The acquisition of truck axle and gross weight information is necessary for determining structural and maintenance requirements of bridges and pavements and is important also for planning, economic and safety surveys. A system is described using traffic sensors and strain gages on instrumented highway bridge girders to survey axle and gross weights of passing vehicles. Trucks are weighed in motion while moving at normal highway speeds and are undetected by the drivers. A derived weight prediction algorithm filters out the dynamic components of bridge response and obtains the equivalent static axle weights by at least square error minimization. Accurate predictions require the truck dimensions and velocity obtained from traffic sensors. A preliminary system was designed and tested by recording data on analog recorders for subsequent processing. The results indicated the feasibility of this method. A final system was designed, tested and delivered to the Federal Highway Administration. It uses signal conditioners and a mini-computer. Data is recorded in the field on magnetic tape for subsequent truck weight processing on a digital computer. A final test of the system showed repeatability of predictions of both gross truck weight and tandem axles.
