  • To estimate the fatigue life of asphalt mixture during the cracking initiation of asphalt pavement, its true stress and strain loop curve was established by direct tension test based on partial stress and strain theory, its nominal stress and strain were converted into partial stress and strain through Neuber equation, and its loop curve and Neuber equation were modified in order to meet the question of plain stress.The fatigue equation of asphalt mixture was established by isostrain fatigue test, and an estimating method of fatigue life was put forward.It is pointed that the fatigue damage of asphalt mixture can be reasonably calculated by its strain fatigue life curve, and its fatigue life during the cracking initiation of asphalt pavement can be estimated by its cumulation damage.
