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.
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 BetterStreet 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.

“Hearing about RockAsphalt, the first thing I thought was "not in Michigan." […] Wrong. It's been outstanding and if it survives the winters up here, it survives anywhere.”
