ASTM 57 Stone Specifications | Hunker
Gradation of stone and rock is found by ASTM C136, the Test Method for Sieve Analysis of Fine and Coarse Aggregates. Gage numbers are used to identify aggregate. ASTM No. 57 aggregate is found using a 1.5-inch sieve, through which all of the stones will pass. No ASTM 57 aggregate stone is smaller than a No. 8 seize with a 0.0937-inch sieve.

Substation Grounding: Role of Crushed Rock
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.
