What's under a Smithton driveway
The village sits on relatively level, slightly higher ground in southern St. Clair County, and upland ground here is capped with deep windblown loess silt. Level and silty means water has to be given a path off. We proof the subgrade, replace soft material, compact base rock in layers, and build the slope in.
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 Smithton estimate is sized to the soil, the traffic and the drainage on your property.
