Functional needs, characterized by geometric features and surface characteristics are of paramount importance in ensuring road user comfort and safety. The effects of roughness on vehicle operating and pavement costs are well known. Higher pavement roughness reduces vehicle’s speed, increases wear and tear of vehicles, increases consumption of fuel and lubricants of vehicles. It also increases maintenance cost of vehicles as well as of pavements. Therefore, the roughness of pavement surface is one of the main factors which need immediate attention of field engineers and planners. Functional performance study in terms of roughness is conducted on different road sections of cement concrete pavements.
