Used to pave roads for over a century, RockAsphalt© has now been reengineered for all-weather pavement repair. Learn why our unique natural asphalt costs less and outlasts manufactured mixes.

The Fundamental Problem

What Makes Pothole Repair Expensive? Time & Labor

In a world where public works budgets are tight and road crews are stretched thin, every dollar matters. Yet consider all the hidden costs involved in the typical pothole repair as described on the rightbelow.

Or Learn A Better Way

Wait For Weather

Crews work around the weather because both cold and hot mix are either unworkable or unreliable outside a particular range of temperatures and moisture levels.

Drive To Plant

Once the weather is acceptable, a crew drives to an asphalt production plant to pick up compactors, sprayers, mixers, and other tools along with the material.

Prep, Patch, & Wait

The crew then drives all the way back to the location of the pothole, blocks off traffic, and begins to prep. After they finish patching, the crew waits until the asphalt is ready for traffic.

Evaluate, Then Repatch

A few months later, a supervisor revisits the pothole site to evaluate the repair. Most patches will already show signs of distress and will need to be repaired again next season.
A Better Solution

Natural RockAsphalt© 

Now For Pothole Repair

Less Failed Patches

Apply pressure and our one-of-a-kind native asphalt rocks secrete concentrated bitumen and fuse tightly together. Warranty-backed for an industry-leading 3-years after installation.

Less Waiting On Weather

Immediately binds on compaction in -40° to 168° F and in water-filled holes. Forms a flexible but permanent bond with surrounding pavement and without weather-sensitive additives.

Less Liability And Risk

No exposure risks or health liabilities from hazardous chemical additives. Our naturally occurring asphalt material is 100% VOC-free, enviro-friendly, and safe for workers.

Less Prep And Waste

Just throw-and-roll. No special tools, site prep, or multi-person crews required. Shipped directly to you (at no extra cost) in 50lb bags preventing wasted material and long drives.


More Coverage Per Pound Than Other Leading Patches

The secret to our cost-reducing, industry-best coverage (.012ft3/lb) is the native asphalt we mine in Texas. Ready to learn more about our unique material?

Warranty-Backed Durability

Guaranteed to last at least 3 years after initial installation

Why It's Reliable

Street Superintendent Jay Perez On How He Found Out About RockAsphalt©

“When I first came onboard I noticed we had ten high AADT intersections but only one that wasn’t giving us trouble. […] After asking around, I realized the crew had used a different patch. Frankly it’s [RockAsphalt] been our go-to ever since. It stays put and makes our job easier. I like that.”

How Native RockAsphalt© Is Different

Most hot or cold mix asphalt is a manufactured combination of distilled crude oil and rock. Basically it’s just gravel covered in an oily glue. Our asphalt on the other hand? Well it took nature over 150 million years to make it.

Since the Cretaceous period, pressure has been causing viscous bitumen to impregnate the Anacacho limestone deposit we mine in South Texas. That means the adhesive that binds our asphalt together has slowly seeped deep inside the rocks. And that matters if you want a durable, heavy-duty pothole patch.

The Problems With Manufactured Asphalt

With manufactured mixes, only the surface of the rocks are covered with a binding glue. That’s why most asphalts are either difficult to use or wear out quickly when the weather turns bad. That’s also why most asphalt dries out rapidly and requires special equipment.

In contrast, a binding glue permeates the rocks in our native asphalt. That’s why all it takes is compaction and our bitumen-bearing limestone rocks fuse together into a dense and durable surface. In fact, the more pressure, the more tightly bonded our self-priming asphalt gets.

Inconsistent Production

Easily contaminated materials and poorly produced materials reduce longevity

Depends On Chemical Additives

Long-term health risks and liability from VOC’s and hazardous solvents

Difficult To Use

Requires special equipment and training. Leaves a tarry mess.

Unreliable Performance

Unstable at different temperatures causing migrating and shrinking as it cures

Mined & Produced Outside Of San Antonio, Texas

Family Owned & Operated For Over Five Generations

Time-Tested, Proven Performance

There’s a reason state DOT’s and municipalities have trusted RockAsphalt© on highways, runways, and other critical infrastructure since 1895.

Exceeds Industry Standards
