What is a Road Camber?
Roads aren't flat, but they were designed and built to aid in the draining of water. This is referred to as the cambered road. The surface is tilted to prevent rainwater and snow melt from accumulating into Puddles. The surface water of a road can cause aquaplaning when a vehicle's wheels are removed off the asphalt when moving. This loss of grip , traction and grip can result in a loss of control. It is extremely hazardous and scary. If water accumulates and doesn't drain away, it will ruin the surface with potholes and cracks becoming apparent over time, particularly when it is frozen.
Different Types of Road Camber?
The majority of routes in UK are inclined by the "A type" camber. This is the place where your central point lies situated at its highest, and where it is set on the kerb. This point, which is central to the kerb referred to as the crown. The surface water is pumped to the gullies on the edges, and then pumped to an urban drain system. The effect on driving when using the camber will be that its effect on your steering is greater when you make the left hand side of the turn, but decreases when you make a right-hand turn.
The tracks for racing motors and high-speed roads differ in that they feature the "Elevated Camber". This is when all of the roadway is banked towards the edge of the bend. The effect is to aid drainage, but also lessen the force centrifugal the vehicle is subjected to when it turns at high speeds.
Another type is the adverse road camber. It is a situation where the road slopes downwards toward the outside, and is in contrast to the banked corner. Sometimes, we see this happen when road construction is taking place and the contraflow is being constructed.

Protection of Road Cambers with BituChem
Bituchem offer a variety of road maintenance and highway waterproofing products that protect the top layer the surface. When coupled with the camber of roads, the excess water flows off and is distributed making the road an easier place to travel over. It also improves the durability of the surface.
Advantages Of Camber
1. Camber allows for quick drainage of rainwater, which helps to protect the foundation of the road from being weakened due to the percolation of rainwater into the road's surface.
2. This keeps rainwater from collecting in the local depressions or shrinkages and creating pooling of rainwater on road's surface, which is a nuisance to both the public as well as the road's structure.

Method Of Providing Camber
In general, camber is made available on straight roads by elevating in the middle of the road in relation toward the sides, creating the crown, or the most prominent point along the centerline.
In horizontal curves that have superelevation, surface drainage is affected because it raises the exterior part of the roadway in relation toward the interior edge and allowing an appropriate superelevation.
Camber's rate, also known as cross slope is normally calculated by 1 in "n" which signifies that your transverse slope will be a ratio of 1 . vertical to "n" horizontal. Camber is also measured in percentage. If the camber is x percent and the cross slope is 100x.
Method of Camber Construction
Once the appropriate quality of camber is calculated, it is placed on the pavement of the highway.
First , templates or camber boards are made using the camber needed.
Then, the subgrade material to be used as the subgrade is spread and moved until the desired shape for the camber has been created.
It is the process by which rolling is done. It is essential to ensure that the rolling process is carried out from the edges toward the center.
When the rolling process is finished The top surface is examined by means of templates and camber boards.
The excess material is taken out in the case excess, and the additional material is distributed in the event there is a deficiency in material.
