What's under a Josephville driveway
The county soil survey notes upland soils that lack strength for traffic without added crushed rock in the road base, plus clayey subsoils that shrink and swell. Add freeze-thaw winters and water becomes the real enemy. We grade so runoff leaves the pavement, replace soft soil, and compact rock in layers before any hot mix goes down.
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 Josephville estimate is sized to the soil, the traffic and the drainage on your property.
