Hot-mix asphalt, laid right in Dupo

Settlers laid out Prairie du Pont here around 1750, reportedly choosing the spot because it sits 10 to 12 feet higher than Cahokia and gave better protection from Mississippi floods. That instinct still applies. On American Bottom floodplain ground, the elevation and drainage of a driveway or parking lot matter more than the thickness of the asphalt.

The village grew up around the railroad switching yards, now the Union Pacific Dupo Yard, and I-255 exit 9 brings traffic in at South Main Street. We pave home drives, business lots, truck and equipment pads and private roads. Base compacted in layers, grade set so water leaves, hot-mix asphalt rolled tight.

Driveway paving in Dupo

Floodplain ground under a driveway can be firm in August and soft in March, so we build for the wet season. Soft subgrade comes out, clean rock goes in and gets compacted in layers, and the surface is graded so runoff leaves at the edges. Home drives typically get 2 to 3 inches of compacted hot-mix, more where a work truck or trailer sits.

Parking lot paving in Dupo

Lots near Main Street and the I-255 ramps, and yards serving the rail traffic, take heavy slow trucks. That combination needs a deeper base and entrances built for constant turning. We grade to planned drains, because standing water on flat bottomland pavement does not go anywhere on its own. Work can be staged to keep half a lot open.

Parking lot paving

Road construction & private roads

Access roads to yards and industrial buildings, plus private drives shared by several homes, carry loaded trucks at low speed. We build the base deeper where they stop and turn, crown the surface for runoff, and tie the entrance cleanly into Route 3 or the local street so the joint holds up under the weight.

General asphalt paving & repair

General paving in Dupo can be as simple as a new apron where the drive meets the street or as big as an overlay across a business lot. Either way the estimate spells out the base work, the asphalt thickness and what the finished surface should look like.

Why the base matters in Dupo

This is American Bottom floodplain, deep river-laid clay, silt and sand behind a levee and drainage canal system. That ground holds water, and water under pavement lifts it every freeze-thaw winter. We check where runoff can actually go before planning anything, then dig out soft material and compact clean rock in layers.

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 Dupo estimate is sized to the soil, the traffic and the drainage on your property.

Dupo paving questions

Straight answers for Dupo homeowners and property managers. Anything else, call (866) 490-7680.

Does bottomland ground rule out asphalt?

No. It changes how the base is built. On floodplain ground we go deeper on rock, pay closer attention to where water exits, and sometimes raise the finished grade a little. Asphalt flexes with seasonal movement, which is an advantage on ground that shifts.

Can you pave a yard that semis use daily?

Yes, and it gets built differently than a car lot. Loaded trucks that stop and turn push the base harder than highway speed does, so the rock goes deeper and the asphalt thicker at those points. We ask about traffic patterns before sizing anything.

Should I sealcoat my new driveway right away?

No. Fresh asphalt in Dupo needs time to cure before it is sealed, typically several months and often up to a year. Sealing too early can trap oils in the pavement. After that, sealing every few years helps it resist water, sun and salt.

What about the apron where my drive meets the street?

In Dupo that is the piece that takes the most abuse, so it gets extra attention: a firm base, a tie-in that sits flush with the road, and a shape that moves water to the ditch or gutter instead of back toward the drive.
