Method Of Providing Camber 

The required camber is provide to the subgrade.for providing the desired amount and shape of camber,templates or camber boards are prepared with the specified camber.the material to be used in the subgrade is spread and hand paced to the shape of the desired camber.

The rolling is then started from the edge towards the center.
Then checking of the top surface is done with the help of templates or camber boards.the deficiency by spreading or removing the material as required.
