AN EVALUATION OF THE CORPS OF ENGINEERS PAVEMENT DESIGN CRITERIA UTILIZING THE RESULTS OBTAINED FROM THE AASHO ROAD TESTS

THE ANALYTIC COMPARISON REPORTED HEREIN COMPARES THE CURRENT CORPS OF ENGINEERS DESIGN CRITERIA WITH THE RESULTS OBTAINED ON THE AASHO ROAD TEST. THE COMPARISON INCLUDES STUDIES OF PAVEMENT PERFORMANCE, REINFORCED PAVEMENTS, PAVEMENT PUMPING, EDGE LOADING VERSUS INTERIOR LOADING, AND PAVEMENT DESIGNS. BASED ON THE RESULTS OF THE ANALYTIC COMPARISON, IT IS SHOWN THAT: THE ANALYSIS OF THE DATA FROM THE AASHO ROAD TEST WAS INCONCLUSIVE, FOR THE MOST PART, DUE TO THE LARGE NUMBER OF ITEMS WHICH DID NOT FAIL AND TO THE WIDE POINT SCATTER FOUND IN THE TABULATION OF THE DATA. THE PERFORMANCE OF THE AASHO ROAD TEST ITEMS SEEMED TO INDICATE THAT THE CORPS OF ENGINEERS NORMAL DESIGN LINE WAS CONSERVATIVE WHEN THE ITEMS WERE ANALYZED UNDER EDGE LOADING CONDITIONS. THE DECREASE IN SLAB THICKNESS ALLOWED BY THE CORPS OF ENGINEERS FOR REINFORCED PAVEMENTS SEEMED REASONABLE. SLABS WERE ANALYZED USING BOTH THE EFFECTIVE SLAB THICKNESS AND THE ACTUAL SLAB THICKNESS. THE CORPS OF ENGINEERS DESIGN METHOD WAS LESS SENSITIVE TO TRAFFIC DENSITY, AND THE RANGE OF AVERAGE DAILY TRAFFIC INVESTIGATED, THAN THE AASHO INTERIM GUIDE. /AUTHOR/
