Following are the difference between flexible pavements and rigid pavements such as :
Rigid pavements and Flexible pavements
|The earthen, gravel, water bound macadam and bituminous roads are known as flexible pavement.
||Cement concrete roads are known as rigid pavement.
|Inflexible pavement the top surface takes the shape of the subsurface soil e.g. W.B.M road
||The rigid pavement has more stiffness and capacity to bridge over loose soil pockets in the sub-grade e.g. Concrete roads.
|Due to flexibility, there are ups and downs on W.B.M. roads and bituminous roads WBM. Water bound macadam.
||Due to more stiffness and thickness, there are no ups and downs on concrete roads
