Asphalt Paving in Laredo, TX

Asphalt paving in Laredo has to handle two things most cities never test at the same time: extreme heat and heavy freight. Laredo has a hot semi-arid climate with a record high of 115 degrees, and it averages about 74 afternoons a year at 100 degrees or above. It also sits at the southern end of I-35 and is the largest inland port in the United States, with four international road bridges and two rail bridges. When a loaded truck sits on asphalt that has been baking all afternoon, the asphalt moves. Pavement here has to be designed for that, from the base up. Asphalt contractors who mostly pave light residential drives may not size a truck lot the same way, so ask what thickness they plan for loaded trailers.

Rutting and shoving

Hot asphalt softens. Under steady heavy wheels, a thin or poorly compacted surface ruts in the wheel paths and shoves into ridges where trucks brake and turn. The fix is structural: enough compacted base, enough asphalt thickness and good compaction. HomeGuide lists 2 to 3 inches of asphalt over 6 to 8 inches of base for a car driveway, 3 to 4 inches over 8 to 10 inches for heavier vehicles, and 4 inches or more for commercial lots. In Laredo truck lanes, we treat those as minimums, and we design heavy sections where the trucks actually go.

Caliche and dry ground

Caliche, a lime-cemented soil, is common in South Texas and widely used as base. It is firm and cheap when dry, but it loses strength when it gets wet. Laredo only sees about 20 inches of rain a year, but storms tend to come in bursts, and water that gets under the edges of a lot or driveway softens the caliche right where traffic is heaviest. We check the base on every job, rebuild the soft spots, and grade the surface so water leaves fast.

Paving in the heat

In Laredo, getting the mix down hot is easy; the challenge is that the finished mat stays soft long after the rollers leave. HomeGuide's advice for hot weather is to wait 3 to 5 days before parking on new asphalt. So our summer crews start at first light, keep trucks off fresh sections longer, and give you a specific day for each area to reopen.

Sun damage

UV light and heat dry out the asphalt binder, turning a black surface gray and brittle, and starting the cracking that lets water in. A sealcoat every few years, plus filling cracks as they appear, slows that down. In Laredo's sun, sealed pavement lasts noticeably longer than pavement left bare.

Permits for driveways and curb cuts

In Laredo, the City's Building Development Services office on Houston Street handles permits. New driveways and new curb cuts generally need a permit, and widening an existing driveway usually does too; replacing a driveway in the same footprint without changing the curb cut is generally treated differently. Rules change, so we confirm the current requirements with the city for your address before scheduling. Access onto a state highway such as US 59 or US 83 goes through TxDOT's driveway permit.

What goes into a typical driveway

• Measuring, checking slope and looking at the curb cut
• Removing old asphalt, concrete or loose caliche
• Rebuilding soft base and compacting it in layers
• Grading so water drains to the street
• Placing and rolling hot-mix asphalt to the quoted thickness
• Finishing edges at the garage, sidewalk and curb
• Instructions for the first weeks and a date for the first sealcoat

Laredo is where most of our work is, from north Laredo subdivisions to central neighborhoods and the industrial areas along I-35 and the Loop. We also travel to the towns and communities around it: Rio Bravo and El Cenizo down US 83, Zapata and San Ygnacio farther south, the colonias and rural subdivisions north and east of town such as Botines, Ranchos Penitas West, Tanquecitos South Acres and Pueblo Nuevo, the oil-field towns of Mirando City, Oilton and Bruni along SH 359, and Hebbronville, Encinal, Cotulla and Freer. Distances out here are long, so we schedule outlying jobs together. Rural properties outside city limits deal with the county or TxDOT for work at the road; each town page covers the details. When you compare paving companies for a ranch drive near Hebbronville or Freer, ask how travel and scheduling are handled for a job that far out.
