CASI chose to partner with EZ Street asphalt in 2008. EZ Street asphalt is an international product that is used for various applications including pothole patching, utility cuts, trench repairs and even paving in several countries.

In Colorado, they don’t say “cold patch asphalt” anymore. They say, “EZ Street”.

CASI is proud to produce EZ Street asphalt, a polymer-modified cold mix, fine-tuned to work in Colorado’s melodramatic climate.


And, it’s minimally invasive. Just sweep, fill, and compact. EZ Street repairs are instantly ready for traffic, so lanes can be re-opened as soon as the repair’s filled.


EZ Street asphalt is designed for:
• Potholes
• Utility cuts
• Small overlays
• Catch basins
• Manhole surrounds
• Edge repairs
• And more

But, it’s not just how it works, there’s something remarkable about how EZ Street stockpiles stay fresh.

When left in bulk bins, EZ Street asphalt forms a coating that protects the pile, and easily breaks up for use, without any further treatment.

That allows Colorado public works and construction yards to keep EZ Street mix on hand for quick access during emergency calls.

Bulk storage. Guaranteed one-time repairs. Small crews. No need to heat. It all adds up to saving money, while making Colorado roads safer.

CASI produces EZ Street asphalt year-round. It’s available in:
• Loose bulk by the ton
• One-ton bulk sacks
• 50 lb bags  

Once you try EZ Street asphalt, everything else is just cold patch.

Sweep. Fill. Compact. Save.

EZ Street repairs are an investment—they pay you back. A one-person crew and
a truck load of EZ Street cold patch is all it takes. And, it only takes once.

Less labor, less weather-related delays, and an ease of use—from workability to durability—it all adds up to less money out and more money in.


Ready when you are:
Like a trusted Labrador, EZ Street asphalt’s ready to go whenever you are. It doesn’t even need much of a home.
EZ Street high performance cold patch is designed to be stockpiled for up to a year inside, or exposed to the elements—even in the Rockies. So, when hot mix plants are down, EZ Street’s ready—and guaranteed workable.


Storability = Efficiency

EZ Street cold patch is safer than hot mix; it requires practically no training; and crews can keep a 50 lb bag or two in their trucks for impromptu repairs, cutting down on special trips. That all adds up to less drive time, less equipment, and faster, budget friendly repairs.

CASI & EZ Street Partnership

CASI chose to partner with EZ Street asphalt in 2008. EZ Street asphalt is an international product that is used for various applications including pothole patching, utility cuts, trench repairs and even paving in several countries.


CASI is a producer of EZ Street® asphalt, the only permanent cold asphalt. EZ Street® is a polymer-modified asphalt specially formulated to work in all weather conditions and temperatures. It can also be used in water, such as in water-filled potholes. With EZ Street® cold mix asphalt , repairs can immediately be re-opened to traffic, eliminating long delays and traffic congestion.

It’s designed for use on potholes, utility cuts, small overlays, catch basins, manhole adjustments, and edge repairs in asphalt and pavement applications. EZ Street® is formulated to improve cohesion, adhesion, and water resistance. And it’s guaranteed permanent.

In Colorado’s wet, cold, and freeze-thaw cycle, EZ Street® cold asphalt is the material of choice. Because EZ Street® has tack coat built in and is cold, crews can be rapid first responders to any pothole or utility main break repair—even if it’s snowing. EZ Street® remains workable even when it’s stockpiled. Colorado public works and construction yards can access EZ Street® asphalt for immediate repairs: day or night, winter or summer. Because the cold asphalt can be installed and used immediately, repairs can be addressed with minimal traffic impacts in any season. CASI produces EZ Street® year-round. It’s available in loose bulk by the ton, one-ton bulk sacks, and  50 pound bags.
