What's under a Hermann driveway
Hermann sits in the Missouri River valley on the northern edge of the Ozark Plateau, where hillside soils are thin and upland soils carry chert. Slopes move water fast and can undercut a pavement edge. Freeze-thaw winters finish what standing water starts, so drainage goes into the grade before any asphalt.
The part of the job you can see is the last two inches. Ask what is underneath, how it will be compacted, and which way the finished surface drains.
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 Hermann estimate is sized to the soil, the traffic and the drainage on your property.
