Description
Short technical description: Field measurement of the residual bearing capacity of a flexible pavement (dynamic measurement every 5 m, at a speed of 18 km/h). The device consists of a lorry with a very long frame, the rear axle of which is loaded to weigh 13 t (this can be reduced to 8 t). Every 5 m, a sensor attached to a caterpillar measures the temporary deflection of the pavement when the rear axle is passing over. The deflection bowl is measured over a length of 4 m. Precision of measurement: 0.02 mm. Méthod of measurement: CME 54.26 (catalogue of measurements of the Walloon Region of Belgium). Unique features: http://www.brrc.be Relevant standards: Mesure de la déflexion engendrée par une charge roulante. Détermination de la déflexion et du rayon de courbure avec le curviamètre, norme française, NF P 98-200-7, décembre 1997. Chapitre 54 du Catalogue des Méthodes d’Essais, annexe au Cahier de Charges Type du Ministère de la Région wallonne, version 2002. Construction date: 1994 Specified type of facility: Pavement condition
