Jg. Marsh et Rj. Jewell, INSTRUMENTATION FOR A WEIGH-IN-MOTION SYSTEM USING PAVEMENT STRAIN, ASTM geotechnical testing journal, 17(4), 1994, pp. 497-504
A line of vertical strain transducers installed at a depth of 500 mm i
n 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 transd
