Counts come from federal air-permit registrations, and states report to that registry differently. A low count means thin reporting in that state, not that few plants operate there — Alaska and Montana are the clearest examples.

Why asphalt plant distance matters

Most supplier lists sort by name or by state. Neither answers the question that decides whether a plant is usable on a given job: can the mix get there hot, and can trucks keep the crew fed all day?

Mix temperature

Hot mix leaves the plant around 300°F and has to be placed and compacted before it drops to roughly 185°F. Distance is really a temperature budget, and tarps only slow the loss.

Truck cycles

A crew paving continuously needs trucks returning steadily. Doubling the haul does not just add time — it can halve how much you place in a shift, or force you to add trucks to hold the same production.

Plant and scale delays

Distance is only half of the cycle. A busy plant in the morning rush can add 20 minutes at the scale, and traffic through a metro at 7am is not the same road you measured on a map.

Temperature limits, minimum placement temperatures, and haul-time caps vary by state agency and by mix design. Treat the figures above as planning context and work to the specification on your project. To put numbers on the trucking side, the trucking calculator works out cycle times and how many trucks a haul distance needs.

How to choose a hot mix asphalt plant

Distance narrows the list. These are the things to settle on the phone before a haul is scheduled — none of them can be read off a map, and all of them can change week to week.

Mix availability

Confirm the plant actually runs the mix your job calls for, and on which days. A plant a mile away that only runs a base course is no use for a surface lift.

DOT approval

Public work usually requires the producer or the mix design to be on an approved list. Ask before you bid, not after you win — approval is not something you can arrange on the morning of a pour.

Operating hours

Plants fire up for the day's orders, and many northern plants shut down entirely over winter. A 6am start is common; a plant that opens at 8 changes your whole schedule.

Outside sales

Plenty of plants are captive to a parent company and will not load an outside contractor's trucks. This is the single most common wasted phone call in the process.

Pickup and delivery terms

Ask about minimum loads, whether they deliver or you haul, how the scale works, and what account or payment terms apply to a first-time buyer.

Truck access

Check the entrance, turning room, queue length at your intended hour, and whether tarping is required before you leave the yard.

Everything above has to be confirmed with the plant directly. This directory does not hold plant policies, pricing, or approval status, and does not speak for any producer listed in it.

Find hot mix asphalt suppliers near your project

“Plant” and “supplier” are not the same thing. A plant is a production facility. A supplier is a plant that will sell to you — and a significant share of plants are captive, built and run by a paving contractor or a materials group to feed its own crews. Those plants may load an outside contractor when they have capacity, on a limited basis, or never.

Nothing in the public record distinguishes the two, so the listings here should be read as “a permitted plant operates at this location” and treated as a shortlist to call, not as a supplier list. Where a plant has confirmed it sells to outside contractors, the result card says so; where it has not, it says the outside-sales position is unconfirmed rather than guessing.

For most property owners the practical route is the other way round: hire a paving contractor who already has a plant relationship, and use this directory to sanity-check that a supply point exists within a sensible distance of the property.

About our asphalt plant data

The directory holds 3,197 fixed hot mix asphalt plant locations in 2,268 cities across all 50 states, plus DC and Puerto Rico, each at the coordinates of the permitted site rather than a mailing address — a producer's corporate address is often nowhere near the yard your trucks need to reach.

What the records tell you

That a permitted asphalt plant exists at a location, and roughly who holds the permit. Records TPD has researched add the plant's phone, hours, mixes and whether it sells to outside contractors, each shown only where it was actually found.

What they do not

Phone numbers, hours, mix designs and seasonal shutdowns for a registry-only record — and, most importantly, whether a plant sells to outside contractors at all. Plenty are captive to a parent company, and whether a listed plant is operating today is something only the plant can confirm.

Coverage is uneven, because states report differently. A thin result in one state reflects that state's reporting, not the number of plants operating there. Treat this as a starting shortlist to call against, not a verified supplier list — and an empty result means no permit record nearby, not that no plant exists.

Source details and corrections

Plant records are built from US EPA Facility Registry Service data for NAICS 324121 (asphalt paving mixture and block manufacturing). That registry tracks air permits rather than businesses, which is why it covers plants that have no website and no Google listing — common for industrial hot plants — and why it carries no phone numbers, hours or mix lists of its own.

Portable plants are held separately and kept out of the finder and the maps, because their coordinates record where a rig was permitted, not where it is today.

Operate a plant listed here, or know a listing is wrong? Tell us — corrections are how a directory like this gets better than the registry behind it.

Asphalt plant questions

How do I find an asphalt plant near me?

Enter the job-site address — not your office — and choose a maximum haul. The finder asks Google Maps for the drive on real roads, with typical traffic, from that address to the plants around it, and lists them quickest first. Working from the job site matters because the mix has to arrive there hot, so a plant near your yard is irrelevant if the work is 40 miles the other way.

How far can hot mix asphalt be hauled?

There is no fixed limit, because it depends on ambient temperature, load size, whether the load is tarped, and how quickly the crew places it. As a planning figure, most contractors treat about an hour as comfortable and start managing the risk carefully beyond about 90 minutes. Cold weather, small loads, and delays on site all shorten that. Your mix supplier and the project specification are the authorities here, not a general rule.

What is a hot mix asphalt plant?

A facility that heats and dries aggregate, combines it with liquid asphalt binder in measured proportions, and discharges the finished mix hot for immediate delivery. Plants are either fixed installations or portable rigs set up near a large project. Both types produce mix to a design; the difference is whether the plant stays put.

Is an asphalt plant the same as an asphalt supplier?

Not always. Every plant produces mix, but not every plant sells it to outside buyers — many are owned by a paving contractor or a materials group and run primarily to feed that company's own crews. A supplier is a plant that will sell to you, on terms you can work with. That is a commercial question no public dataset answers, so it has to be confirmed with the plant directly.

Can homeowners buy hot mix asphalt directly from a plant?

Sometimes, but it is rarely practical. Plants sell by the ton with minimum loads, expect a suitable truck, and will not advise on placement. Hot mix also has to be spread and compacted within a narrow temperature window, which is difficult without a crew and a roller. For a driveway, hiring a paving contractor who already has a plant relationship is almost always the better route — cold patch is the usual product for small homeowner repairs.

What should I confirm before sending trucks to an asphalt plant?

That the plant is running that day, that it has your mix, that it will sell to you, what the minimum load and payment terms are, how the scale and loading work, and how long the queue is likely to be at the hour you plan to arrive. Confirm it by phone — plant schedules change with the weather and with the orders already booked.

Why does asphalt plant distance matter?

Because hot mix is perishable and trucking is a real line item. Longer hauls mean lower mix temperature on arrival, longer truck cycles, more trucks needed to keep a crew paving, and more exposure to traffic and plant queues. A cheaper price per ton from a distant plant frequently costs more once trucking and lost production are counted.
