A foot of base for sure on a driveway, but don't use a foot of 5/8 or 3/4. Start with 2 inch crusher, or even 2" recycled concrete. When you get 8-10 inches in, switch to 1" or 3/4". We use 1/2 inch galv. pipe for screed guides. Screed the 1", tamp one more time, then use the same pipe for screeding the sand.
Impact crushers are commonly used to crush rocks with a silica contain under 5% such as coal, limestone, and phosphate. The only reason why you would use an impact mill/crusher or a hammer mill on a high-silica rock is because it might be sticky in nature and rich in clay.
The following comparison between the respective feed and discharge areas of a 48 in. gyratory and a 48 in. x 60 in. jaw crusher serves to illustrate some of the foregoing factors: Feed area: Jaw crusher…..one opening of 20 sq. ft Gyratory…..two openings each of 43-4 sq. ft Discharge area: Jaw crusher…..3*1 sq. ft Gyratory…..10-9 …

Application of crushed rock is a means of controlling step voltage and touch voltage. Step Voltage: During a fault condition, a person walking on the surface of substation can experience a voltage potential between his two feet (typically assumed to be 3.3ft or 1m apart). This causes a current to flow from one feet-through his body- to other feet.
