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.

crusher will be located at the quarry or mine with a stockpile of crushed stone being maintained nearby to cover peri-ods when the quarry is not in operation. Primary crushers will normally reduce stone to 1 - 3 inches in size. Secondary crushers are normally used to reduce stone to sizes below one inch. These are usually cone crushers or high-
stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the mixture by weight and 75 to 85 percent by volume.
