Survey data have been used to determine the incidence of unequal axle-loading on heavy goods vehicles (HGVs) with close-coupled tandem and tri-axle groups and its estimated affect on pavement damage. The incidence of unequal axle-loading was high in all three groups. Nine commodity groups were analyzed. The magnitude and affect of unequal axle-loading within bogie systems was most significant in three of these, namely bulk materials, bulk liquids and manufactured goods. Unequal axle-loading on tandem axle bogies generally increased with the increasing age of the vehicles sampled. By contrast, unequal axle-loading on tri-axle bogies was greatest on trailers built between 1976 and 1982. Purpose-designed tri-axle vehicles built subsequently seem to have better load-balance between their axles.
