PAVEMENT MANAGEMENT USING VIDEO IMAGING TECHNIQUES

THE ADVENT OF AVAILABLE HIGH SPEED IMAGE PROCESSING TECHNIQUES WILL PROVIDE TREMENDOUS DATA PROCESSING BENEFITS OVER CURRENT HAND TECHNIQUES IN PAVEMENT MANAGEMENT. THE LONG AND COSTLY FRAME BY FRAME ANALYSIS USING PHOTOGRAPHIC TECHNIQUES OR VISUAL OBSERVATION OF EXISTING ROAD PAVEMENT SURFACES CAN BE REDUCED TO A HIGHLY ORGANIZED DATA BASE FOR EFFECTIVE AND MUCH NEEDED COST EFFECTIVE PAVEMENT MANAGEMENT SYSTEMS. PAVEMENT CONDITIONS CAN BE EASILY MONITORED THEREBY PROVIDING AN ACCURATE TECHNIQUE FOR PERFORMANCE AND COST PREDICTIONS, BUDGET REQUIREMENTS TO MAINTAIN THE ROADWAY SYSTEM, AND THE ESTABLISHMENT OF MAINTENANCE PRIORITIES. THE RESEARCH OBJECTIVES ADDRESSED HEREIN ARE TO INVESTIGATE THE FEASIBILITY OF USING A SLIT SENSOR FOR OBSERVING PAVEMENT SURFACES, DETERMINATION OF PROCESSOR ALGORITHMS FOR THE DETECTION OF PAVEMENT DISTRESS,DETERMINATION OF SCORING PROCEDURES BEST SUITED TO VIDEO IMAGING AND DETERMINATION OF THE PERTINENT DATA LOGGING REQUIREMENTS. SUCCESSFUL RESEARCH IN THESE AREAS WILL RESULT IN THE CONTINUED DEVELOPMENT OF AN ACCEPTABLE PAVEMENT MANAGEMENT SYSTEM.
