Asphalt Paving in College Station, TX

We pave and repair asphalt in College Station, Texas, including parking lots, private drives, long acreage approaches, and residential driveways where the run is long enough that asphalt makes financial sense. Work covers new paving, overlays, pothole and section patching, crack filling, sealcoating, and striping. Asphalt lives or dies on two things in this climate, the base under it and how quickly water gets off it, and both are decided before the first load is placed.


When Asphalt Is the Right Call and When It Is Not

Asphalt wins on area. The more square footage being covered, the more the lower install cost per foot matters, which is why it makes sense for apartment and multifamily parking, church and school lots, and the long approaches out toward Wellborn and Millican. Concrete wins on concentrated weight and on heat, since a parked trailer jack or a dumpster leg will press into asphalt on a July afternoon. On a standard in town residential driveway, concrete is usually the better long term answer, and we will tell you that rather than sell you the pour we would rather do.

What Asphalt Work Is Done in College Station, TX?

Asphalt work here falls into four buckets. New paving, which means building the base and laying hot mix on ground that has never been paved. Overlays, where a new layer goes over an existing surface that is still structurally sound. Repairs, covering pothole patching, full depth patching where the base has failed, crack filling, and edge repair. Maintenance, meaning sealcoating and restriping. Commercial property owners usually need a mix of all four across a single lot, since parking areas wear unevenly and the drive lanes fail long before the parking stalls do.

What Goes Into a New Asphalt Installation in College Station?

New asphalt is built in layers and the top one is the least important. The area is cleared and excavated, then the subgrade is compacted, which in College Station clay is the step that everything else rests on. A crushed stone base goes in and gets compacted to a specified depth. The asphalt is placed hot and rolled while it is still hot, since compaction is what locks the aggregate together and there is a narrow window to get it. Grade is set as it goes, so water runs off the surface to a specific place rather than pooling. Edges get compacted deliberately, because an unsupported edge is where an asphalt lot starts falling apart.

Why Does Asphalt Fail Early in College Station, TX?

Sun and water, in that order. Ultraviolet exposure breaks down the binder holding the aggregate together, which is why asphalt goes from black to gray and then starts to look dry and rough. Once the surface is porous, water gets in, and once water reaches the base, the structure underneath starts to move. Clay makes that worse, since saturated clay loses strength and the pavement above it flexes under traffic until it cracks. Heat plays its own part, because pavement that softens on a hundred degree afternoon will deform under a concentrated load that would not bother it in March. Nearly every failure traces back to water reaching the base.

Asphalt Questions College Station, TX Property Owners Ask

  • What time of year is best for asphalt paving in College Station?

    New asphalt in Bryan can usually take light vehicle traffic within a day or two, once the surface has cooled and set. Asphalt keeps hardening for several months, and in Central Texas summer heat a fresh surface stays soft longer than it would in cooler weather. During that period, parking in one spot for long stretches, turning wheels while stopped, or setting down heavy trailer jacks can leave permanent depressions.

  • How soon can you drive on new asphalt?

    Asphalt can go over an existing gravel drive in Bryan when the gravel is regraded, compacted, and deep enough to work as a base, which usually means adding material and reworking it first. Paving over old asphalt is called an overlay, and it works only where the surface underneath is still structurally solid, since cracks and low spots reflect up through the new layer within a season or two. Neither approach corrects a failed base. If water stands on the existing surface after a rain, the ground below it has to be fixed before anything new goes on top.

  • Why are the edges of my asphalt crumbling?

    Potholes form in Bryan asphalt when water gets down into the aggregate base and weakens it. Sun dries out the binder and opens small cracks, Central Texas thunderstorms drive water through those cracks, and the saturated base loses the strength that was holding the surface up. Traffic then presses the weakened area down until it breaks apart. Expansive clay across Brazos County speeds the process up, since the soil under the base is already swelling and shrinking on its own. That is why patching a pothole without correcting the drainage tends to produce the same hole in the same spot.

  • Can asphalt be laid over an existing concrete surface?

    An asphalt driveway in Bryan typically lasts 15 to 20 years with sealcoating every two to three years and crack filling as needed. Central Texas sun sets that range, since ultraviolet light strips the binder out of the surface and leaves it brittle. A driveway built on a properly compacted base and sealed on schedule reaches the top of that range. One laid over soft ground or left unsealed can need resurfacing in under ten years, and the failure usually starts at the edges where there is nothing holding the asphalt in.

  • Do potholes keep coming back after they are patched?

    They do when the patch was a surface fix and the real problem is underneath. A pothole forms because water got into the base and the material there lost strength, so filling the hole without rebuilding the base leaves the cause in place. Full depth patching removes the failed material and rebuilds it, which is why it holds when a surface patch will not.

How Often Should Asphalt Be Sealcoated in College Station?

Sealcoating is UV protection more than anything else, and in Central Texas sun that clock runs faster than it does in most of the country. Every two to three years is the usual range for a lot that sees regular traffic, with newly placed asphalt waiting several months before the first coat so it can cure. The right timing depends on how exposed the lot is and how much traffic it takes, so a shaded lot behind a building will go longer than an open one facing south. Sealcoating is not a structural repair and it will not hold a failing lot together, but on sound pavement it is the cheapest way to extend the life of the surface. Cracks get filled before sealcoat goes down, never after.

What Kind of Asphalt Repairs Are Possible?

There are three levels and the right one depends on how deep the problem goes. Crack filling seals openings before water gets down to the base, and it is the cheapest thing on this list by a wide margin. A surface patch fills a pothole or a worn area where the base is still intact, which buys time but does not fix anything below. Full depth patching cuts out the failed section down through the base, rebuilds it, and repaves, which is the only real fix when the ground underneath has gone soft. A lot that has been surface patched in the same spot twice is telling you it needed full depth work the first time.
