Unsurfaced roads may be permanent or temporary, for example, haul and access roads are normally unsurfaced roads and intended for a relatively short life. But a much larger network of unsurfaced permanent roads exists. In many parts of the world, including many highly developed countries, most connecting roads and farm-to-market roads are unsurfaced. They comprise one or more layers of unbound material to protect the subgrade, distribute wheel loads, and provide a suitable surface for vehicles to travel safely. 

All roads, temporary and permanent, should be designed to provide the required service life, based on traffic load and ride quality, with the most economical use of materials and energy. Economical design should also deliver minimum carbon emissions and the lowest whole-life cost.
