Abstract

A line of vertical strain transducers installed at a depth of 500 mm in a dense sand subgrade across one wheel path of the left hand lane of a busy highway was used to measure vehicle weights. The strain transducers, the custom-made LVDTs they incorporate, the method of installation, and the data acquisition system are described.
