Abstract

See full text

A method for characterizing k mechanical parameters of a pavement formed by a stack in a direction Z of N layers, including: a) applying a load to the pavement to deform the pavement; b) in response, measuring deformation of the pavement at various points with displacement sensors situated at each of the points; c) determining the k parameters on the basis of the measurements of the various sensors. The measuring b) is carried out by at least k sensors buried inside the pavement and distributed in at least two non-parallel directions X and Y perpendicular to the direction Z, and the c) determining of the k parameters is obtained on the basis of known boundary conditions on lateral edges of the pavement.
