CA-6, also called road base, is the dense graded crushed limestone most drives and pads in this county are built on. It is the base material for this part of the Grand Prairie till plain, where deep prairie silt loams sit over dense clay.
Ground Conditions Across Woodford County
Woodford County sits on the Grand Prairie till plain of central and eastern Illinois. The ground is flat to gently rolling Wisconsin Episode till under deep, dark prairie silt loams.
This is some of the flattest ground in the country, with dense clay subsoil beneath it and almost no natural fall. Water stands rather than runs after heavy rain, so a base that is under-built holds moisture and moves.
Erosion across the plain shows up as sheet erosion off bare silt loam and as gullying where field and yard runoff concentrates. Bare ground on a slope needs cover or armoring.
Base, driveway and paver work runs from the spring thaw into late fall. The ground is slow to dry in a wet spring and frozen solid through the winter.
Cold winters bring repeated freeze and thaw, and frost heave shows up in gravel drives, walks and shallow slabs each spring. Frost depth runs about 36 inches through most of central and eastern Illinois, rising toward the northern edge, and the local building department sets it.
Materials Delivered in Woodford County
Order by the job. A driveway, a patio, a drain and a raised bed each call for a different material.
CA-6 is the material to know first. It is dense graded crushed limestone with the fines left in.
Article 1004.01 sets the coarse aggregate gradations CA 1 through CA 20, so dense graded base is CA-6.
That is how base is specified and ordered in this state. It goes down under driveways, parking pads, shed and garage bases and trench backfill.
Clean stone is a separate family. CA-7 and CA-11 are washed, with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.
CA-16 chips are the 3/8 inch size for permeable paver bedding and drainage around tanks.
Lime screenings bed pavers and flagstone and backfill around pipe. Torpedo sand, the Illinois name for coarse washed sand, goes into concrete, leveling and bedding.
Choosing the Right Material
Woodford County sits on the Grand Prairie till plain of central and eastern Illinois, and Livingston County shares that same ground region. The soil, the flat grade and the drainage behave the same way across both, so the base and drainage choice does not change from one to the other.
Marshall County and Peoria County each span more than one zone. Both take in the Grand Prairie till plain and the Illinois River valley and its sand areas, so ground within those counties can differ from Woodford County ground and from itself.
Where the ground turns sandy, water moves through it instead of standing on clay. That changes how much clean drainage stone a trench or French drain needs.
On Woodford County's silt loam over clay, water stands. A base course of CA-6 with the fines left in sheds what it can, and clean CA-7 or CA-11 carries water away in a drain.
