The operating performance of a mine haul road can be subdivided into four distinct design components, and when designing and constructing a haul road for optimal performance, these design components are best addressed using an integrated approach. If one design component is deficient, the other components may not work to their maximum potential and road performance is often compromised. This will most often be seen as ‘maintenance intensive’ or high rolling resistance roads, translating to increased equipment operating, downtime and repair costs. The cure, however, is not necessarily just ‘more frequent maintenance’; no amount of maintenance will fix a poorly-designed road.
