     in any surface mining operations, transportation of ore and waste materials is accomplished on the roads which have been empirically designed and relying strongly on local experiences. considering the direct relationship between mine haul road wearing course and vehicles, functional design of mine haul roads, which relates to the selection of appropriate wearing course materials, plays an important role in the efficiency of the hauling operation, because inadequate design will reduce safety and operational efficiency and will increase costs of maintaining both vehicles and roads. with the aim of investigating the wearing course materials of chadormalu mine haul roads, laboratory tests were carried out to find out the engineering and geotechnical characteristics of these materials. considering the lack of material selection guidelines for mine haul road wearing course material in iran, the determined results of the foregoing tests were compared with the given guidelines in south africa, which are based on the engineering characteristics, identification and classification of functional defects. with the aid of those guidelines and visual assessment of chadormalu mine haul roads, functional defects of used materials were identified. finally, concerning the tests results and recognition of functional defects of haul roads, adequacy or inadequacy of wearing course materials was investigated.
