THE MECHANICAL PROPERTIES OF BITUMINOUS CONCRETE AND THE RHELOGICAL RESPONSE OF ASPHALT GREATLY INFLUENCE THE DESIGN AND CONSTRUCTION OF MULTILAYER FLEXIBLE PAVEMENT STRUCTURES AND ARE DIRECTLY RELATED TO THE REPONSE OF BITUMINOUS CONCRETE STRUCTURES TO TRAFFIC UNDER VARIOUS ENVIRONMENTAL CONDITIONS. THE EXPERIMENTAL PHASE OF THIS RESEARCH INVOLVED THE TESTING OF FIVE DIFFERENT TYPES OF ASPHALTIC CONCRETE MIXTURES IN WHICH TWO AGGREGATE TYPES, TWO AGGREGATE GRADATIONS, AND TWO ASPHALT TYPES ARE USED. CORRELATIONS BETWEEN ASPHALT VISCOSITY, RHEOLOGICAL STRENGTH MODULI, AND DEFORMATIONS OF THE BITUMINOUS MIXES WERE DEVELOPED OVER AN EXTENSIVE RANGE OF LOADING TIMES AND TEMPERATURES. THE APPLICATION OF THE LINEAR VISCOELASTIC THEORY AND THE TIME-TEMPERATURE SUPERPOSITION CONCEPT TO DEFINE THE MECHANICAL PROPERTIES OF ASPHALTIC CONCRETE MIXTURES WAS RIGOROUSLY INVESTIGATED. AN EQUATION OF STATE TO DESCRIBE THE LOAD, DEFORMATION, TIME, AND TEMPERATURE- DEPENDENT BEHAVIOR OF ASPHALT CONCRETE IS PRESENTED. THE AGREEMENT OF THE DATA IN THIS EXPERIMENTATION PROVIDES A VERIFICATION OF THE ABILITY OF THE LINEAR VISCOELASTIC THEORY TO DESCRIBE THE RESPONSE OF ASPHALTIC CONCRETE, AS WELL AS OF THE APPLICATION OF THE DERIVED EQUATIONS OF STATE AND THE TIME-TEMPERATURE SUPERPOSITION CONCEPT TO THESE MATERIALS. /AUTHOR/
