Start with CA-6, also called road base or 3/4 dense grade. It is the Illinois base material: dense graded crushed limestone with the fines left in.
It goes under driveways, parking pads, shed and garage bases and trench backfill.
Materials Delivered in Henry County
Article 1004.01 sets the coarse aggregate gradations CA 1 through CA 20, and Article 1005.01 sets the riprap gradations RR 3 through RR 7.
Those numbers are how material is specified and ordered in this state.
CA-6 is dense graded crushed limestone with the fines left in. It is the base material for driveways, parking pads, shed and garage bases and trench backfill.
If you need a secondary name, crusher run means the same thing.
CA-7, also called #57 stone or 1 inch clean stone, is washed clean stone with no fines. It beds pipe, drainage trenches, French drains and concrete flatwork.
CA-11 is the 3/4 inch clean washed stone sold alongside CA-7 for bedding, drainage and concrete work. CA-16 chips are 3/8 inch chips for permeable paver bedding, drainage around tanks and topping a compacted base.
Lime screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe.
Mason sand is the fine clean sand for brick and block mortar, paver joints, sandboxes and volleyball courts. Natural Pea Gravel and river gravel are rounded stone for walkways, play areas and dry creek beds, and large river rock covers heavier decorative work.
Fill dirt raises grade before a CA-6 base course goes down.
Ground Conditions Across Henry County
The working season runs from the spring thaw into late fall and is a little shorter than downstate. Frozen ground stops compaction in the winter, so timing a delivery matters more here than it does farther south.
Across the Northern Illinois till plains and Rock River country, the ground runs from tight till and a high water table on the flat ground to sand plains that drain almost too fast. Snowmelt and spring rain on frozen ground push water across the surface.
Where the ground stays wet, a clean washed stone such as CA-7 or CA-11 gives water somewhere to go before a base goes down. Where the ground drains fast, a fines-bearing material like CA-6 holds together better as a compacted base.
Gully and sheet erosion shows up on steeper till slopes across this part of the state, and wind moves bare sand. Riprap armors banks, culvert outlets and pond edges.
Winters here bring repeated freeze and thaw and heavy frost action in unbound base and shallow footings. Frost depth is about 42 inches across the northern counties, and the local building department sets it.

A dump truck tips the load in one pile on site. Plan where that pile lands before the truck arrives, because the material stays where it is tipped.
Choosing the Right Material
Henry County sits in the Northern Illinois till plains and Rock River country, where Wisconsin Episode till and loamy prairie soils lie over dolomite. The sand and gravel of the Green River Lowland breaks that ground up.
Stark County lies in the Grand Prairie till plain of central and eastern Illinois, flat to gently rolling till under deep, dark prairie silt loams. That is finer and more uniform ground than Henry County's mix of till and sand plain.
Knox County and Rock Island County both sit in the Western Illinois loess uplands, where deep loess covers older Illinoian drift on rolling uplands. That loess is silty and settles differently under a base than the till and sand here.
On ground that drains slowly, lead with clean washed stone for drainage and a fines-bearing base above it. On sand plain that drains fast, CA-6 as a compacted base does more of the work.
