NCAT Test Track

Opelika, AL - 2012

Project Description

The National Center for Asphalt Technology (NCAT) just outside of Auburn, Alabama, is a world leader in asphalt research. NCAT is most commonly known for their renowned test track that utilizes accelerated pavement testing (APT). During each testing cycle, 10 million ESALs (about 10 years worth of traffic) can be applied to the track in only 2 years. FORTA-FI® is featured in a Porous Friction Course (PFC) mix in section E9B which was sponsored and funded by the Alabama DOT when it was placed in 2012.


In March 2018, Buzz Powell presented the NCAT conference regarding the FORTA section on the test track. After 6 years down and 20 million ESALS, our fiber section has no noticeable cracking, .01 in. of rutting, and no raveling with no changes in macrotexture. Due to this success, Alabama DOT and NCAT have decided to put this section through another cycle consisting of 3 more years and 10 million more ESALS.

Key Points

  • Extended Pavement Life
  • Reduced Rutting & Raveling
