EVALUATION OF THE APPLICABILITY OF THE AASHO ROAD TEST RESULTS TO CROPS OF ENGINEERS FLEXIBLE PAVEMENT CRITERIA

VARIOUS APPROACHES WERE INVESTIGATED IN AN EFFORT TO USE THE RESULTS OF THE AASHO ROAD TEST COMPLETED IN 1961 TO VALIDATE OR MODIFY PRESENT CORPS OF ENGINEERS /CE/ FLEXIBLE PAVEMENT DESIGN CRITERIA. THE AASHO ROAD TEST RESULTS ARE NOT DIRECTLY APPLICABLE FOR USE IN IMPROVING EXISTING CE DESIGN CRITERIA BECAUSE SUFFICIENT DATA WERE NOT OBTAINED DURING APPLICATION OF TEST TRAFFIC TO DETERMINE MATERIAL STRENGTH CONDITIONS, ESPECIALLY AT FAILURE. THE PRESENT SERVICEABILITY INDEX METHOD OF EVALUATING PAVEMENT PERFORMANCE, DEVELOPED BY THE AASHO ROAD TEST STAFF APPEARS TO HAVE CONSIDERABLE MERIT IN QUANTITATIVELY ASSESSING PAVEMENT CONDITION. HOWEVER, THE SPECIFIC VARIABLES FOR WHICH OBJECTIVE MEASUREMENTS ARE TAKEN FOR USE IN THIS METHOD OF EVALUATION ARE NOT THOSE NORMALLY CONSIDERED IN PAVEMENT DESIGN. THE VARIOUS APPROACHES FOLLOWED IN ATTEMPTING TO RELATE THE PATTERN OF BEHAVIOR REPRESENTED BY THE AASHO ROAD TEST RESULTS TO THE PATTERN INHERENT IN THE CE DESIGN PROCEDURES ARE EXPLAINED AND COMPARISONS ARE SHOWN. MATHEMATICAL PATTERNS SEEM TO BE STRONGLY PARALLEL, BUT THE SPECIFIC FIELD MEASUREMENTS NEEDED TO DRAW A DIRECT COMPARISON ARE LACKING. /AUTHOR/
