Why the base matters in Kampsville
The village sits on the west bank of the Illinois River, and river ground holds moisture longer than upland does. Moisture in a base freezes in winter, lifts the asphalt and leaves a crack behind. We remove material that will not compact, build rock in layers and set a grade that moves water off before the freeze arrives.
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 Kampsville estimate is sized to the soil, the traffic and the drainage on your property.
