What's under a Leadington driveway
About half of St. Francois County is the gently rolling Farmington Plain, where NRCS maps clayey soils over dolomite and loamy soils over sandstone, and notes low strength for vehicle traffic on several soils, correctable with suitable base material. Freeze-thaw winters push water into anything that opens, so we drain first.
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 Leadington estimate is sized to the soil, the traffic and the drainage on your property.
