Ground, water and winter in Nason
Jefferson County uplands are loess-covered claypan, a dense subsoil that lets water through slowly, hard when dry and sticky when wet. Close to Rend Lake the ground is lower and wetter still. Freeze-thaw winters break pavement that sits on a wet base, so we drain the surface, remove soft material and compact the base in layers.
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 Nason estimate is sized to the soil, the traffic and the drainage on your property.
