PREFORMANCE STUDY OF THE BITUMINOUS CONCRETE SECTION O E THE JOHN F. KENNEDY EXPRESSWAY (I-95)

THE MAIN OBJECTIVE OF THIS STUDY IS TO EVALUATE THE STRUCTURAL ADEQUACY OF THE RECENTLY REHABILITATED AND RESURFACED FLEXIBLE PAVEMENT SECTION OF THE JFK EXPRESSWAY (I-95). THIS EVALUATION WILL BE DONE USING THE "ASPHALT INSTITUTE'S DEFLECTION METHOD FOR DESIGNING ASPHALT CONCRETE OVERLAYS FOR ASPHALT PAVEMENTS." RESULTS OF BENKELMAN BEAM STATIC REBOUND DEFLECTION TAKEN BEFORE AND AFTER RESURFACING I-95 INDICATE THAT THE RESURFACING WITH FOUR INCHES OF BITUMINOUS CONCRETE HAS IMPROVED THE STRUCTURAL CAPACITY OF THE PAVEMENT SECTION. RESULTS OF DYNAMIC DEFLECTION TESTS RUN WITH THE "ROAD RATER" CORRELATE POORLY WITH THE BENKELMAN BEAM STATIC REBOUND TESTS. AS A RESULT OF THE FIRST YEAR OF DEFLECTION TESTING, IT IS RECOMMENDED THAT DYNAMIC TESTS USING THE "ROAD RATER" BE DISCONTINUED. DEFLECTION TESTS FOR THE REMAINDER OF THIS INVESTIGATION WOULD THEN BE CONTINUED USING THE BENKELMAN BEAM REBOUND DEFLECTION METHOD RECOMMENDED BY THE ASPHALT INSTITUTE. /FHWA/
