Effect of Fatigue Cyclic Loading on the Linear Viscoelastic Properties of Bituminous Mixtures

Nguyen, Quang Tuan / Di Benedetto, Herve / Sauzeat, Cedric

This paper focuses on the three-dimensional (3D) linear viscoelastic (LVE) behavior of bituminous mixtures and the damage occurring after a great number of cyclic loadings. Two complex modulus tests were carried out before and after a fatigue test. The complex modulus $E^{*}$ and complex Poisson’s ratio $ν^{*}$ were measured for large ranges of temperatures (from $- 25$ to 30°C) and frequencies (from 0.03 to 10Hz). First, it is shown that the time temperature superposition principle (TTSP) is verified and applicable in the 3D case. Then, the change of the complex modulus created by fatigue test was analyzed. Lastly, a model with a continuum spectrum called two springs, two parabolic elements, one dashpot (2S2P1D), developed at the Ecole Nationale des Travaux Publics de l’Etat (ENTPE), was used to simulate the 3D linear viscoelastic behavior of the tested bituminous mixture before and after fatigue damage.
