A METHOD FOR ASSESSING ADEQUACY OF ROAD PAVEMENT STRUCTURES USING A HEAVY VEHICLE SIMULATOR

The heavy vehicle simulator is a unique, mobile linear tracking machine for subjecting roads to accelerated trafficking. This paper describes the system which was developed to ensure that the heavy vehicle simulator is used to its maximum benefit at minimum cost. It is necessary to provide adequate staff to run the system as well as to provide adequate ancillary equipment. Equipment includes good communication systems as well as systems which are used to measure the behaviour of the pavement. There are currently four hvs machines operating in South Africa. One belongs to the Department of Transport, one to the Transvaal Roads Department and two to the National Institute for Transport and Road Research. It has been possible to apply some 150 million equivalent 80 kn axle loads to roads in South Africa during the past two years with the Department of Transport's hvs alone. Significant savings of between $30 million to $80 million per annum can and are being achieved with this system, primarily as a result of increased confidence in the reduction in pavement thicknesses. Other major advances include the early identification of problems which are experienced with roads, and the fact that new materials can now be used with confidence. (TRRL)
