WHEEL-LOAD-STRESS COMPUTATIONS RELATED TO FLEXIBLE PAVEMENT DESIGN

THE TEXAS TRIAXIAL METHOD OF FLEXIBLE PAVEMENT DESIGN WAS INFLUENCED BY CALCULATIONS BASED ON BOUSSINESQ'S EQUATIONS OF ELASTICITY TO ESTIMATE STRESSES BENEATH A WHEEL LOAD. SOME SPECIFIC CALCULATIONS ARE PRESENTED WHICH WILL AFFORD A COMPARISON BETWEEN SOME METHODS OF FLEXIBLE PAVEMENT DESIGN AND THE TEXAS HIGHWAY DEPARTMENT METHOD. THESE COMPUTATION METHODS ENABLE COMPUTATION OF SUBGRADE STRESSES FOR COMPARISON WITH THOSE OBTAINED IN LABORATORY TESTS OF TRIAXIAL SPECIMENS. THE DEVELOPMENT OF A MOHR ENVELOPE FOR EACH PARTICULAR WHEEL LOAD IS INVOLVED.
