it is still common to process gravel simply by screening to a maximum top size.A great benefit is gained from processing the material by crushing. This means that a good percentage of the stone will be fractured in the crushing process.The broken stones will embed into the surface of a gravel road much better than rounded, natural-shaped stone.
