PNA's innovative pavement designs allow you to cost-effectively replace asphalt with long-lasting, low maintenance concrete

We can also customize pavement designs within a facility to account for different traffic and load conditions. For example, heavy-traffic truck aprons and loading docks might use a reinforced concrete design with optimized doweling, while the construction of car entrances and parking lots could leverage PNA's patented and award-winning OptiPave system to maximize cost savings.

OptiPave Case Studies

OptiPave System Replaces Asphalt

Concrete is a cost-effective alternative to asphalt, thanks to the OptiPave system offered by PNA. The OptiPave System significantly reduces concrete thickness and construction costs while maintaining equivalent or better performance.

Less Out-Of-Joint Cracking

Concrete curl can be reduced, but it can't be eliminated. In addition, the curl of a slab is more pronounced in a longer slab than in a short slab that experiences the same radius of curl. The OptiPave System uses these principles to minimize mid-panel cracking.

With traditional 12- to 15-foot (3.6- to 4.6-meter) panels, wheel loads apply pressure on both ends of the panel, creating stresses that cause top-down cracking in the middle. OptiPave minimizes these stresses by shortening the panel length to 8 feet or less. This reduces the amount of curl and prevents both edges of the panel from being loaded simultaneously. As a result, the panel experiences less stress and fewer cracks. 

Reduce Construction Costs

By distributing wheel loads over shorter panels, OptiPave allows concrete volume to be minimized while maintaining the same load-bearing capacity. Slab thickness can often be reduced by 2 inches or more, saving up to 30 percent in material costs while expediting placement work. In some cases, base and sub-base materials can also be conserved providing additional savings.
