Built for Huntleigh's ground
West county sits on rolling loess upland, and the county soil survey lists low strength and frost action as limits for local roads, solved with adequate base material plus ditches and culverts. Shade from old trees keeps pavement damp longer, so freeze-thaw works harder on it. Grading comes before anything else.
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 Huntleigh estimate is sized to the soil, the traffic and the drainage on your property.
