Materials delivered in Washington 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.
CA-6 is the base material for this ground. It is dense graded crushed limestone, and the fines stay in the mix so it knuckles down into a tight surface for drives, pads and backfill.
Ground conditions across Washington County
Across the Southern till plain and claypan country, a tight claypan sits close to the surface and stops water moving down.
Rain perches on top of that layer and the ground stays saturated for weeks. Unbound base pumps under traffic when the subgrade is that soft.
Sheet and gully erosion cuts in where thin loess is bared, and bank scour follows high water. Riprap armors those edges.
The working season runs longer than upstate at both ends, but a wet winter and spring keep sites soft well into April. Late summer and fall are the reliable windows for a delivery.
Choosing the right material
Clinton County sits on the same Southern till plain and claypan country ground as Washington County. The base and drainage choices carry over unchanged.
St. Clair County and Randolph County sit on different ground, with deep loess over older Illinoian drift and thick silty alluvium along the Mississippi.
Water moves through that ground instead of perching on it.
On claypan, a clean washed stone like CA-7 or CA-11 carries water away where a fines-bearing material would hold it. On the loess uplands, drainage matters less and slope armoring matters more.
Let the ground decide.
