NCAT announced the finalized publication of NCAT Report 18-04, Phase VI (2015-2017) NCAT Test Track Findings. Six cycles of research have now been completed at the NCAT Test Track, and the findings have helped sponsors refine their materials specifications, construction practices, and pavement design procedures for asphalt pavements.
The research topics and objectives of experiments conducted in the sixth research cycle include: cracking tests, porous friction course, bio-based rejuvenator, enhanced friction surface, softer binder for high RAP mix, stress absorbing interlayer, longitudinal joints and durability, high RAP thin overlay, friction and bond strength, 4.75mm thin overlay, cold central plant recycling and full-depth reclamation.
