The University of Pretoria (Republic of South Africa) presents improved haul road design and management techniques which have been developed specifically for the bulk materials transport operations on South African surface mines. To realise a reduction in haulage and road maintenance costs, these developments are combined into an integrated design strategy combining mine layout, construction techniques, available material and road maintenance equipment with the choice of modern ultra-heavy haul trucks. To improve the structural strength of the pavement a new mechanistic structural design methodology is presented. Based on both road-user acceptability criteria and models of functional defect progression the optimum wearing course material is selected. The maintenance management system model is an aid in identifying the most appropriate haul road maintenance schedule commensurate with minimum total road-user cost.
