About #1 stone
#1 stone is large crushed stone, from about 1.5 up to 3.5 inches across. It is laid as a thick pad at a job entrance, in a creek crossing, or over ground too soft for anything smaller. A pad of it is usually 6 to 12 inches thick.
More about #1 stone
The standard chart has #1 passing a 4 inch screen, with most pieces between 3.5 and 1.5 inches. Some suppliers sell it as 3 inch clean, and erosion plans often name it for site entrances.
Many state erosion control rules ask for an entrance pad at least 6 inches thick, about 50 feet long and as wide as the gate, laid over fabric. The large pieces shake mud loose from tires, and the gaps hold that mud until the pad is scraped or topped up.
In a low-water crossing it is heavy enough to stay put in an ordinary storm, though a flood can still move it. Spread it with a dozer or an excavator bucket and walk the tracks over it; nothing short of a heavy roller will seat it. A wet load weighs almost exactly what a dry one does, because water cannot cling to stone this coarse. Check with the county before you put stone in a live stream, because work in the water often needs a permit.
