What's under a Trenton driveway
Clinton County farm ground is close to level, and level ground is slow to drain. Clay-heavy soils common around St. Louis hold water near the surface in wet seasons, and freeze-thaw winters lift any pavement built over that. We remove soft soil, compact rock in lifts and set grades that shed water instead of trapping it.
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 Trenton estimate is sized to the soil, the traffic and the drainage on your property.
