Abstract

L'invention concerne un procédé de mesure des paramètres de déflexion des chaussées. On fait circuler à vitesse constante un véhicule, le long de la chaussée à mesurer, et on applique périodiquement sur la chaussée au moins un capteur de mesure de déformation à une position fixe pendant une certaine durée malgré l'avance du véhicule. On applique périodiquement au début de la durée pendant laquelle le ou les capteur(s) reste(nt) posé(s) immobile(s) sur le sol, un impact quasi-instantané sur la chaussée à une certaine distance du ou des capteurs. On détecte au moyen du ou des capteurs les déformations engendrées par cet impact, en vue d'en déduire des paramètres de déflexion de la chaussée. Application : étude de l'état des routes.
