A NEW PATCHING MATERIAL FOR PAVEMENT FAILURES
AN ECONOMICAL PATCHING MATERIAL FOR REPAIR OF ELASTIC TYPE FAILURES ON FLEXIBLE BITUMINOUS PAVEMENTS IS DESCRIBED. THESE FAILURES, CAUSED BY FATIGUE OF THE SURFACE FROM REPEATED DEFLECTION BY HEAVY TRAFFIC, APPEAR AS CHICKENWIRE OR ALLIGATOR PATTERN CRACKS. SHORT-TERM REPAIRS MAY BE MADE BY OVERLAYING OR OTHER COSTLY METHODS. A UNIQUE AND BETTER METHOD INVOLVES THIN APPLICATION OF A HOT ASPHALT AND RUBBER COMPOUND WITH HIGH ELASTICITY AND FLEXIBILITY AS WELL AS LOW TEMPERATURE SUSCEPTIBILITY. THE AGGREGATE IS USED ONLY FOR THIS REPAIR METHOD WAS DEMONSTRATED ON A TEST SECTION.
