Ground, water and winter in Elsah
Jersey County upland soils formed in windblown loess over limestone and shale, and near the western bluffs that loess runs deep. Silt moves when water runs fast across it, and undermined edges are how pavement fails on sloped ground. We compact rock in lifts, control where runoff crosses and leaves, and shape shoulders so nothing washes out beneath the asphalt.
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 Elsah estimate is sized to the soil, the traffic and the drainage on your property.
