• REARM HR™ — Tougher pavement. More RAP. No cost increase. (Oct 20, 2021)

  Hall Paving in Louisville, KY, recently discovered the sweet spot for using more RAP while keeping costs in line with traditional low-RAP pavement mixes. It’s a new development from Surface Tech called REARM HR™, the combination of a highly engineered bio-oil and aramid fibers that allows up to 50% RAP usage. This REAM HR™ project utilized the following in the 3/8” 5 NMAS; 5.6% PG64-22 total AC mix design:

  Lampton Avenue Project — 10-14-2020

  • 36% RAP (recycled asphalt pavement)
  • TUFFTREK 4007
  • ACE XP POLYMER FIBER™ from Surface Tech

  

  A total of 900 tons was produced for the three-mile project. Hall Paving succeeded in developing a mix design that added ACE XP POLYMER FIBER™ to every ton of asphalt at a neutral cost. The mix also increased the percentage of RAP over the standard 20% RAP design, while maintaining the cracking and rutting performance of lower RAP % mixes.

  ACE XP POLYMER FIBER™ aramid fibers strengthen the asphalt mix by providing increased tensile flexibility, which improves both cracking and rutting performance. TUFFTREK 4007 softens the virgin binder to compensate for the aged binder from the higher percentage RAP content. The resulting pavement resists rutting in hot weather and cracking through cold winters.

  

  Final analysis: Pavement that lasts longer and requires less maintenance over its life span. In other words, the same up-front cost + lower maintenance costs = Big Win.

  “Hall Paving was extremely excited about the way the mix went down and compacted,” said Joe Dennis, Surface Tech’s Chief Technical Officer for Asphalt. And the City was blown away by the look and performance going down. It’s really a smooth roadway.”

  

  This mix was under the microscope! Blankenship Asphalt Tech and Training (BATT) assisted Surface Tech in testing and developing the successful formula and verified the mix with Hamburg Wheel Tracker and IDEAL-CT testing for rut and crack resistance. Surface Tech provided quality control support on site during production. S&ME was also on site to check overall quality on behalf of Louisville Metro.

  Hall Paving used a pump system for adding TuffTrek 4007 from totes in line with the PG64-22 asphalt binder and dosed the ACE XP POLYMER FIBER™ into the HMA plant using Surface Tech’s Automated Micro Doser – MD3+. All parties agreed, the results were outstanding.

• Tougher and under budget — with no ruts or cracks after three years! (Oct 20, 2021)

  City of Brooks finds ACE XP Polymer Fibers a good value for asphalt paving

  n 2018, The City of Brooks in Alberta, Canada, needed a new pavement solution for a problematic intersection with a tendency to form ruts. In a leap of faith, Brooks Asphalt and Aggregate, along with the city’s public works officials, decided to try adding ACE XP Polymer Fibers® to a 75mm mill and replacement overlay project on a 1600-meter, or approximately one-mile section of Cassils Road, including a busy intersection.

  ACE XP Polymer Fiber® was relatively new in Alberta at the time, but the reputation of aramid fiber, which forms the base of the product, is well established. As one of the strongest man-made materials in existence, aramid fibers provide tensile strength and durability to underwater cables, bullet-proof vests and many other products. Given this fact, city engineers wondered, “Could it also make pavements stronger and last longer?”

  The answer is “YES!” Three years later, the town’s major roadway shows no signs of rutting or cracking, and city officials anticipate the new pavement will last 30 years — a 10-year life extension.

  Better yet, Brooks Asphalt and Aggregate found adding ACE XP required no changes to the mix, and Surface Tech’s automatic dosing system ensured a reliable, quality end product.

  As a welcome bonus the project also came under budget, proving that ACE XP Polymer Fiber® not only provides excellent value on the front end, but also lasting value in terms of less cracking, reduced rutting and longer pavement life.
