SHEAR STRESS IN CONCRETE PAVEMENTS

THE CONVENTIONAL DESIGN OF CONCRETE PAVEMENTS IS BASED ON ON THE MODULUS OF RUPTURE OR FLEXURAL STRENGTH OF CONCRETE. THOUGH IT IS GENERALLY KNOWN THAT THE PRESENCE OF SHEAR STRESS WOULD MODIFY THE ULTIMATE MOMENT OF RESISTANCE, PRACTICALLY NO WORK HAS BEEN REPORTED TO EVALUATE THE ORDER OF SHEAR STRESS DEVELOPED IN A CONCRETE PAVEMENT UNDER VEHICULAR LOADING. BESIDES ENABLING A BETTER UNDERSTANDING OF THE RIGID PAVEMENT MECHANICS IN GENERAL, A KNOWLEDGE OF THE ORDER OF SHEAR STRESS DEVELOPED AT THE INTERFACE OF RIGID OVERLAY AND COMPOSITE RIGID PAVEMENT WOULD LEAD TO DEVELOPMENT OF A MORE RATIONAL DESIGN PROCEDURE. AN ANALYTICAL PROCEDURE IS PRESENTED FOR THE CALCULATION OF SHEAR STRESS UNDER LOAD AT CORNER, EDGE AND INTERIOR POSITIONS IN HIGHWAY AND AIRFIELD PAVEMENTS. IN THE CALCULATIONS, WESTERGAARD'S BASIC EQUATIONS FOR DEFLECTION HAVE BEEN USED. /AUTHOR/
