ROAD TEST FINDINGS UTILIZED IN ANALYSIS OF TEXAS TRIAXIAL METHOD OF PAVEMENT DESIGN

STUDIES WERE MADE IN TEXAS TO IMPROVE ON THE APPLICABILITY AND EFFICIENCY OF TEXAS TRIAXIAL PAVEMENT DESIGN. THIS SUMMARY SHOWS: (1) HOW BOTH WASHO AND AASHO ROAD TEST DATA WERE USED TO IMPROVE THE TEXAS TRIAXIAL METHOD, (2) THE LITERATURE ON THE TEXAS TRIAXIAL METHOD WAS BROUGHT UP TO DATE, AND (3) THE RESULTS OF THE IMPROVED METHOD CORRELATE WITH PERFORMANCE OF ROAD TESTS. THE WASHO ROAD TEST AND THE AASHO ROAD TEST, TOGETHER WITH THE CALIFORNIA COHESIOMETER TEST, WERE OF CONSIDERABLE ASSISTANCE IN DEVELOPING AND ANALYZING THE TEXAS TRIAXIAL METHOD OF PAVEMENT THICKNESS DESIGN. THE IMPROVED TEXAS METHOD CORRELATES SATISFACTORIALLY WITH THE AASHO ROAD TEST, BUT FURTHER IMPROVEMENTS WILL BE STUDIED CLOSELY. AN IMPROVED TRIAXIAL METHOD IS PRESENTED WHICH UTILIZES LOCAL MATERIALS AND THEIR STABILIZATION TO THE EXTENT THAT SEMI-FLEXIBLE PAVEMENT SYSTEMS ARE IN MANY CASES A GREAT ECONOMIC FACTOR. THE IMPROVED TEXAS TRIAXIAL METHOD PROVIDES FOR TESTING OF MIXTURES FOR ALL INDIVIDUAL LAYERS RATHER THAN THE ARBITRARY ASSIGNMENT OF FACTORS OR STRUCTURAL NUMBERS TO MULTITUDES OF COMBINATIONS. THE TEXAS TRIAXIAL ACCELERATED PROCEDURE IS BEING APPLIED TO TESTING OF BASE MATERIALS FOR FIELD CONTROL IN SEVERAL TEXAS HIGHWAY DISTRICTS.
