Why the base matters in Prairie du Rocher
This village sits on the American Bottom below the bluffs, ground that holds water and drains slowly. In 1993 the creek levee was breached on purpose so backwater could get out, which tells you how flat it is. A wet base and a freeze move pavement, so grade and layered compaction come before any asphalt.
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 Prairie du Rocher estimate is sized to the soil, the traffic and the drainage on your property.
