CRACKS IN ASPHALT RESURFACING AFFECTED BY CRACKS IN RIGID BASES

IT HAS BEEN OBSERVED THAT WHERE OLD CONCRETE PAVEMENTS HAVE BEEN RESURFACED WITH ASPHALTIC CONCRETE MANY OF THE CRACKS AND JOINTS IN THE OLD PAVEMENT REAPPEAR AS CRACKS IN THE ASPHALT SURFACE. THESE ARE COMMONLY CALLED REFLECTION CRACKS. USUALLY SUCH CRACKS APPEAR IN THE RESURFACING DURING THE FIRST FEW YEARS OF SERVICE. IN THEMSELVES THE CRACKS PRESENT A MAINTENANCE PROBLEM; POTENTIALLY, THEY ARE THE STARTING POINT FOR DESTRUCTIVE FORCES WHICH CAN MATERIALLY SHORTEN THE SERVICE LIFE OF THE RESURFACING. THIS INVESTIGATION OF REFLECTION CRACKS IN ASPHALT SURFACES WAS BEGUN IN IOWA IN 1948. AT THAT TIME THREE TEST SECTIONS WERE ESTABLISHED TO PROVIDE INFORMATION CONCERNING THE GROWTH OF REFLECTION CRACKING AND ITS EFFECT ON THE SERVICE LIFE OF THE RESURFACING. IN 1949 ADDITIONAL TEST SECTIONS WERE ESTABLISHED FOR THE PURPOSE OF EVALUATING SEVERAL METHODS OF TREATING CRACKS IN THE CONCRETE BEFORE RESURFACING. /AUTHOR/
