Asphalt Paving in Biloxi, MS

Asphalt paving in Biloxi is mostly a fight with water. The city sits at about 20 feet of elevation between the Mississippi Sound and Back Bay, it averages 66.8 inches of rain a year over roughly 110 wet days, and the City of Biloxi notes that nearly half of Biloxi is in a FEMA flood zone. Asphalt itself handles that weather fine. What fails is the ground under it. A driveway or lot laid on a thin, wet base sags, ruts and breaks into potholes, often within a few seasons. One built on a well-drained, compacted stone base, with water sent somewhere on purpose, can last for decades.

Why coastal pavement fails from the bottom up

When the base under asphalt stays saturated, it loses its ability to carry weight. Every car that crosses it pushes the stone down a little and flexes the asphalt above. Fine cracks show up first, then the web pattern people call alligator cracking, then a pothole. Low spots that hold water after a summer storm speed all of this up, because standing water works its way into every crack.

We treat the base as the main event. On a new driveway or lot, we strip out soft or organic material, add and compact crushed stone, and shape the grade before any hot mix arrives. HomeGuide describes a typical residential section as 2 to 3 inches of compacted asphalt over 6 to 8 inches of compacted gravel base, and 3 to 4 inches over 8 to 10 inches where heavier vehicles park. Our quote says which section we are building and where.

Getting the water off and away

A flat lot is harder to drain than a sloped one. On much of the coast the ground is nearly level, so a driveway has to be shaped deliberately: a crown or cross slope to shed rain, a finished height that keeps water from running toward the garage, and an edge that sits on compacted soil instead of hanging over a soft shoulder. Where a driveway crosses a roadside ditch, the pipe under it has to be the right size and set at the right grade, or it backs water up the ditch. The city's own floodplain guidance warns that a plugged channel can cause backwater flooding upstream.

Heat, rain and the paving calendar

Winters are mild here, and snow averages a tenth of an inch a year, so paving can run nearly all year. The real limits are rain and heat. Hot mix should not go down on wet stone, and summer afternoon storms can close a work window fast, so we schedule around the forecast. July and August average highs near 90 degrees, and the record is 104. Fresh asphalt stays soft in that heat. HomeGuide suggests keeping cars off a new driveway for 24 to 48 hours in normal weather and 3 to 5 days in hot weather, and heavy vehicles off for at least a week.

Permits, flood zones and the street

Who needs to sign off depends on what the job touches. The City of Biloxi requires an Engineering excavation permit to dig or cut into a public street, and its Flood Damage Prevention Ordinance controls filling and grading that could add to flooding. The city's residential permit checklist asks for a site plan that shows the driveway, and tells owners to check the maps for flood zones, historic districts and easements. A driveway that connects to a state route such as US 90, MS 15 or MS 67 needs an MDOT permit on form MND-001, and any pipe under that driveway has to meet MDOT's culvert criteria. We work out which rules apply to your address before we schedule anything.

After a storm

Tropical storms and hurricanes are part of life here. The worst storm surges on record at Biloxi came in 1855, 1906, 1909, 1947, 1969 and 2005, when Katrina pushed a 30-foot surge ashore. Even an ordinary tropical storm can leave pavement sitting under water for a day or more. Once it drains, look for new soft spots, edges that have washed out, sunken areas over utility trenches, and sand or debris packed into cracks. A quick repair before the next heavy rain stops a small washout from turning into a rebuilt section.

What a new driveway includes

• Measuring, checking grade and noting the road and ditch connection
• Removing old asphalt, concrete, shell or worn gravel
• Digging out soft ground and replacing it with compacted stone
• Building and compacting the base to the depth in your quote
• Placing and rolling hot-mix asphalt to the stated compacted thickness
• Finishing edges, the garage joint and the street apron
• A first-season care sheet and a sealcoating timeline

We work out of Biloxi and cover the coast on both sides of it. West along US 90 are Gulfport and Long Beach, then Pass Christian, with Diamondhead up I-10 near the Bay of St. Louis. North across Back Bay, D'Iberville sits where I-110 meets I-10, with steady commercial growth along the interstate. East over the Biloxi Bay Bridge are Ocean Springs and then Gautier in Jackson County. Each area is a little different: older beachfront neighborhoods with raised homes and shaded lots near the water, newer subdivisions on slightly higher ground to the north, and plenty of commercial lots along the highways. Town pages below cover what is specific to each place, from local permit offices to flood-zone and drainage conditions.
