摘要: Abstract This research was conducted to evaluate the effect of different loading combinations on permanent deformation behaviour in asphalt mixtures. Therefore, repeated test performed considering stress levels, durations, rest periods and testing temperatures. The results showed that slope coefficient Power-law model has a more influence compared intercept. Moreover, rutting zones are sensitive parameters. Rest period could significantly affect first zone. Nevertheless, secondary zone depends duration deviator stress. Eventually, temperature greatest behaviour.
