A RATIONALE FOR ANALYSIS OF PAVEMENT PERFORMANCE
A HYPTHETICAL ROAD TEST QUITE SIMILAR TO THE AASHO ROAD TEST IS USED TO ILLUSTRATE A RATIONALE FOR DETERMINING AN ASSOCIATION OF PAVEMENT PERFORMANCE WITH VARIABLES THAT DESCRIBE PAVEMENT DESIGN AND APPLIED LOADS. THE RATIONALE USED FOR ILLUSTRATION IS ESSENTIALLY THAT USED IN THE ANALYSIS OF PERFORMANCE DATA FOR THE FACTORIAL EXPERIMENTS AT THE AASHO ROAD TEST. THE PERFORMANCE OF A PAVEMENT IS DEFINED BY A CURVE THAT SHOWS ITS SERVICEABILITY TREND AS AXLE LOAD APPLICATIONS ARE INCREASED. A MATHEMATICAL FORM OR MODEL IS SELECTED FOR THE ASSOCIATION, THEN PROCEDURES ARE DEFINED FOR FITTING THE DATA TO THE MODEL SO THAT ALL CONSTANTS IN THE MODEL ARE EVALUATED. WHEN PAVEMENT DESIGN IS GIVEN, THE EVALUATED MODEL CAN BE USED EITHER TO PREDICT SERVICEABILITY AFTER A GIVEN NUMBER OF SPECIFIED LOADS HAS BEEN APPLIED, OR TO PREDICT THE NUMBER OF SPECIFIED LOAD APPLICATIONS REQUIRED TO PRODUCE A GIVEN SERVICEABILITY LOSS. MANY DETAILS OF THE RATIONALE ARE GIVEN AS THE EXAMPLE PROCEEDS FROM HYPOTHETICAL DATA TO THE PERFORMANCE EQUATION. LIMITATIONS AND ALTERNATIVES FOR THE RATIONALE ARE DISCUSSED, A TABLE OF DISCREPANCIES BETWEEN PREDICTED AND OBSERVED PERFORMANCE IS GIVEN, AND THE ILLUSTRATIVE ANALYSIS ENDS WITH CURVES THAT MAY BE USED IN THE PRACTICAL APPLICATION OF THE DERIVED EQUATION. /AUTHOR/
