Method for measuring dynamic loads applied to a carriageway by road traffic

摘要

The invention relates to a method for measuring dynamic load exerted on a carriageway 3 by the axles of the vehicles which travel on it. Two piezoelectric cables 1, 2 which are sensitive to the pressure of the axles supply, when they pass, respectively a weight data pulse C4 and a speed data pulse C1. Signals C8, C9 representing respectively the area of the pulse C4 and the duration of the time interval ti-to separating the pulses C1, C4, are applied to a divider 17 which takes the quotient and supplies a signal C10 representing the dynamic load. <IMAGE>
