Types of road

A road is a thoroughfare, route, or way on land between two places that has been surfaced or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse. Roads have been adapted to a large range of structures and types in order to achieve a common goal of transportation under a large and wide range of conditions. The specific purpose, mode of transport, material^[1]^[2] and location of a road determine the characteristics it must have in order to maximize its usefulness. Following is one classification scheme.

Taxonomy of Road

Marohn distinguishes between roads that are designed for mobility which he terms "roads" and those that function to "build a place", build community wealth and provide access to land. He argues the value of a road in terms of both community wealth and mobility is maximised when the road speed is either low or high, but not at midpoints such as 45mph. He refers to this low-value midpoint of speed and land access as a stroad.^[3]^: 69

Material type

Roads also may be classified based on their pavement material types. For instance, the Long-Term Pavement Performance database includes more than 30 types of pavement types for roads in the US and Canada.^[2]^[4]^[5] However, a more generic classification of roads based on material type is as follows.^[5]^[6]

Concrete roads

Earthen roads^[7]
Murrum roads
Kankar roads
Bituminous roads^[8]
