Amarillo Pavement Pros: What Commercial Asphalt Paving Costs in the Texas Panhandle

Why this page exists

Most paving contractors will not put a number on a website, and the reasons are reasonable enough. Every lot is different. A published figure gets compared to a different contractor’s figure for a different scope. Prices move with oil, because asphalt binder is a petroleum product.

None of that helps a property manager who has been asked to budget for the parking lot next year and has no idea whether the answer is twelve thousand dollars or a hundred and twenty thousand.

So here are working ranges, drawn from published regional rates for commercial asphalt work, with the variables named so you can see which end of each range your property sits at. These are not quotes. A quote comes from somebody walking your lot. They are for working out the order of magnitude.

The single question that moves the number most

Before any square footage arithmetic, there is one question that matters more than all the others: is the base still sound?

Asphalt work divides into two cost worlds.

Surface work treats the pavement you can see. Crack sealing, sealcoating, striping, surface patching and overlay all live here. Nothing is excavated, nothing is hauled away in quantity, and the numbers are modest.

Structural work replaces what is underneath. Full-depth patching, reconstruction and anything involving excavation live here. Material comes out, goes to a landfill or recycler, new base goes in and gets compacted, and then paving happens on top. The numbers are several times higher.

A ten thousand square foot lot might be a $24,000 job or a $120,000 job, and the difference is almost entirely whether water has got into the base yet. That is why the diagnosis is worth more than the shopping around, and why the first question on any job is whether the lot is an asphalt overlay candidate at all.

Working ranges by type of work

Work	Range	Notes
Crack sealing	$1.00 to $3.00 per linear foot	Routing, cleaning and hot-pour. Priced by crack length, not lot area
Sealcoating	$0.18 to $0.35 per sq ft	Two coats. Excludes crack sealing and restriping
Surface patch, sound base	$2.50 to $5.00 per sq ft	Asphalt replaced, base left alone
Overlay, structurally sound lot	$1.75 to $3.50 per sq ft	New lift over existing surface, no milling
Mill and overlay	$2.25 to $5.00 per sq ft	Milling adds roughly $0.50 to $1.50 per sq ft over overlay
New asphalt, prepared site	$3.00 to $6.00 per sq ft	Paving only, where base and grading already exist
Full-depth patch	$6.00 to $12.00 per sq ft	Saw cut, excavate, rebuild base, repave
Full-depth build or reconstruction	$8.00 to $15.00 per sq ft	Excavation, base, drainage, paving

And by whole project, for a typical ten thousand square foot commercial lot:

Project	Range
Sealcoat and restripe	$2,400 to $5,200
Mill and overlay	$22,000 to $50,000
New lot, prepared site	$35,000 to $95,000
Full reconstruction	$80,000 to $150,000

What moves you within a range

Thickness. An overlay at one and a half inches and one at two and a half inches are different quantities of material, and material is a large share of the cost. Thickness should be set by the traffic, not by the budget, but it is worth knowing it is a variable.

Milling. Adding a mill to an overlay costs roughly $0.50 to $1.50 per square foot. It is not optional where raising the grade would bury a curb, block a drainage inlet, or create a lip on an accessible route, and it is the only way to correct ponding while resurfacing.

How much patching happens first. An overlay is priced on the assumption that the surface underneath is sound. Every square foot of full-depth patching needed before the lift goes down is priced at the structural rate, not the surface rate. A lot needing fifteen percent patching is a materially different job from one needing none.

Access and phasing. A lot that can be closed entirely and paved in one operation is cheaper than the identical lot that has to stay open, be worked in six sections, and have traffic managed around it. On occupied commercial property that is often unavoidable, and it is worth knowing you are paying for it.

Size. Mobilisation, traffic control and setup are largely fixed costs. Spreading them over forty thousand square feet gives a much better unit rate than spreading them over four thousand.

Drainage work. Correcting fall, resetting an inlet or adding drainage structures sits outside the per-square-foot paving rate. A localised re-grade commonly runs $3,000 to $9,000 and adding or resetting an inlet $2,500 to $8,000.

Accessibility work. Bringing an accessible space, its aisle and its signage to standard commonly runs $250 to $600 per stall where it is a striping and signage matter. Where the space has settled out of tolerance and needs re-grading, it is $1,800 to $6,500, because that is pavement work rather than paint.

The cost of waiting, which is the real number

Pavement does not hold its price. It moves between the cost bands above on a timetable set by water and weather.

A lot with open cracks admits water. Water reaches the base. The base softens, the surface starts flexing beyond its limit, and it fatigues into alligator cracking and then potholes. At that point the lot has moved from the surface-work band to the structural band, and the cost has multiplied.

In this region that clock runs fast. NOAA engineering weather data records about 85 freeze-thaw cycles a year for Amarillo. Every one of those takes water sitting in a crack, freezes it, expands it, and levers the crack wider. A crack that would sit stable for years in a mild climate progresses here in a season or two.

That is the arithmetic that should drive budgeting. Crack sealing a ten thousand square foot lot might be $1,200 to $4,500. Letting those cracks run until the base fails turns the same property into an $80,000 to $150,000 reconstruction. The cheap work is not cheap because it is trivial. It is cheap because it is done early.

The same pattern holds across the service area. Commercial property in Canyon, twenty minutes south, sits on the same caliche under the same thermal load, so the arithmetic above transfers without adjustment.

How to compare bids without being misled

The most common reason two paving bids differ by a factor of two is not that one contractor is expensive. It is that they have priced different work.

Insist that every proposal states the area in square feet, the lift thickness, the milling depth if any, the quantity and location of full-depth patching included, what happens to the markings, and what is excluded. With those numbers you can compare bids. Without them you are comparing two lump sums for two unknown scopes.

And treat an unusually low bid as information rather than a bargain. The two easiest places to save money on a paving job are base preparation and compaction, and neither is visible on the day the job finishes. An under-compacted mat looks exactly like a properly compacted one and fails years earlier.
