THE FUNCTIONAL DESIGN OF SURFACE MINE HAUL ROADS

unpaved road defects McInnes9 introduced the concept of wearing course trafficability in which a number of ideal requirements were alluded to Building on and updating this approach, an ideal wearing course for mine haul road construction can also be considered by modifying public unpaved road.

Selection, performance and economic T evaluation of dust

operational defects of wet slipperiness, dustiness, tyre , dust that will be emitted from an unpaved haul road is a function of two basic factors (ARRB, 1996): the erodibility of the wearing course the erosivity of the actions to which the wearing course is subjected.

Dirt road

A dirt road or track is a type of unpaved road made from the native material of the land surface through which it passes, known to highway engineers as subgrade material Dirt roads are suitable for vehicles; a narrower path for pedestrians, animals, and possibly small vehicles would be called a dirt track—the distinction is not well-defined.
