Asphalt Paving in Baytown, TX

Asphalt paving in Baytown has to cope with more water than most of the country sees. The city averages about 64.7 inches of rain a year over roughly 111 wet days, June alone averages more than 7 inches, and the whole town sits around 23 feet above sea level with Galveston Bay on two sides and Cedar Bayou on the third. Snow is a non-issue. Water, heat and soft ground are the issues. A driveway or lot that sheds water and sits on a firm base can last decades here. One that holds puddles over wet clay starts to rut and pothole within a few seasons.

What sits under a Baytown driveway

Baytown grew on reclaimed marsh, swamp and coastal prairie, and the ground below it is layered sand and clay. Much of the prairie from the Colorado River to the Trinity is mapped as Lake Charles clay and similar soils: dense, slow-draining clays that crack an inch or more wide in a drought and swell when they soak up water. That movement pushes up on a slab or a thin base and then lets it settle again. For asphalt, the answer is a thick enough layer of compacted crushed stone or recycled base to spread the load, and grading that keeps rainwater moving away from the pavement instead of soaking into its edges.

Subsidence and flood history

Baytown knows better than most places what happens when the ground drops. Groundwater pumping in the 1960s through the 1980s lowered parts of the area by many feet; the Brownwood subdivision sank roughly 10 to 15 feet and was abandoned after Hurricane Alicia in 1983, and the land is now the Baytown Nature Center. The city has since moved largely to surface water. For paving, the lesson is simple: low spots collect water, and water ruins asphalt. On every estimate we shoot the grades, look at where the street, ditch or storm inlet sits, and set the slope so the new surface drains.

Heat and timing

Summer highs near 90 degrees and a record of 109 mean asphalt here spends months soft and in strong sun. That works in our favor during paving, since the mix stays workable longer, but it also means new asphalt marks easily for the first weeks and that sun oxidizes an unsealed surface quickly. We plan paving to avoid rain on fresh base, ask you to keep heavy loads off new asphalt while it firms up, and schedule the first sealcoat a few months later once it has cured.

Who controls the edge of your driveway

Where a driveway meets the road, the rules depend on where you live. Inside Baytown city limits, the city handles the street side. In unincorporated Harris County, around Highlands, Channelview, Crosby and Barrett, the county requires a permit to build, widen, replace or repair a driveway or culvert in the right-of-way, which runs from your front property line to the centerline of the road, and asks that culvert locations be staked in the ditch when you apply. A driveway that opens onto a state highway such as SH 146 needs a TxDOT access permit. We tell you at the estimate which of these applies and confirm current requirements before any work reaches the road.

What a driveway job usually includes

• Measuring the area and checking grades, the ditch or curb and any culvert
• Removing old asphalt, concrete or shell and hauling it off
• Digging out soft or pumping subgrade and replacing it with compacted stone
• Grading and compacting the base so water runs off
• Placing and rolling hot-mix asphalt to the thickness in the quote
• Finishing edges and tapering to the garage slab and street
• Telling you when it can be driven on and when it should be sealed

Baytown is home base. We also work in La Porte, Deer Park and Pasadena across the ship channel, in Highlands, Channelview, Crosby, Barrett, Sheldon and Huffman in unincorporated east Harris County, and in Mont Belvieu, Beach City, Cove, Old River-Winfree and Anahuac in Chambers County, plus Dayton and Liberty up SH 146. Each area has its own mix of ground and rules: bay-front towns fight storm surge and low elevations, the county areas north of I-10 deal with ditches, culverts and county permits, and towns like Mont Belvieu are growing fast on new subdivisions. Each town page covers what is different there.
