Longer Life

AQU FIBER is a true achievement in additive technology to enhance asphalt performance.

To create AQU, Surface Tech engineered and developed a fiber additive to address the 2 major distresses effecting asphalt performance today, cracking and rutting. Not to mention dramatic life expectancy improvement.

When AQU 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, fatigue and increased life expectancy. And best of all, no specialty contractors are needed for installation. Contractors handle AQU Fiber reinforced asphalt the same way they handle standard asphalt.

How it Works

How does AQU FIBER make asphalt more durable?

Many fibers have been successfully used to reinforce concrete, but it takes a special fiber to successfully reinforce warm mix 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.

Technology Behind AQU Fiber

AQU Fiber, is pure aramid. By binding the aramid with water, the aramid is weighted down and controlled for proper delivery into the asphalt mix. When AQU Fiber enters the asphalt mixing chamber, the water disspates 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 AQU Fiber including both newly constructed asphalt pavements as well as thin asphalt overlay projects over deteriorated asphalt or concrete pavements.

50% Increase in rut resistance
150% Increase in strength
140% Increase crack resistance
290% Increase in fatigue life
150% Increase in thermal crack resistance
The aramid is weighted down and controlled for proper delivery into the warm or cool asphalt mix (WMA)
The water dissipates to release the fibers in the right place at the right time
Provides superior, thorough disbursement of aramid into the mix

Material Properties

Aramid Fiber Reinforcement. Provide AQU Fiber (pre-treated para-aramid reinforcing aramid fiber) conforming to the requirements below. Design asphalt mix without fiber and do not alter the final mix design for the addition of fiber at the plant. Use the dosage rate of 2.8 oz. coated weight per ton of asphalt mix (of which 2.1 oz. is pure aramid). The fiber addition tolerance allowed shall be no less than 2.8 oz. coated weight (2.1 oz. pure aramid) and not more than 5.3 oz. coated weight (4.0 oz. pure aramid) per ton of asphalt mix. Please note that AQU Fiber contains 75% actual aramid fiber and 25% water binder, by weight. This pretreated para-aramid (water bound) fiber remains in the form of a fiber strand with over 10,000 individual fibers / strand that is easily conveyed to the asphalt mixing drum. In the mixing drum, the water evaporates allowing the dry fibers to disperse into the asphalt mix.

Use Less, Save More

Up to 33% reduction in asphalt thickness (at $60/ton for asphalt, you are saving $20 which covers the cost of AQU)
This savings still compares/equates to control life of road; covering ACU, saving additional dollars AND improving life expectancy is a major Value Proposition.

Engineered for Performance


AQU 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.
