ANALYSIS OF FATIGUE OF PAVING MIXTURES FROM THE FRACTURE MECHANICS VIEWPOINT

THE PAPER DISCUSSES APPLICATION OF FRACTURE MECHANICS TO THE ANALYSIS OF FATIGUE CHARACTERISTICS OF PAVING MIXTURES. A METHOD OF DETERMINATION OF CRACK GROWTH PARAMETERS FOR ASPHALTIC BEAMS RESTING ON ELASTIC FOUNDATION IS PRESENTED. THE FINITE ELEMENT METHOD OF ANALYSIS IS USED FOR THE DETERMINATION OF STRESS INTENSITY FACTORS FOR VARIOUS CRACK SIZES. THE EFFECT OF MATERIAL CHARACTERISTICS, FOUNDATION MODULUS, AND MODE OF LOADING ON THE CRACK GROWTH PROCESS OF ASPHALTIC MIXTURES, IS DISCUSSED. THE EFFECT OF ASPHALT PENETRATION ON THE PARIS CRACK GROWTH LAW IS SHOWN. IT IS ALSO SHOWN THAT FRACTURE MECHANICS PRINCIPLES CAN BE USED TO PREDICT FATIGUE LIFE OF PAVEMENT MATERIAL. /ASTM/
