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 Thin Concrete Pavement (TCP) system to maximize cost savings.

TCP System Replaces Asphalt

Concrete is a cost-effective alternative to asphalt, thanks to PNA's patented TCP System. TCP 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 TCP 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. TCP 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, TCP 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.
