Components of road

1. Components of road  CARRAIGE WAY  SHOULDER  CAMBER  CURBS  GRADIENT

2. Carriage way: The paved portion of the highway or the road over which the traffic is meant to move is called the pavement or the carriageway. The pavement width is dependent on the  width of the traffic lanes  and the  number of lanes planned for construction.

3. Shoulders:   These are provided along the road edge . This area serves the purpose of accommodating vehicles that are compelled to be taken out of the pavement or the roadway. These also act as a service lane for the vehicles that have broken down.

4. Camber: camber is the slope that is provided in the transverse direction of the pavement or carriageway. The cross slope helps to drain off the rainwater from the road surface. Inadequate cross slope results in the flooding of water over the pavement, which results in deterioration of the highway.

5. Curb: The boundary between the pavement and the shoulder is called as curbs. Curbs are desirable to be constructed for urban roads.

6. Gradient: It is defined as the rate of rising or falls along the length of the road with respect to the horizontal is known as Gradient of  Road . In another word, it is the longitudinal slope provided to the formation level of the road along its alignment.

7. Purpose of Providing Gradient to the Roads To connect the two stations or points with each other, which are located at different levels. To provide  effective drainage of rainwater,  especially when the  pavement  is provided with the curbs. To construct the side drains economically.
