Why the base matters in Park Hills
The county soil survey maps clayey soils over dolomite and loamy soils over sandstone across the Farmington Plain, and it notes low strength for vehicle traffic that suitable base material corrects. Add freeze-thaw winters and you have the reason we spend real time on rock and drainage before any asphalt is placed.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
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 Park Hills estimate is sized to the soil, the traffic and the drainage on your property.
