Asphalt work for Cobalt properties

A mine gave this village its name. The Madison Cobalt Mine was discovered in 1847 in the Mine La Motte and Fredericktown mining district, and the village sits in the northeast corner of Madison County with Fredericktown, the county seat, directly north of it.

Paving here means driveways, church and shop lots, and lanes that carry pickups and equipment. We compact rock in layers and lay hot-mix asphalt over it, with grades that push water off the surface rather than letting it soak in. On a longer drive, recycled asphalt millings and chip seal are worth pricing against hot mix. Call (866) 490-7680 for a free estimate and 25% off.

Driveway paving in Cobalt

Ozark hill drives run steep in places and flat in others, and the steep sections are where water does the damage. We cut out soft ground, compact rock in lifts and pave, typically 2 to 3 inches of compacted hot mix for a home drive. On a grade we shape the cross slope and firm up the shoulders so runoff leaves the surface instead of running its whole length.

Parking lot paving in Cobalt

Lots around here belong to churches, shops and small businesses, with the occasional equipment yard. A loaded trailer puts its weight on a small footprint, so base depth is set by the heaviest thing that parks there. We slope the surface toward a planned outlet and keep runoff from heading straight at a building's foundation.

Parking lot paving

Road construction & private roads

Private roads, shop access lanes and farm drives need a crown, a clear ditch and compacted rock before any surface goes down. We build that first, then pick hot mix where trucks run and chip seal or millings where traffic is light. Edges get support where a lane runs along a hillside.

General asphalt paving & repair

A lot of rural pavement near Cobalt fails at the edges, where water gets under the asphalt and tires break the shoulder down. Overlays, edge rebuilds and better drainage are often the fix. When the base is gone, we rebuild it before we pave.

What's under a Cobalt driveway

This is St. Francois Mountains country, with granite and rhyolite knobs and hill ground that puts rock near the surface in one spot and clay a short distance away. Clay holds water and moves with it. Freeze-thaw winters lift anything wet under pavement. Drainage and compaction come before thickness.

Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.

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

Cobalt paving questions

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

Is paving worth it on a drive used mostly by trucks?

Usually, if the base is built for them. Truck weight is carried by compacted rock more than by asphalt thickness, so a thin surface over shallow rock ruts quickly. We size the base for the heaviest vehicle first, then set the hot mix depth to match it.

What is the difference between chip seal and hot mix?

Chip seal is liquid asphalt with stone chips rolled into it over a prepared base, and it costs less per foot. Hot mix is asphalt and aggregate combined hot, then laid and compacted in lifts, and it handles heavy turning and parking better. Traffic decides which fits.

What goes into the price of paving in Cobalt?

On a Cobalt job the price comes down to size, how much base work is needed, the asphalt thickness, whether old pavement has to come out, drainage fixes and how easily trucks can reach the work. Your written estimate lists each of those so you can compare it with other bids line by line.

Can you pave where a truck cannot easily turn around?

Usually yes, and it is a common question on Cobalt lanes. We plan the approach before the day of paving, and building a turnaround into the job often costs less than you would expect while making the drive far more usable.
