DEFLECTION STUDY OF FLEXIBLE PAVEMENT OVERLAYS

BEGINNING IN 1968, BENDELMAN BEAM DEFLECTION TESTS WERE RUN ON 25 BITUMINOUS ROADWAYS LOCATED THROUGHOUT THE STATE. TESTS WERE RUN BEFORE OVERLAY, JUST AFTER THESE PROJECTS WERE OVERLAYED, ONE YEAR AFTER, AND TWO YEARS AFTER. THE RESULTS WERE ANALYZED TO DETERMINE THE STRENGTHENING EFFECT OF THE BITUMINOUS OVERLAY. IN CONJUNCTION WITH THIS STUDY, BENKELMAN BEAM TESTS WERE RUN AT VARIOUS SHORT INTERVALS ON A NUMBER OF RANDOMLY SELECTED FLEXIBLE PAVEMENTS. THESE RESULTS WERE USED TO DEVELOP A TESTING SCHEDULE (NUMBER AND LOCATION OF TEST POINTS REQUIRED) IN ORDER TO ASSESS THE DEFLECTION CHARACTERISTICS OF A FLEXIBLE PAVEMENT WITHIN A GIVEN DEGREE OF ACCURACY. /NTIS/
