What's under a Schram City driveway
Water here drains northwest through small tributaries toward the Middle Fork of Shoal Creek. Slow-draining soils are common in central Illinois, and winter freeze-thaw punishes a weak base. We dig to firm ground, compact the base in lifts, and grade so water leaves the pavement quickly.
A cheap bid usually gets cheap somewhere you cannot see. Ask what depth of stone goes down, how thick the asphalt is after rolling, and who fixes it if water still stands.
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 Schram City estimate is sized to the soil, the traffic and the drainage on your property.
