Ground, water and winter in Smithboro
Clay-heavy soil across this part of Illinois drains slowly, and water that cannot leave a surface freezes under it and lifts the asphalt. Drainage does more for pavement life than thickness ever will. We remove soft material, compact base rock in lifts, crown the surface, and set grades so runoff has a clear path off.
When you compare bids, ask each contractor for three numbers in writing: the compacted asphalt thickness, the base depth, and what happens to the water. Those three decide how long the surface lasts.
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 Smithboro estimate is sized to the soil, the traffic and the drainage on your property.
