VERIFICATION OF FRACTURE MECHANICS CONCEPTS TO PREDICT CRACKING OF FLEXIBLE PAVEMENTS
A REVIEW OF THE STATE OF ART OF APPLICATION OF FRACTURE MECHANICS CONCEPTS TO THE PREDICTION OF FATIGUE CRACKING OF BITUMINOUS MIXTURES IS PRESENTED. THE BASIC PRINCIPLES OF FRACTURE MECHANICS AND THE METHODS OF ANALYSIS OF CRACKED PLATES RESTING ON ELASTIC FOUNDATION ARE DISCUSSED. ANALYTICAL AND EXPERIMENTAL METHODS OF DETERMINATION OF STRESS-INTENSITY FACTOR FOR TWO-DIMENSIONAL AND THREE-DIMENSIONAL SYSTEMS USING PLATE BENDING ANALYSIS, FINITE ELEMENT AND BOUNDARY COLLOCATION PROGRAMS ARE PRESENTED. THE EXPERIMENTAL RESULTS INDICATE THAT THE CRACKING PROPAGATION PROCESS OF ASPHALTIC MIXTURES CAN BE PREDICTED USING THE POWER LAW RELATION BETWEEN THE CRACK GROWTH RATE AND THE STRESS-INTENSITY FACTOR. A FRAMEWORK FOR THE RATIONAL METHOD OF ANALYSIS OF PAVEMENT FATIGUE USING FRACTURE MECHANICS PRINCIPLES IS PRESENTED. AVAILABLE EXPERIMENTAL DATA ON FULL-SCALE PAVEMENT IS USED TO SHOW THE APPLICABILITY OF THE CONCEPTS DEVELOPED TO THE ANALYSIS OF IN-SERVICE PAVEMENT STRUCTURES. /DOT/
