Heavy vehiclesinclude busses, trucks, lorries, trucks with trailers, tractors withsemitrailers.Heavy Goods Vehicle (United Kingdom)Hot Mix Asphalt. This term will be used loosely in this report toinclude all pavement mixes of bitumen and mineral aggregates,regardless of bitumen type or grading and type of the mineralaggregate.

Often, only the vertical forces are considered, butalso longitudinal and lateral horizontal forces can occur, due toacceleration, deceleration, steering, ascent or descent of the vehicleand/or inclination of the pavement.Linear Variable Differential Transformer (type of gauge fordisplacement measurements)million standard axles of 80 kN (UK)= towed axleOpen Asphalt Concrete (NL, type of HMA for binder courses)Organisation for Economic Co-operation and Developmentversion 29 November 2001
