RESULTS OF OKLAHOMA FLEXIBLE PAVING RESEARCH PROJECT
FROM 1955 TO 1962 THE OKLAHOMA HIGHWAY DEPARTMENT STUDIED PLATE-BEARING AND BENKELMAN BEAM TESTS ON EXISTING ROADS AND THE EFFECTS OF SOILS, CLIMATE, TRAFFIC AND OTHER FACTORS. A PAVEMENT DESIGN METHOD WAS DEVELOPED AND A SOILS MANUAL WAS PUBLISHED. RECENTLY CONSTRUCTED PROJECTS GIVING UNSATISFACTORY SERVICE WERE INVESTIGATED AND STUDIES WERE MADE TO DETERMINE THE CAUSES OF POOR PAVEMENT PERFORMANCE. THESE WERE UNDERDESIGN FOR THE LOAD ASSUMED, DEFECTIVE MATERIALS IN THE BASE, OVERLOADED, POOR SUBBASE MATERIAL, SHRINKAGE OF SUBGRADE SOIL AND WATER ENTERING THROUGH THE SURFACE. /RRL/
