Ground, water and winter in South Roxana
Ground on this side of Madison County runs from loess-capped upland down to river bottom, where deep river-laid clay, silt, sand and gravel sit behind the levee system. Either one holds water against pavement. We proof the subgrade, replace what will not compact, build the base in lifts, and grade so runoff has a planned exit.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
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 South Roxana estimate is sized to the soil, the traffic and the drainage on your property.
