PERMANENT DEFORMATIONS OBSERVED IN THE LABORATORY AND ON EXPERIMENTAL ROADS

DEFORMATIONS PERMANENTES OBSERVEES EN LABORATOIRE ET SUR ROUTES EXPERIMENTALES

Arising from studies into permanent deformation under repeated loading, an empirical law was established, which may be used to estimate depth of grooves. A full scale experimental test of this method of estimation was carried out successfully. A generalisation of the deformation law according to the concept of dissipation energy is proposed and experimentally checked. In order to estimate the resistance to groove formation of 12 mixes on an experimental road, laboratory tests were carried out in accordance with three methods. The measured mechanical properties were compared with tracking groove depths which arose after five years in operation. (TRRL)
