Abstract

The four point bending fatigue tests were carried out for dense graded asphalt mixtures under various wave patterns in repeated loading: sinusoidal, triangular, twin peaks, sinusoidal with one second rest period, sinusoidal with ten second rest period. Analyzing the results using classical fatigue analysis, energy approach and ENTPE fatigue damage approach, it was found 1) that the fatigue damage subjected in asphalt mixtures differs significantly depending on the wave patterns of repeated loading, giving much difference in the number of load applications to failure, 2) that the number of load applications to failure is depending considerably on the rest period 3) that there are linear relations between the rate of stiffness change and the number of load applications to failure, showing approximately constant relations even if loading wave pattern and rest period are different.
