Camber is the convexity provided on the surface of a highway. It is an important feature of highway design and construction. Camber is the slope provided on the road surface to enable water to drain off the surface and to provide a better grip for vehicles. The following are some details about the camber:

• Definition: Camber is the slope provided on the road surface to enable water to drain off the surface and to provide a better grip for vehicles.

• Purpose: The purpose of providing camber is to ensure that the road surface is sloped in such a way that the water drains off it. This prevents water from pooling on the road and reduces the risk of accidents due to skidding.

• Types of Camber: There are two types of camber: positive camber and negative camber. Positive camber is when the road surface is sloped towards the center of the road, while negative camber is when the road surface is sloped away from the center of the road.

• Factors Affecting Camber: The amount of camber provided on a road depends on various factors such as the type of road, the width of the road, the speed of traffic, the expected volume of traffic, and the terrain.

• Advantages of Camber: The advantages of providing camber on a road surface are that it improves the drainage of water, increases the safety of road users, reduces the risk of accidents due to skidding, and reduces the wear and tear of the road surface.

• Disadvantages of Camber: The disadvantages of providing camber on a road surface are that it can increase the cost of construction, it can make it difficult for cyclists and pedestrians to move on the road, and it can cause discomfort to passengers in vehicles.

In conclusion, camber is an important feature of highway design and construction. It is essential for ensuring the safety of road users and reducing the risk of accidents due to skidding. The amount of camber provided on a road depends on various factors, and it is important to consider all these factors while designing and constructing a road.
