Bulk Gravel and Aggregate Delivery in Wyoming

What do you order for a drive, a pad or a lane on Wyoming ground? Bulk gravel and aggregate delivery across Wyoming starts with crushed base, the material this state calls the standard base course.

Wyoming Rock Supply sells it by the ton and delivers it. The ground under it decides the rest: bentonitic gumbo clay swells when it takes up water and shrinks when it dries, and it cracks slabs, walls and pavement built on it without mitigation.

Crushed base is the base course for driveways, shop and shed pads, parking areas and county-style lanes.

Those gradings are lettered J, GR, L, K and W rather than numbered. Grading W is the common one-inch-top-size base and Grading GR is the 3/4 inch gradation.

City and county work is usually written against Section 02190 of the Wyoming Public Works Standard Specifications, which uses the same letters and states that base shall be crushed base unless otherwise specified.

Pit run is unprocessed pit gravel, a separate pay item from crusher run in both spec books. Order it for deep fill, raising grade and sub-base under a crushed base course, not as a finished driving surface.

Above the base, the choice is size and shape. Driveway Gravel surfaces a drive or a ranch lane.

Scoria, the red burnt-coal clinker dug in the Powder River Basin, goes on paths, walkways, drives and pads where sound natural aggregate is scarce.

Washed Rock is clean drainage rock for perimeter and curtain drains, foundation drains and downspout runs. 3/4" Crushed Stone handles drainage beds, pipe bedding and construction entrances.

3/8" Crushed Stone covers fine drainage and trench bedding.

Wind River Rock is rounded river-washed stone for decorative beds, borders and dry creek beds. Large River Rock takes dry creek beds and splash pads under downspouts.

RipRap armors stream banks, culvert outlets and slopes against spring runoff.

Sand and soil finish the job. Mason Sand serves brick and block work and paver joints.

Washed Sand levels and beds under flatwork and pavers. Top Soil and Garden Soil cover lawns, grading and raised beds over thin, stony or alkaline native ground.

Ground and Climate Across Wyoming

Wyoming is a set of high basins between mountain ranges, and the ground changes with the basin. The High Plains carry silty wind-laid soils over soft Tertiary sandstone and siltstone.

The Powder River and Bighorn basins are floored with bentonitic gumbo clay weathered off Cretaceous shale, cut by badlands, with red clinker ridges where coal seams burned out.

The Green River Basin and Red Desert are cold high desert with alkaline and saline ground and dune fields. The sound sand and gravel sits on river terraces along the North Platte, Bighorn, Wind, Green and Snake.

Water drives the design. Snowmelt comes off the ranges through late spring, cloudburst thunderstorms fall on hard dry ground, and bentonitic clay subgrades shed water instead of taking it in.

Wet gumbo goes greasy and loses bearing; dry gumbo cracks open.

Wind comes first on erosion. The state climate office puts Wyoming first in the nation for annual average wind speed, and open, dry, thinly vegetated ground blows.

After that come gully and rill cutting in shale badlands and draws, bank scour at spring high water, and fast runoff off burned slopes.

The working season is short. The freeze-free period in the main farmed valleys averages about 125 days and is far shorter at elevation, so base, driveway and paver work runs from spring breakup into autumn, and frozen ground stops compaction through the winter.

Wyoming publishes no single statewide frost depth, and there is no mandatory statewide building code. The State Fire Marshal adopts the residential code and qualified cities and counties adopt and enforce it, so each jurisdiction sets its own figure.

Published local figures run from 34 inches at Jackson and in Teton County, through 36 inches at Cheyenne and Casper, to 42 inches at Douglas, Gillette and Wright. Ask the local building department before setting footing depth.
