NONLINEAR CHARACTERIZATION OF SAND-ASPHALT CONCRETE BY MEANS OF PERMANENT-MEMORY NORMS

EXPERIMENTAL AND THEORETICAL INVESTIGATIONS DEMONSTRATE THAT EXTENDED NONLINEAR HOMOGENEOUS CONSTITUTIVE EQUATIONS USING LEBESGUE NORMS ARE READILY APPLICABLE TO DEFINING THE MECHANICAL BEHAVIOR OF SAND-ASPHALT CONCRETE. AN EQUATION DEVELOPED BY FARRIS AND FITZGERALD WHICH ACCOUNTA FOR THE MAXIMUM STRAIN EVER IMPOSED UPON A MATERIAL AS WELL AS A WEIGHTED AVERAGE OF THE STRAIN HISTORY IS EMPLOYED. THE THEORY OF LINEAR VISCOELASTICITY, OFTEN USED FOR DETERMINING THE STRESSES AND STRAINS IN ASPHALT PAVEMENTS DUE TO WHEEL LOADS, IS SHOWN TO BE INADEQUATE FOR CHARACTERIZING MATERIALS WITH ASPHALT BINDER UNDER REPEATED LOADS. /DOT/
