APPLICATION OF FRACTURE MECHANICS IN THE ANALYSIS OF PAVEMENT FATIGUE

THE PURPOSE OF THIS PAPER IS TO PREDICT THE FATIGUE LIFE OF PAVING MIXTURES IN TERMS OF MATERIAL CONSTANTS, GEOMETRY, BOUNDARY CONDITIONS, AND THE STATE OF STRESS. FATIGUE IS DEFINED IN TERMS OF CRACK INITIATION, INFLUENCES ON CRACK GROWTH, AND CRITICAL STRESS INTENSITY AT THE CRITICAL FAILURE POINT. CRACK GROWTH PARAMETERS WERE DETERMINED FROM BEAM LOADING EXPERIMENTS. FATIGUE LIFE ESTIMATES BASED ON THESE PARAMETERS AGREED CLOSELY WITH EXPERIMENTALLY DETERMINED VALUES.
