Surface mining industry association the Aggregate and Sand Producers Association of Southern Africa (Aspasa) has partnered with the Committee of Transport Officials (Coto) and other role-players to hammer out standards for different types of materials to be used on South African roads. This led to quarrymen and miners of materials used in the construction of roads having a new set of specification to be followed in order to supply national and provincial roads agencies, as well as all metros and municipalities with road construction materials.
