APPLICATION OF FRACTURE MECHANICS FOR IMPROVED DESIGN OF BITUMINOUS CONCRETE VOLUME 1. PLAN OF RESEARCH, STATE-OF-THE-ART, AND MATHEMATICAL INVESTIGATIONS

In this study, the State-of-the-Art of fatigue and fracture concepts and mathematical developments of stress-intensity factor were reviewed. The interrelation between normalized stress-intensity factor crack length and beam on elastic foundation are discussed. The effect of material constituents influencing the fatigue and fracture response of asphaltic mixtures are discussed. The sensitivity analysis included the effect of mixture constituents such as asphalt, filler and polymeric and fibrous additives. In this study, a number of fatigue models for asphaltic concrete were also investigated. In this volume, the State-of-the-Art of fatigue and fracture concepts and mathematical development of stress-intensity factor are reviewed. The mathematical relation between the normalized stress-intensity factor, crack length and beam on elastic foundation geometry are presented. Nomographs are developed to aid in solution of stress-intensity variation with crack length. The limits of analysis and restriction of the theory are discussed. Typical examples demonstrating the applicability of concepts developed are presented. /FHWA/
