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.

PNA's Engineering Expertise

PNA's industry-recognized engineers have focused their academic and professional careers on advancing flatwork design principles and best practices. Beyond concrete design, our engineers are skilled in materials science and geotechnical engineering, as well as construction, maintenance, and repair.

Less Out-Out-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.
