HELLO CIVIL ENGINEERS
The basic components of the highway are the road width, cross slope, pavement, road margins, traffic separators, and curbs. These geometric elements are designed and influenced by the psychology of the driver, the characteristics of the vehicle and the traffic of the region. Highway safety is ensured by fulfilling the management of these elements in a skillful manner.

Cross Slope or Camber
Cross Slope or camber is the slope that is provided in the transverse direction of the pavement or carriageway, as shown in figure-1. 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.

The value of the slope is dependent on the type of materials used for road construction and the amount of rainfall in the region. Generally, the value of cross slope varies from 1 in 60 to 1 in 25.
Carriageway or Pavement
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.
Traffic lane is defined as the carriageway or the pavement that is designed for the movement of one line of traffic. Generally, for single lanes with a maximum width of 2.44m, the width of the lane is desirable to have 3.75m. For the pavements designed to have two or more than two lanes, the width is supposed to be 3.5m.
