Ground, water and winter in Chain of Rocks
Lincoln County ground runs from river bottoms to rolling loess and glacial till farmland, and the bottoms hold water. A wet base under asphalt moves, and freeze-thaw winters finish the job by lifting the surface. We cut the drainage, compact each layer, then pave so runoff leaves quickly.
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 Chain of Rocks estimate is sized to the soil, the traffic and the drainage on your property.
