FLEXIBLE PAVEMENT PERFORMANCE IN NEW YORK STATE

A STUDY WAS INITIATED TO DETERMINE THE RELATIVE EFFECTS OF SEVERAL DESIGN AND ENVIRONMENTAL VARIABLES ON THE SERVICEABILITY OF FLEXIBLE PAVEMENTS. AFTER EXAMINING OVER 2,000 SETS OF CONTRACT PLANS, 175 PAVEMENTS LOCATED THROUGHOUT THE STATE WERE SELECTED FOR SERVICEABILITY (PSI) MEASUREMENTS. FOR COMPARISON TO THOSE STILL IN "AS-BUILT" CONDITION, ANOTHER 67 RESURFACED PAVEMENTS WERE ALSO SELECTED. IN ADDITION TO MEASUREMENTS OF RUTTING, CRACKING, PATCHING, AND ROUGHNESS NEEDED IN CALCULATING PSI'S, A NUMBER OF QUALITATIVE OBSERVATIONS WERE MADE AT THE TEST SITES, INCLUDING DRAINAGE, SHOULDER CONDITIONS, TRANSVERSE PROFILES, CENTERLINES CRACKING, EDGE CRACKING, AND RAVELING. AFTER THE INITIAL DATA WERE PARTIALLY ANALYZED, 38 REPRESENTATIVE PAVEMENTS WERE SELECTED FOR DEFLECTION MEASUREMENTS AND CORING. ON 25, TRENCHES WERE DUG IN THE SHOULDERS TO OBTAIN SAMPLES OF SUBBASE AND SUBGRADE MATERIALS. THE STUDY'S RESULTS SHOWED THAT FLEXIBLE PAVEMENTS ARE WELL CONSTRUCTED IN NEW YORK STATE AND SERVE THE MOTORING PUBLIC WELL. OF THE FOUR MAJOR VARIABLES CONSIDERED--AGE, CLIMATE, CROSS-SECTION, AND TRAFFIC--ONLY CLIMATE SHOWED LITTLE RELATIONSHIP TO PERFORMANCE, PROBABLY BECAUSE IT WAS "OVESHADOWED" BY CHANGES IN THE OTHER VARIABLES. /FHWA/
