Haul Road Design
The following papers contain general information on the design and construction of mine haul roads, both are good general reference and design assistance tools that can be adapted to most operations.
Design of Surface Mine Haulage Roads – A Manual
A Paper by Walter W. Kaufman and James C. Ault
This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road
design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
Traffic control and design of proper lane widths to promote safe vehicle movement are included, as are suggested criteria
for road and vehicle maintenance and for runaway vehicle safety provisions. The aim of this publication is to provide
those involved with surface mine haulage road design with a complete manual of recommended practices that, if
implemented, will promote safer, more efficient haulage routes.

DESIGNING AND MANAGING UNPAVED OPENCAST MINE HAUL ROADS FOR OPTIMUM PERFORMANCE
SME Paper by R. J. Thompson and A. T. Visser
The expansion of surface mining has led to the development of very large off-highway trucks currently capable of hauling payloads in excess of 290t. Mine haul roads have historically been designed empirically, relying heavily on local experience; the trend in increasing truck size will thus render the current pavement systems inadequate. Since truck haulage costs can account for 10%-50% of the total costs incurred by a surface mine, not only would the maintenance costs of existing roads of inadequate design increase, vehicle operating and maintenance
costs would also increase prohibitively. There is thus a need for improved design technologies encompassing the construction and
management techniques of mine haul roads, appropriate for the wheel loads of vehicles now in use.
The aim of the paper is to present the different components of a mine haul road design and management system and to demonstrate the value of its application through case studies. The system has been applied at several South-African surface mines and distinct benefits have been derived. The improved structural design of a new road resulted in a 29% saving in construction costs and also provided better service, whilst the optimal selection and management of wearing-course materials provided better functionality at lower total transportation operating costs.

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.
