Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water …
Gravel is often made from crushed rock. Gravel known as size #1 is relatively large. Typically, this gravel ranges in diameter from 2.5 inches (6.35 centimeters) to 4 inches (10.16 centimeters). It can be difficult to work with, as it generally cannot be shoveled and instead must be moved individually, stone by stone.

There will be very little current in the crushed rock; hence, surface voltage (step and touch potentials) will be negligible. For purposes of standardization, a common surface material is #57 crushed granite. This includes stones commonly in the range of ¾ to 1 inch. Much larger stones can simply pose a hazard to walking.
For proper placement and compaction, the asphalt lift thickness should be at least 2.5 to 3.0 times the maximum particle diameter. HL 3 aggregates have a nominal maximum size of 13.2 mm, requiring a minimum mat thickness of at least 35 mm. HL 4 is a slightly coarser mix with aggregates of a nominal maximum size of 16 mm, and hence requiring a ...
A common surface material is the #57 crushed granite which has stones mostly in sizes from 3/4 inch to 1 inch is shown in the picture. Another advantage of having a layer of crushed rock as surface material is that spacing of ground grid conductors (buried beneath the soil) can possibly be increased (saving copper) to meet the same step and ...
