Built for Grantwood Village's ground
Rolling upland here formed in loess, and the county soil survey calls out low strength and frost action for local roads, correctable with adequate base material and drainage. Clay-heavy soil holds water, and freeze-thaw winters lift anything built on a wet base. We grade for runoff and compact rock in lifts.
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 Grantwood Village estimate is sized to the soil, the traffic and the drainage on your property.
