Built for Sparta's ground
Randolph County uplands run to silt and clay that hold water, and this region's winters cycle above and below freezing all season. Water in a base plus that cycle is what cracks and heaves pavement. We build the grade to shed runoff, compact rock in layers and support edges so the surface does not unravel.
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 Sparta estimate is sized to the soil, the traffic and the drainage on your property.
