Hot Mix Asphalt vs. Cold Patch: When the Bag Works and When It Does Not, From Alec's Asphalt Paving in Little Rock

A bag of cold patch sits near the register at the hardware store, and it looks like an answer to the hole in the driveway. Sometimes it is. For a few cold weeks it is a fair answer. For the long run it is not.

Cold patch is a temporary fix, and hot mix is the lasting one. The Minnesota Department of Transportation says cold mix "should only be used for temporary fixes in small to medium potholes." Alec's Asphalt Paving, a family-owned Little Rock company started in 2015, handles asphalt repair and patching and gives free written estimates.

What does cold patch do in winter?

MnDOT's "Asphalt Patching Methods Best Practices" poster, drawn from its Research Report 2017-25, is plain about the limits. Cold mix "is not designed to be structurally sound for depths beyond 2 inches," and a deeper patch should go in two lifts, compacted separately.

For cold mix, the same poster calls manual placement with shovels the preferred method, with compaction after each lift when a patch is deep.

The calendar matters too. Tennessee DOT said in February 2025, "Cold mix asphalt is currently being used for temporary repairs." Permanent repairs come "in spring and early summer when asphalt plants are producing ample amounts of hot mix." Winter patching is partly a plant-schedule problem, not only a skill problem.

Why do winter patches fail?

A lasting patch starts with a clean, dry hole. MnDOT recommends compressed air to remove "dirt, debris, and any standing water." For hot mix patches it calls for "complete coverage of the patch area with an approved tack material." It adds, "Compaction should be as thorough as possible to ensure patch longevity," and names vibratory steel rollers.

A bag shoveled into a wet January hole and tamped by a boot gets little of that. MnDOT notes that cold mix is generally an off-season method. Since it is a temporary solution, the poster says, "the abatement of moisture is of less concern."

What does hot mix do that the bag cannot?

MnDOT calls virgin hot mix asphalt, used in the regular season, "the most acceptable option." It adds that "HMA works for any depth repair; however, when the patch depth exceeds four inches, multiple lifts should be considered, with compaction taking place after each lift."

So when a hole is deep, wide, or in a wheel path, the lasting repair is hot mix asphalt, cut clean, tacked, and rolled in lifts. A hand-tamped bag cannot do all three.

When is cold patch a fair choice?

  • The hole is small and shallower than 2 inches.
  • It is winter, and hot mix is not available yet.
  • The hole will catch a tire or an ankle until spring.
  • You treat it as a placeholder and plan the real repair.

When should I call for hot mix?

  • The hole is deeper than 2 inches or has opened again after a patch.
  • It sits where wheels run every day.
  • Alligator cracks surround it, a sign the base under the asphalt may have failed.

On my deliveries, a loaded truck finds a failed patch quickly, and so do the neighbors' tires.

What should a patching estimate say?

A hole is usually a symptom. Water gets under the asphalt, the base weakens, and traffic does the rest. So a good estimate for a patch names more than a price:

  • the size and depth of the repair
  • the method, hot mix or cold mix
  • whether the base under the hole is being repaired or only covered
  • how the edges are sealed against water

Alec's Asphalt Paving gives free written estimates, and its phone line is "Available 24/7. Press 1 and you'll reach a person."

What is a sensible plan for the season?

  • Winter: Sweep out loose stone and standing water, fill the hole with cold patch in layers if it is deep, and note where it is.
  • Spring and early summer: Ask for hot mix once plants are producing it, the timing Tennessee DOT gives for permanent repairs. Get a written estimate that names the repair method.
  • Afterward: Watch the patch edges. MnDOT says a hot mix patch needs sealant or tack at the contact point "to keep infiltrating moisture out," and a seam that opens is where water gets in.

What does a lasting patch cost?

Typical Arkansas ranges for asphalt repair and patching run about $3 to $15 per square foot, and most single potholes fall between $150 and $600. These are market ranges, not Alec's price list, and the final number depends on the job.

Questions people ask

Can I use cold patch now and call for hot mix later? Yes. That is the order DOTs follow too: cold mix in winter, hot mix when plants reopen.

How Much Asphalt Do I Need for My Driveway in Little Rock? Two Measurements, One Formula, and the Written Quote From Alec's Asphalt Paving

Image
Take two measurements with a tape: the length of the driveway and its width, both in feet. If the width wanders, measure the narrowest and widest points and average them. Write the numbers down before anyone starts talking tons. Tons of asphalt equal square yards, times pounds per square yard per inch, times inches of compacted thickness, divided by 2,000. Your tape gives the square yards. The written quote gives the real quantity. Alec's Asphalt Paving, a family-owned Little Rock company started in 2015, gives free written estimates, and its website, alecsasphalt.com , is where to ask for one. Step 1: Turn feet into square yards Multiply length by width for square feet. Divide by 9 to get square yards, since one square yard is 3 feet by 3 feet. A 12-foot by 40-foot driveway is 480 square feet, or about 53.3 square yards. I will use that driveway for every number below. Step 2: Find the weight per square yard per inch The Tennessee Department of Transportation shows how a DO...

Asphalt Millings vs. New Asphalt for a Driveway: When Each Makes Sense, From Alec's Asphalt Paving in Little Rock

Image
Dump a load of asphalt millings in a driveway and what you see is dark gravel: crushed pieces, black at the edges, loose underfoot. Nothing about day one says pavement. What matters is what that pile becomes once it is spread and packed, and whether new hot mix is the better buy. Asphalt millings are old pavement, ground up and reused, and a driveway made of them behaves more like bound gravel than like new asphalt. For a long, low-traffic lane they can make sense. For a smooth, sealed driveway meant to last, new hot mix is the better buy. Alec's Asphalt Paving , a family-owned Little Rock company started in 2015, handles asphalt paving and installation. Ask whether millings fit your job. What are asphalt millings, exactly? The Federal Highway Administration defines reclaimed asphalt pavement, or RAP, as "removed and/or reprocessed pavement materials containing asphalt and aggregates." Milling is one way the old surface comes out: "Milling entails removal of the...

Tree Roots Lifting Asphalt: What a Repair Can and Cannot Fix, With Alec's Asphalt Paving of Little Rock

Image
The bump you feel at the curb comes first. A dolly's wheels catch where the driveway apron meets the street. The asphalt edge sits higher than it did last year, and the surface looks pushed up from below. On my appliance route around central Arkansas, the nearest tree is the first suspect. Tree roots lift asphalt because they thicken as they grow and push upward against the pavement over them. A repair can cut out the raised section and make the surface level again, but it cannot stop the root from growing. Alec's Asphalt Paving, a family-owned Little Rock company started in 2015, does asphalt repair and patching, including level corrections. Why do roots lift pavement? Iowa State University Extension and Outreach explains it in a page by Aaron Steil and Jeffery Iles, last reviewed in July 2024. "As roots expand, they can push up sections of the sidewalk, resulting in buckling and lifting," it says. Roots can also enter small cracks and widen them. Purdue Extensi...
