Class A roadstone is the base course most Iowa drives are built on. It is crushed limestone with the fines left in, so it binds and compacts under a vehicle.

Ground and Conditions in Mount Union

Mount Union sits on the Southern Iowa Drift Plain, where old till lies under a windblown loess mantle. Beneath that, a thick grey clay paleosol stops water from moving down.

Water perches on that clay instead of soaking away. On rolling ground it runs off and leaves the bottom of a grade soft, and spring rain on saturated clay is the worst of it.

A thin base shows that failure first. The stone punches down into the soft spot and the surface ruts, so the repair is more roadstone rather than a different material.

This is Iowa's most eroded landscape, with deep stream cuts and gullies after heavy rain. That is why rock goes on slopes, culvert outlets and stream banks here.

Clay soils also need to dry before anything gets compacted. A wet spring can push base work back several weeks, even though southern Iowa has the longest working season in the state.

Cold winters bring repeated freeze and thaw, which heaves gravel drives and lanes every spring. Frost depth is commonly 42 inches in this part of Iowa, and the local building official sets footing depth.

Materials for Mount Union Projects

Paths and walkways are where the fines and screenings do their work. Limestone screenings, also called 3/8 inch minus screenings, are the fine material that beds a flagstone or paver path and fills the joints between them.

Screenings also make a tight top dressing over a compacted roadstone base. They knit together and give you a surface that stays walkable instead of rolling underfoot.

For a garden path that wants a softer look, walkway gravel is a finer, walkable surface than drive rock. 3/8" Natural Pea Gravel works for walkways, play areas and patio bedding, and it is what Iowa yards call Natural Pea Gravel.

Underneath any of those, Class A Roadstone is the compacted base. It is 3/4 inch crushed limestone with the fines left in, and it carries a drive, a parking pad or a shed base.

Where a new drive or a lane that runs heavy equipment needs a coarser start, 1 Inch Roadstone goes down first as the lower course. Driveway Gravel tops an existing drive or lane that has thinned out.

For water, Clean Rock is washed and open graded, so water moves straight through it. It backfills subdrains, drainage tile, pipe bedding and retaining walls.
