A unique portable electronic scale for weighing each wheel of highway vehicles moving at speeds up to 70 mph has been developed at the Center for Highway Research, The University of Texas at Austin. The scale consists of a pair of special strain gage transducers, each of which is approximately 54 by 20 inches in plan dimensions and about 2-inches thick, connected to conventional electronic recording equipment. The transducers are set side by side in a traffic lane and flush with the pavement surface. Output signals are not affected by tractive forces, tire contact pressure or area, position of the load on the transducer, temperature, nor moisture. Installation of the scale at a new site requires about 4 hours but installation at a previously occupied site takes only 45 minutes. (BPR abstract)
