Why the base matters in Herculaneum
Limestone bluffs, a creek mouth and river bottom in one small city means drainage varies block to block. Ridges near the Mississippi carry thick loess, while slopes hold cherty red clay over limestone. Both trap water in ways freeze-thaw winters exploit. We remove soft soil, compact rock in layers and grade for runoff.
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 Herculaneum estimate is sized to the soil, the traffic and the drainage on your property.
