Classification or Types of Roads and Their Details

Concrete Roads. Cement concrete is used to construct the pavements in case of concrete roads. These are very popular and costlier than all other types of roads. They are not flexible so they require less maintenance. Concrete roads are suitable for high traffic areas. Concrete roads are laid with joints and time of construction is more.
