Ground, water and winter in Wellston
Loess over clay is the rule across this part of the county, and the county soil survey calls for adequate base material plus ditches and culverts on local roads because of low strength and frost action. Winters here freeze and thaw repeatedly. We build base for that and grade so water is gone before it can freeze underneath.
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 Wellston estimate is sized to the soil, the traffic and the drainage on your property.
