DEVELOPMENTS IN MINE HAUL-ROAD DESIGN

This article presents current knowledge in the field of haul-road design, points out some of its defects, and introduces a new total design strategy. Current haul-road design methods are predominantly empirical, and include: (1) the California Bearing Ratio (CBR) structural design method; and (2) mechanistic structural design methods, which promote efficient and cost-effective designs. The functional trafficability of the pavement is as important as the design's structural strength. Nine major functional defects are listed, which have been reported in work on mine haul-road design. A total pavement design strategy should contain structural, functional, and maintenance components, which contribute to overall pavement performance. They reduce haulage and maintenance costs by applying highly specific designs, based on a portable general design and operation optimisation. There are functional guidelines on gravel selection for the wearing course, based on research conducted on public roads. The maintenance management system used for public roads, which uses economic criteria for scheduling maintenance, can be applied in the mining haul-road environment.
