Class A roadstone is the base most drives and pads here are built on, and it is the material Iowa calls road rock.

Class A roadstone is 3/4 inch crushed limestone with the fines left in, so it binds and compacts.
11. County engineers and city entrance standards call the same material roadstone.
Order it for driveways, parking pads, shed bases and farm lanes. Class A Roadstone is the standard base course for all of those.
A coarser 1 Inch Roadstone goes under a finer surface course on a new drive, a soft spot, or a lane that carries heavy equipment.
Ground conditions across Jasper County
Jasper County sits on the Southern Iowa Drift Plain, where old pre-Illinoian till lies under a windblown loess mantle. That cover usually runs 5 to 30 feet thick, with buried paleosols beneath it.
The Yarmouth-Sangamon paleosol is a thick, gummy grey clay that water will not move through.
One practical result is that ground drains at the surface while the clay subsoil holds water. It perches, runs off, and leaves drives soft at the bottom of a grade.
Spring rain on saturated clay is the worst of it, so plan base work around a wet spring.
This is also Iowa's most eroded landscape. Streams cut deeply and hillslopes carry a fine texture of rills, and gully and stream bank erosion after heavy rain puts rock on slopes and at outlets.
Plan a clean, open graded stone for drainage and riprap for banks.
Cold winters bring repeated freeze-thaw, and gravel drives and lanes heave every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.

Choosing the right material
Ground conditions change what a base or drainage layer has to do, so it helps to know how the ground around Jasper County differs. Marshall County sits on the Iowan Surface, where loamy glacial till was planed down by cold-climate erosion.
Its loess cover is thin and patchy, with a residual stone line or pebble band near the surface.
That shallow, stony ground takes a different approach than Jasper County's deep loess over gumbo clay. Where the subsoil will not take water, drainage stone carries it away; where limestone bedrock is shallow, a base course sits closer to rock.
Story County and Polk County both lie on the Des Moines Lobe, so their ground matches each other and not this county.
The Dows Formation there is thick, compact pebbly loam till, and the moraine ridges are hummocky and stony. If you are working in Jasper County, the material choice follows the clay and the grade, not the neighbour's ground.
