Why the base matters in Pendleton
Warren County uplands formed mostly in loess and glacial till. The soil survey notes the deep loess near the river erodes in sheets and gullies, and that some upland flats stay wet. Wet, low-strength subgrade under a freeze-thaw winter is the standard recipe for cracked pavement, so rock and ditches come first.
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 Pendleton estimate is sized to the soil, the traffic and the drainage on your property.
