Why the base matters in Riverview
North county sits on loess upland over clay. The county soil survey flags low strength and frost action for local roads and recommends adequate base material with side ditches and culverts. Water that gets into a thin base and freezes is what lifts pavement and opens cracks, so drainage and rock depth come before asphalt.
The part of the job you can see is the last two inches. Ask what is underneath, how it will be compacted, and which way the finished surface drains.
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 Riverview estimate is sized to the soil, the traffic and the drainage on your property.
