ACE Fiber® (Kevlar) adds 3D strength to asphalt!

Small hair-like fibrils “root” into asphalt

Many fibers have been successfully used to reinforce concrete, but it takes a special fiber to successfully reinforce 350 degree asphalt. Aramid is a unique fiber with 400,000 psi tensile strength and micro-roots that tenaciously anchor themselves in asphalt. In the summertime when asphalt gets hot and wants to rut, the rooted aramid provides resistance to the “flow” of asphalt to mitigate rutting. In the wintertime when asphalt is cold and wants to shrink, aramid provides added tensile strength for resistance to cracking. The bottom line…fibers in asphalt now make sense because of aramid, and for relatively low cost aramid fiber makes a big performance improvement in asphalt.

ACE Fiber®, is pure aramid with a wax treatment. By treating the aramid with wax, the aramid is weighted down and controlled for proper delivery into the asphalt mix. When ACE Fiber enters the asphalt mixing chamber, the wax melts to release the fibers in the right place at the right time. This unique delivery process results in the highest performing blend of Fiber Reinforced Asphalt Concrete (FRAC) in the market. Any asphalt project can benefit from ACE Fiber® including both newly constructed asphalt pavements as well as thin asphalt overlay projects over deteriorated asphalt or concrete pavements.

ACE Fibers are high performance engineered fibers for asphalt that increase service life, save costs, or a combination of both.  Similar to different fibers used in concrete for decades, Aramid fibers are now used in asphalt to significantly increase performance of new asphalt pavements and overlays.  Aramid fibers are 5 times stronger than steel and add strength to asphalt pavement in all directions.

When ACE Fiber® is mixed into asphalt, it disperses over 19 million aramid fibers throughout each ton of mix to provide 3-dimensional reinforcement that increases the asphalts resistance to reflective cracking, rutting and fatigue.  And best of all, no specialty contractors are needed for installation!  Contractors handle ACE Fiber® reinforced asphalt the same way they handle standard asphalt.
