Challenged by Balanced Mix Design initiatives?

We have an innovative solution. ACE XP™ aramid polymer fiber additive is a technological breakthrough in both asphalt hot mix and balanced mix design.
Easy to use — mix in plant or on site — and lay it, work it, roll it and finish it the same as any other mix. The only difference? Outstanding results in both crack and rut resistance.

ACE XP™ Polymer Fiber  is a true achievement in asphalt additive technology to enhance performance.

To create ACE XP™ Polymer Fiber, Surface Tech binds para-aramid fibers with Sasobit wax. The binder acts strictly as a delivery mechanism; allowing the para-aramid to address the two major distresses affecting asphalt performance today – cracking and rutting. Doing so also dramatically improves the treated roads’ life expectancy. When ACE XP™ is mixed into asphalt, it disperses over 19 million para-aramid fibers throughout each ton of mix to provide three-dimensional reinforcement that increases the asphalt’s resistance to reflective cracking, rutting, fatigue, while increasing life expectancy. And best of all, no specialty contractors are needed for installation. Contractors handle ACE XP™ reinforced asphalt the same way they handle standard asphalt. This underscores the technology that makes ACE XP™ easy to adopt.

Consider the advantages:

  • Manual, semi automated, or fully automated dosing capabilities
  • No change to mix design:  Simply add ACE XP™
  • 30% increase in performance:  All mixes perform at higher PG level
  • Balanced improvement — longer life, with improved crack and rut resistance
  • Small amounts net big results — only 3.4 oz per equivalent ton of mix

Strengthen Pavement. Extend Service Life.

ACE XP™ is a significant achievement in additive technology to enhance asphalt performance.

ACE XP™ Fiber mixed in PG 64-22 hot mix asphalt has been extensively tested based on the Texas Transportation Institute’s Balanced Mix Design Method. The purpose of this testing was to quantify the cracking and rutting performance improvements of ACE XP™ in hot mix asphalt. The results shown below are impressive. By adding ACE XP™ Fiber to the PG 64-22, the cracking resistance significantly improved.

The ease and cost effectiveness of fiber still makes it worth the purchase. Knowing that we have a 37% higher crack resistance is huge.
