AbstractThe objective of the paper is evaluation of the fatigue strength of pavement structure considering the effects of load velocity and temperature variations. The analysis was performed in a wide range of time-temperature operating conditions. The Huet-Sayegh visco-elastic model was used in order to describe rheological properties of pavement asphaltic layers. The identification procedure of the asphalt mixture rheological model was based only on the stiffness moduli results by applying the method described in previous paper of the authors . Consequently, the stress and strain states were determined under various load conditions by using VEROAD software. Finally, the fatigue strength of certain pavement structure subjected to different time-temperature operating conditions was calculated applying two mechanistic empirical methods.
