Perpetual pavement is a multi-layered paving process that creates a smooth riding experience, has all the safety advantages of asphalt, but when combined with routine maintenance, lasts much longer than standard asphalt.

If properly maintained and rehabilitated, Perpetual Pavement can be designed and built to last longer than 50 years without requiring major structural rehabilitation or reconstruction, and requires only periodic surface renewal in response to distresses.

The key to its success is a strong foundation.

Perpetual pavement has two foundational layers. Beginning with a stress resistant, flexible base that protects against cracks from forming in the bottom of the pavement.

On top of the base layer is the Intermediate Layer which completes the structural portion of the perpetual pavement.

The final layer is generally a rut-resistant hot mix asphalt. Because of its durability, Perpetual Pavement can go many years before requiring maintenance, which cuts down on traffic disruptions, reconstruction and repair.

How it works.

The key challenge perpetual pavement overcomes is the elimination of bottom-up fatigue cracking. During cyclic traffic loading, the bottom layer of the pavement layer becomes fatigued from induced strain. Cracks can develop and then propagate into the upper layers, eventually making their way to the surface.

Perpetual pavement uses a mix resistant to rutting and thermal cracking. Creating a pavement designed to be strong enough to keep traffic-induced strains at or below the "endurance limit” practically eliminating cracking altogether.

How it saves money.

Perpetual Pavement doesn’t require a full re-construction down to the foundational layer. It generally only requires a top level repair, which means over time, less money is spent on materials and repair.

Short History of Perpetual Pavement.

Full-depth and full-strength asphalt pavements have been constructed for decades, and continue to perform well
Remember Asphalt is recyclable. And when recycled asphalt is used in a Perpetual Pavement project, it can be potentially saving you up to 30% over non-recycled asphalt.
