Why the base matters in Leasburg
Ozark upland soils in this part of Crawford County developed from cherty dolomite, limestone and sandstone, and the common ridgetop soils have a fragipan over red cherty clay. Springs and caves are part of the carbonate bedrock here. A fragipan holds water above it, so drainage and a compacted rock base come first.
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 Leasburg estimate is sized to the soil, the traffic and the drainage on your property.
