The fatigue of a flexible pavement is highly dependent on the number of axle load. The load of the single axle is different than the multiple axles. Trucks and large aircrafts are major consumer of the pavement structure because they apply the highest loads to the road surface. All heavy vehicles, however, do not cause equal damage because of variations in wheel load (static and dynamic), number and location of axles, and other factors. The mastery of the fatigue behaviour of pavements subjected to the great strains, under tandem axles, permits to follow the development of technology and increases the performance of projects. The purpose of the experimental study presented in this paper is to improve the knowledge of the fatigue response of pavement material under the repetition of such specific loadings. Several phenomena are coupled due to the material viscoelasticity: effects of the type of loading (sine and tandem), effects of the shape of the tandem signal. The objective is to identify the laws of fatigue behaviour under tandem loading and their comparison with the conventional loading (classical sine). The results are presented and discussed.
