What's under a Donnellson driveway
The village drains south toward Yankee Creek, part of the Shoal Creek and Kaskaskia River watershed. Slow-draining soils are common in this part of Illinois, and winter freeze-thaw punishes a weak base. We build up firm compacted rock, keep edges supported and set grades so water leaves the pavement instead of soaking in.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
Compacted asphaltTypically 2 to 3 in. for a car drive
Stone baseTypically 4 to 8 in., compacted
Drive on itUsually 2 to 3 days, longer in heat
First sealcoatTypically 6 to 12 months after paving
Typical ranges. Your Donnellson estimate is sized to the soil, the traffic and the drainage on your property.
