FULL-SCALE PAVEMENT TESTING IN SOUTH AFRICA

The use of data generated by four heavy vehicle simulators (hvs) for testing pavements in South Africa has resulted in estimated savings in highway construction and maintenance costs of 15-20 per cent. The hvs is described as a mobile facility designed to apply the equivalent of 20 years traffic load in a few months to any test section. Either a single - or a dual-wheel load can be employed to apply loads up to 100 kn at speeds of up to 14 km/h. Used on flexible and rigid pavements, the hvs equipment has carried out work on the introduction of cost-effective pavement design, material performance and the influence of moisture in granular materials. As well as design benefits, it is considered that hvs testing has aided construction pratice in South Africa where it has also been tested on recycled asphalt and concrete block pavements. (TRRL)
