Abstract
This invention relates to a process for measuring the dynamic load exerted on a highway by the axles of the vehicles circulating thereon. Two piezo-electric cables sensitive to the pressure of the axles, furnish, upon passage thereof, a weight information pulse and a speed information pulse, respectively. Signals representing respectively the area of the pulse and the duration of the time gap separating the pulses, are applied to a divider which effects the quotient thereof and furnishes a signal representing the dynamic load.
