Why the base matters in Parkway
Franklin County sits on the northern edge of the Ozarks, with cherty red clay over dolomite common through the Salem Plateau and karst features like sinkholes and springs across the county. Clay holds water, freeze-thaw winters drive it into cracks, and pavement fails from below. Drainage and a compacted base come first.
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 Parkway estimate is sized to the soil, the traffic and the drainage on your property.
