Class A roadstone is the base most drives, lanes and pads here start from. It is crushed limestone with the fines left in, so it binds and compacts.

County engineers and city entrance standards write it as Class A roadstone.

Class A roadstone is the standard Iowa base course. It goes under driveways, parking pads, shed bases and farm lanes.

10.

For a new drive, a soft spot or a lane that carries heavy equipment, use 1 Inch Roadstone. It is the coarser grade, laid under a finer surface course.

To top an existing drive that has thinned out, order Driveway Gravel.

For drainage work, 3/4" Crushed Stone is a loose, free draining stone for drive surfacing, pipe bedding and trench backfill. #57 Stone covers drainage runs, subdrain backfill and concrete aggregate, and Iowa concrete stone gradations are written D57 and D67.

Sand and soil round out the list. Mason Sand goes into brick and block mortar, paver joints and horse arena footing.

Garden Soil is blended richer than plain black dirt for raised beds and vegetable gardens, and Shredded Mulch holds moisture through a dry August.

Ground Conditions Across Worth County

Worth County spans more than one ground region, and the two halves behave differently. In the Des Moines Lobe, around Northwood, Manly, Fertile and Joice, the ground is thick, compact pebbly loam till of the Dows Formation, 45 to 60 feet deep.

Kettles and closed depressions hold water, and most of the ground only drains at all because it is tiled. Snowmelt and spring rain sit on the surface where the ground below is still frozen.

In the Iowan Surface, around Kensett and Grafton, loamy glacial till was planed down by cold-climate erosion, with a thin and patchy loess cover. A residual stone line or pebble band sits near the surface, and unusually large granite and quartzite erratics are scattered through the fields.

Limestone bedrock is shallow along the eastern edge.

Drainage networks there are well established, but stream gradients are low, so water moves slowly and pockets of old wetland ground still hold water. Limestone aquifers keep the rivers running in dry spells and can put groundwater close to the surface.

Clean rock and washed stone keep that water moving.

Erosion follows the same split. In the Des Moines Lobe, ditch and tile outlet scour and washouts where runoff concentrates on the moraine ridges.

Compaction waits for the frost to come out and for the flat ground to shed its spring water. Base and paver work runs from late spring to the fall freeze, and a wet spring shortens that window.

Long, cold winters bring a deep frozen season and repeated freeze-thaw that heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches; the local building official sets footing depth, and northern jurisdictions may ask for more.

Choosing the Right Material

Mitchell County sits on the Iowan Surface, the same ground region as Kensett and Grafton. Loamy glacial till planed down by cold-climate erosion, a thin and patchy loess cover, and a residual stone line near the surface.

The ground is the same, so the base and drainage choices are the same.

Winnebago County and Cerro Gordo County both sit on the Des Moines Lobe, the same ground region as Northwood, Manly, Fertile and Joice. Thick, compact pebbly loam till of the Dows Formation, 45 to 60 feet deep, with sand and gravel along old meltwater channels.

The ground is the same as the lobe side of Worth County.

Where the ground is the same, the material choice is the same. A compacted roadstone base under drives and pads, and clean, open graded stone where water needs to move.
