North American Green

Independent Product Testing

Continued, large-scale research establishes and defines the performance values of our products. And physical property testing ensures that our products perform successfully under actual field conditions.

North American Green has the utmost confidence in our product quality, and submits our entire line of products to random quality testing by the National Transportation Product Evaluation Program (NTPEP) of the American Association of the State Highway and Transportation Officials (AASHTO).

In this test protocol, an unbiased ASSHTO representative selects our products at random from warehouse stock, and ships them to a laboratory. There, independent, third-party physical property and bench-scale tests are performed. NTPEP testing is considered the ultimate example of a company’s confidence in its products.
