THE "HOW" OF PAVEMENT PERFORMANCE EVALUATION

A GENERAL DISCUSSION IS PRESENTED OF PAVEMENT PERFORMANCE. APPROACHES TO THE PHILOSOPHY OF PAVEMENT EVALUATION ARE DIVIDED INTO TWO MAJOR PARTS: (1) SERVICEABILITY-PERFORMANCE STUDIES OF FUNCTIONAL BEHAVIOR, AND (2) MECHANISTIC EVALUATION OF STRUCTURAL ADEQUACY. A NEW DIMENSION IS BEING ADDED TO THE NEED FOR PERFORMANCE INFORMATION AS THE APPLICATION OF SYSTEMS ENGINEERING TO PAVEMENT SYSTEMS CONTINUES. AS THE SYSTEMS APPROACH TO PAVEMENT EVALUATION IS DEVELOPED, THE NEED FOR A SYSTEM OUTPUT FUNCTION IS EVIDENT. A DISCUSSION OF THE SURFACE DYNAMICS PROFILOMETER AS A TOOL FOR ESTIMATING A SYSTEM OUTPUT FUNCTION IS INCLUDED, TOGETHER WITH A BRIEF DESCRIPTION OF THE PROFILOMETER SYSTEM AND A SUMMARY OF THE ANALYSIS TECHNIQUES USED ON THE DATA. A SET OF EQUATIONS FOR PREDICTING PAVEMENTS SERVICEABILITY INDEX BASED ON A SMALL PRELIMINARY STUDY IS USED TO DEMONSTRATE THE PROCEDURES INVOLVED IN OBTAINING A MODEL FOR ESTIMATING PAVEMENT SERVICEABILITY INDEX FROM DATA OBTAINED WITH THE SURFACE DYNAMICS PROFILOMETER.
