What is PressurePave?

The patented PressurePave® system is one of the most versatile tools in the pavement preservation industry. Able to preserve pavements many would consider to be candidates for mill and overlay, this hybrid system pressure-injects a crack sealant into pavement while simultaneously applying a durable thin asphalt overlay.

This system is more efficient and cost effective than many other pavement preservation options. With a price that can be significantly less than the cost of a mill and asphalt overlay, and a 15-year average surface life, the life cycle cost is ideal for public and private agencies wishing to cut costs or double the amount of roadways they are able to treat.

Whether it is a residential street or busy arterial, the time it takes to repair/resurface and return roadways back to normal traffic flow is extremely important to the public. With PressurePave®, one simple application accomplishes what would historically require multiple products, processes and traffic disruptions. The chemical reactions within the PressurePave® materials enables a resurfaced pavement to be ready for initial traffic flow usually within 30 minutes.

The Sealant

Many times, when surface treatments are applied over cracked streets the cracks reappear within the first one to two years. This cracking can be slowed but never stopped even with the application of the MAQS® surface. But if the PressurePave®'s more ductile and crack resistant sealant is present the base pavement will remain sealed.

Specifically engineered to fill small “hairline” and large transverse/longitudinal cracks while traveling at 6 feet per second, the pressure-injection system is capable of coating the entire surface with a ductile and highly water-resistant membrane. This membrane is chemically engineered to remain ductile in cold temperatures and tough in the heat. If this membrane were to crack, it is designed to be able to self-heal with the application of heat and pressure (traffic).

Is PressurePave Right For My Streets?

PCI Rating of 40 and Above

PressurePave® is designed to treat pavements that are normally not suitable for conventional pavement preservation methods such as hot rubber crack seal, slurry, microsurfacing, and seal coat.

This system allows agencies to extend the life of pavements in poor condition without having to pay for a full mill and overlay.

In technical terms, pavement preservation products are generally designed to treat surfaces with a Pavement Condition Index (PCI) of 80 and above. PressurePave changes that, allowing agencies to preserve pavements as low as 40 (assuming no subgrade issues).
