What's under a Bonne Terre driveway
Rolling Ozark hills with red clay over limestone drain unevenly: fast down the slopes, slow in the flats. Freeze-thaw winters then lift anything above trapped water. Chat piles from the mining era still sit around the area. We plan drainage first, dig out soft clay, and compact clean rock in layers before asphalt.
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 Bonne Terre estimate is sized to the soil, the traffic and the drainage on your property.
