What's under a Okawville driveway
Plum Creek runs through the village and the Kaskaskia River lies two to three miles north, so parts of this ground sit low and drain slowly. Water under pavement is what breaks it, especially with freeze-thaw winters. We remove soft soil, compact the rock base in lifts, and grade so runoff leaves the surface.
When you compare bids, ask each contractor for three numbers in writing: the compacted asphalt thickness, the base depth, and what happens to the water. Those three decide how long the surface lasts.
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 Okawville estimate is sized to the soil, the traffic and the drainage on your property.
