REVIEW OF EXISTING THEORIES AND METHODS OF PAVEMENT DESIGN

PAVEMENT DESIGN THEORIES AND METHODS ARE CLASSIFIED INTO FOUR GROUPS WITH BRIEF BIBLIOGRAPHIES. THE ELASTICITY METHODS CONSIDERS THE BEHAVIOR OF PAVEMENTS UNDER WORKING CONDITIONS, WHEN DEFLECTIONS, BY ASSUMPTION, REMAIN PROPORTIONAL TO APPLIED LOADS. STRESSES AND STRAINS ARE LIMITED AS DETERMINED BY CALCULATIONS BASED ON THEORY OF ELASTICITY. THE ULTIMATE STRENGTH METHODS ARE CONCERNED WITH PAVEMENT BEHAVIOR AT FAILURE. THUS, PAVEMENTS MUST CONTAIN AN ADEQUATE SAFETY FACTOR AGAINST ASSUMED SHEAR FAILURE. THE SEMI-EMPIRICAL AND STATISTICAL METHODS ARE BASED ON CONDITIONS UNDER WHICH PAVEMENTS OF CERTAIN COMPOSITION AND STRENGTH HAVE EXPERIENCED PERFORMANCE FAILURE. THICKNESSES ARE DETERMINED ON THE BASIS OF PROPERTIES OF PAVEMENT MATERIALS. THE EMPIRICAL AND ENVIRONMENTAL METHODS ARE BASED ON THE RELATIONSHIP OF PAVEMENT THICKNESS TO SOIL AND ENVIRONMENTAL CONDITIONS. SOIL CLASSIFICATION TESTS ARE USED TO DETERMINE PAVEMENT SUBGRADE CHARACTERISTICS.
