The study of the off-road vehicle traffic consists in estimating the drawbar pull of a vehicle on a given soil and can be calculated by means of such models as that of Janosi-Hanamoto which depends on the soil mechanic parameters, i.e., the angle of friction and cohesion. These parameters result generally from shearing tests. The annular shearing test is often used to estimate the soil shearing in mobility studies. Other shearing test is the translation shearing test which consists in the translation, at a constant speed, of a loaded plate with a smooth interface or with grousers. This article aims to present the validation of the translation shearing test for the study of the shearing of the granular surface soils and the method allowing us to link this operational test with the efforts measured during full-scale tests. An experimental device was developed to perform superficial translation shearing tests of a loaded plate at slow speed or fast speed to obtain the shearing forces.
