE ADDED TO THE PARTIALLY FILLED KETTLE FOR A CONTINUOUS OPERATION. PROCEDURES FOR WINTER OPERATIONS ARE ALSO DISCUSSED AS IS THE FEASIBILITY OF USING A STRESS RELIEVING INTERFACE BETWEEN OLD, CRACKED PAVEMENT AND NEW SURFACE LAYER.
