Asphalt Crack Sealing in Elizabeth, CO
Of everything that can be done to an asphalt driveway in Elizabeth, sealing the cracks each fall has the most effect on how long it lasts. Water is what destroys pavement here, and cracks are how it gets in. Elizabeth Asphalt Paving uses hot-applied rubberized crack sealant on driveways, private roads, and lots in Elizabeth, Gold Creek Meadows, and the neighborhoods along Running Creek.
Why Cracks Matter More at 6,500 Feet
A crack is an opening to the base. Once water gets below the asphalt, the Palmer Divide climate takes over: nights below freezing from November into March, warm afternoons in between, and dozens of freeze-thaw cycles each winter. Each freeze expands the water, widening the crack and loosening the aggregate base. By spring a hairline crack has become a quarter-inch gap, and after a few winters it becomes alligator cracking and potholes.
Sealing cracks while they are small stops that sequence. It is routine maintenance, not a repair, and a driveway that gets its cracks sealed each fall can go many years longer before it needs patching or resurfacing.
How Hot-Applied Crack Sealing Works
Preparation decides whether the sealant holds. Each crack is cleaned of dirt, vegetation, and loose material with compressed air or a heat lance, which also dries the crack so the sealant bonds. Cracks wider than about a quarter inch are routed to a uniform width and depth so the sealant has a proper reservoir to sit in.
Rubberized sealant is heated to its working temperature and applied with a wand or pour pot directly into the crack, slightly overfilled, then struck off flush or left with a slight band over the surface. The material stays flexible after it cools, so it stretches as the pavement contracts in winter and compresses as it expands in summer without pulling away from the edges.
Sealant sets within minutes and can take traffic the same day. On a typical Elizabeth driveway the work is done in a few hours.
- Clean cracks with air or heat lance
- Rout wider cracks to a uniform reservoir
- Heat rubberized sealant to working temperature
- Apply, overfill slightly, and strike off
- Open to traffic the same day
Crack Sealing vs. Sealcoating vs. Patching
Crack sealing and sealcoating do different jobs and are usually done together. Crack sealing fills individual cracks with a thick, flexible material so water cannot enter the base. Sealcoating is a thin coating over the entire surface that protects the asphalt from sun and slows oxidation; it will not fill or bridge a crack of any real width. If you only do one in a given year, seal the cracks.
Crack sealing is for cracks that are clean-edged and not yet surrounded by broken pavement. Once an area has alligator cracking, where cracks interconnect in a web, the base underneath has already weakened and the area needs patching rather than sealing. We sort cracks into those two categories during the site visit.

Timing Crack Sealing Around Elizabeth Weather
Crack sealant needs air temperatures of at least 50 degrees and rising, a dry surface, and a dry 24-hour window, which at Elizabeth's elevation generally limits the work to May through early October. The ideal time is September and early October, after the summer heat has let the cracks open to their widest and before the first hard freeze, so the sealant goes into the crack at or near its maximum width and is in place for the entire freeze-thaw season.
Spring is the other workable window. Cracks are narrower then because the pavement has contracted over winter, so the sealant is slightly compressed in summer, but the base is protected through the wet spring hailstorm season. Driveways along Running Creek and in low spots near Gold Creek, where water collects, benefit most from staying ahead of the cracks.
Common Questions
How often should cracks be sealed on an Elizabeth driveway?
Once a year, ideally in early fall, is a good habit. New cracks appear each year as the asphalt ages, and a yearly pass keeps all of them closed before winter. Cracks sealed in a previous year are checked and touched up if the sealant has pulled away.
What size cracks can be sealed?
Hairline cracks up to about an inch wide are good candidates for hot-applied sealant. Wider gaps may need a mastic repair material or, if the surrounding asphalt is broken, a patch. Alligator cracking is not sealed; it is patched because the base beneath it has failed.
Will the sealant be visible?
Yes. Hot-applied sealant leaves a black line along each crack that is darker than the weathered asphalt around it. On a driveway that is also being sealcoated the lines blend in once the sealcoat goes over them. Many owners schedule crack sealing and sealcoating together for that reason.
Is the rubberized sealant different from what I can buy at a hardware store?
Store-bought crack filler is usually a cold-pour emulsion that works for small hairline cracks on a short driveway. Hot-applied rubberized sealant bonds better, stays flexible through more temperature swing, and lasts longer, which matters where the winter freeze-thaw range is as wide as it is on the Palmer Divide.
