This paper describes a new highway scale that records a vehicle's weight and many other particulars such as the distance between axles with the vehicles travelling at speeds up to 10 Km/h. Using information gathered from the scale, highway planners can predict the life of a road and plan highway and bridge construction more realistically. Information gathered from the scale may also be used to develop new highway regulations such as weight restrictions for trucks. This scale is the only one tested by Transport Canada's Research and Development Agency that did not deteriorate during tests in different kinds of weather. The scale is a wafer-like platform embedded in the pavement level with the surface of the highway and is depressed only the thickness of a piece of paper by traffic over it. When vehicles pass over the scale, sensors just below the surface send impulses throught underground wires to a computer in a trader beside the highway; and the characteristics of each vehicle are stored on magnetic tape. No one needs to work at the site. The computer works 24 hours a day recording the speed, date, time of day and lane number of each vehicle, as well as the number of axles, inter-axles distance, weight of each axle, and gross weight.
