Well designed and maintained haul roads are the key to minimizing truck haulage on-road hazards and costs, as well as increasing productivity. However, practically designing and managing a haul road for optimal performance is often difficult to achieve. Poorly designed and built roads exhibit high rolling resistance – a 1% increase in road rolling resistance can typically reduce speed on ramp by as much as 10% – and on the flat by up to 26%.
In the current economic climate, investment and operating decisions come under scrutiny. In the long run, this scrutiny returns improved efficiencies and leaner, healthier operations. The focus of this evolving evaluation process often falls on haulage operations – simply by virtue of their contribution to overall cost of operations – often in excess of 50% of total costs for deep open-pit mines. Whilst the end result – improved efficiency and reduced cost per ton hauled – is not in itself problematic, it is the route, or process followed to achieve these savings that needs to be carefully managed.
The South African design method represents the state of the art in haul truck pavement design. This paper outlines the South African design method:

Caterpillar Haul Road Design and Management
A Presentation by Pete Holman (2006)
Cat Global mining have also published a good presentation by Pete Holman titled Caterpillar Haul Road Design and Management, while in part being a bit of a marketing plug for the exclusive Caterpillar road monitoring tool called “Road Analysis Control” or RAC, presentation contains good detail with respect to road design parameters, tyre management, grade impacts on load transfer for both cross fall and ramp gradients and dust control techniques.
