ANALYTICAL PROCEDURES IN NONDESTRUCTIVE TESTING PAVEMENT EVALUATION

An overview of typical procedures currently used for pavement evaluation using nondestructive testing deflection data is provided, focusing primarily on backcalculation. Some of the more typical problems encountered in these approaches are briefly discussed. Critical issues related to fundamental theoretical assumptions of static loading, as well as material continuity, homogeneity, and elastic behavior, are addressed, particularly in the context of validation of backcalculation results.
