THE IMPORTANCE OF RATIONAL AND COMPATIBLE PAVEMENT PERFORMANCE EVALUATION

THE PLANNING, DESIGN, CONSTRUCTION, AND MAINTENANCE OF PAVEMENTS DEPEND IN PART FOR SUCCESS ON THE EVALUATION OF THEIR PERFORMANCE. VARIOUS PROCEDURES ARE AVAILABLE FOR THIS PURPOSE, BUT THEY SHOULD BE RATIONAL AND COMPATIBLE WITH EACH OTHER FOR THE BEST TRANSFER OF INFORMATION. THIS PAPER IS CONCERNED WITH THE IMPORTANCE OF ACHIEVING THESE GOALS OF RATIONALITY AND COMPATIBILITY IN PAVEMENT PERFORMANCE EVALUATION. THE RATIONALE UNDERLYING PAVEMENT PERFORMANCE IS DISCUSSED, AND A GENERAL FRAME-WORK FOR DEVELOPING A PERFORMANCE EVALUATION SCHEME IS DEFINED. THE PRINCIPAL APPROACHES TO MEASURING OR PREDICTING PAVEMENT SERVICEABILITY ARE REVIEWED, AND THEIR MAJOR DEFICIENCIES IN APPLICATION ARE POINTED OUT. THESE DEFICIENCIES RELATE LARGELY TO A LACK OF UNDERSTANDING OF THE BASIC PRINCIPLES GOVERNING SUBJECTIVE RATING PROCEDURES, AS WELL AS THE POSSIBLE ERRORS INVOLVED. SUGGESTIONS FOR IMPROVEMENT OF METHODS IN USE ARE PRESENTED. SEVERAL APPROACHES TO APPROXIMATING PRESENT SERVICEABILITY THROUGH CONDITION SURVEYS OR ROUGHNESS MEASUREMENTS ARE ALSO DISCUSSED. IT IS POINTED OUT THAT THESE CAN BE RELEVANT FOR A PARTICULAR AGENCY BUT ONLY QUALITATIVELY USEFUL TO THE DATA OF ANOTHER AGENCY; FURTHER, SIGNIFICANT ERRORS CAN RESULT FROM SOME OF THE TRANSFORMATIONS USED IN THESE APPROACHES. FINALLY, SEVERAL SUGGESTIONS ARE PRESENTED TOWARD ACHIEVING BETTER COMPATIBILITY WITHIN AND AMONG AGENCIES. THESE RELATE TO PRECISE DEFINITIONS, BETTER UNDERSTANDING OF SUBJECTIVE RATING PRINCIPLES, RIGOROUS ERROR ANALYSES, AND CAREFULLY DESIGNED EXPERIMENTS. /AUTHOR/
