Class A roadstone is the standard base course in Iowa. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts.
That section defines Class A crushed stone and Class B crushed stone to Gradation No.
11, and Class C gravel to Gradation No. 10.
County engineers and city entrance standards call the same material roadstone and write it as Class A roadstone.
Order Class A Roadstone for a drive, a parking pad or a farm lane. Order 1 Inch Roadstone when you want a coarser grade under a finer surface course.
Round river gravel belongs to the Missouri and Mississippi valleys. Iowa is overwhelmingly crushed limestone, so the stone here is crushed limestone.

Ground Conditions Across Cass County
Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a windblown loess mantle. Below that are buried paleosols, including the Yarmouth-Sangamon paleosol, a thick grey clay that water will not move through.
That clay does not take water, so it perches and runs off. Drives go soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.
This is Iowa's most eroded landscape. Streams cut deeply and hillslopes carry a fine texture of rills.
Gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and outlets.
The working season here is the longest in the state. Clay soils still need to dry before anything gets compacted, so a wet spring pushes base work back several weeks.
Cold winters bring repeated freeze-thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
Choosing the Right Material
Shelby County shares this ground. It sits on the Southern Iowa Drift Plain too, so the base and drainage choice there follows the same logic as it does here.
Pottawattamie County is different. Windblown silt runs more than 60 feet deep there, and 150 to 200 feet in places, forming steep ridges along the Missouri valley.
That deep silt drains differently from the clay till under Cass County. Where clay perches water and softens a drive, deep silt needs a stable base course before anything sits on it.
Guthrie County spans more than one zone, reaching from the Southern Iowa Drift Plain into the Des Moines Lobe. The ground changes as you cross it.
