USE OF PAVEMENT EVALUATION TECHNIQUES IN MAINTENANCE MANAGEMENT BY THE NEW YORK STATE THRUWAY AUTHORITY

PAVEMENT EVALUATION REPORTS ARE USED AS A MANAGEMENT TOOL ON THE NEW YORK THRUWAY. PROJECTIONS COVERING LONG-RANGE MAINTENANCE ARE UPDATED ANNUALLY BY RUNNING A ROUGHOMETER SURVEY OVER THE ENTIRE THRUWAY. SERVICE LIFE CURVES ARE ADJUSTED IF NECESSARY BY THE FOLLOWING FACTORS: (1) YEARLY TRAFFIC VOLUMES WHICH ARE AUTOMATICALLY TABULATED FROM TOLL RECORDS, (2) COMPARISON OF THE ROUGHOMETER SURVEYS, (3) ESTABLISHMENT OF NEW PAVEMENTS SERVICEABILITY ON NEW VALUES AND OVERLAYS, AND (4) OCCASIONALLY CRACK AND PATCH SURVEYS ARE CONDUCTED IN LOCAL AREAS. AN ANNUAL VISUAL INSPECTION IS MADE EACH SUMMER BY THE SUPERINTENDENT OF MAINTENANCE, A LOCAL DIVISION ENGINEER AND TWO MEN FROM THE CHIEF ENGINEER'S OFFICE. SINCE THIS WORK FALLS INTO THE CATEGORIES OF RESURFACING, INSTALLATION OF ADDITIONAL DRAINAGE, AND ADDED IMPROVEMENTS FOR SAFETY, MOST OF THESE PROJECTS ARE HANDLED BY CONTRACTING FIRMS. AFTER THE INSPECTION AND APPROVAL OF WORK FOR CONTRACT, THRUWAY OFFICE ENGINEERS PREPARE CONTRACT DOCUMENTS DURING THE WINTER AND EARLY SPRING. OPERATING FUNDS FOR NORMAL PAVEMENT MAINTENANCE ARE PROVIDED ON A CALENDAR YEAR BASIS. THE PAVEMENT EVALUATION REPORTS AND SUBSEQUENT LONG-RANGE POLICY WHICH IS ESTABLISHED TENDS TO STABILIZE THE PAVEMENT MAINTENANCE PROGRAM.
