TRIAXIAL TESTING METHODS USABLE IN FLEXIBLE PAVEMENT DESIGN

TRIAXIAL TESTS MAY BE CONDUCTED UPON EACH COMPONENT OF BOTH THE ROAD SURFACE AND THE FOUNDATION INDIVIDUALLY AND CALCULATIONS MADE TO DETERMINE THE THICKNESS OF EACH MATERIAL WHICH IS REQUIRED UPON THE SUBGRADE. WHEEL LOAD, DEFLECTION, SAMPLING, SATURATION, AND LATERAL PRESSURE ARE DISCUSSED. TEST DATA PERMIT THE DETERMINATION OF VOLUME, AREA, STRESS, AND STRAIN. THE MODULUS OF DEFORMATION IS CALCULATED USING CURVES OF THE STRESS AND STRAIN VALUES. THIS IS USED TO CALCULATE THE REQUIRED THICKNESS OF EACH COMPONENT OF THE ROAD STRUCTURE. TRIAXIAL TESTING IS ALSO USED TO DETERMINE PERMISSIBLE LOADS ON EXISTING HIGHWAYS AND AIRPORTS. /AUTHOR/
