What's under a Pittsfield driveway
This is not flat central Illinois ground. Slopes send water fast, hollows hold it, and Bay Creek takes runoff north and east of the city. Both conditions fail a surface built on a soft base. We compact in layers, grade every job to a real outlet and support the edges against winter freeze-thaw.
Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.
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 Pittsfield estimate is sized to the soil, the traffic and the drainage on your property.
