No, FORTA-FI® can be added by the bag, or through one of the various types of fiber feeders,
via the RAP port, or hot bin doors in a batch plant. The fibers should be introduced before the addition of the liquid asphalt.
While the fibers disperse uniformly in seconds, it’s best to allow 3 to 5 seconds of dry mixing time before addition of liquid asphalt.
The use of FORTA-FI® will not require any special plant modifications.
No, FORTAfied® asphalt is placed and compacted exactly as conventional asphalt pavement.
FORTA-FI® is a blend of several different fibers that each play an important role in the reinforcement of asphalt.
The high temperature fibers are among the strongest fibers made, and are only 1/10th the diameter of a human
hair. Some fibers are designed to melt into the asphalt mixture aiding in the dispersion and adhesion of the of the
high-temperature fibers while enhancing both the cold and hot properties of your asphalt design. The combination
of these fibers in the recommended dosage creates significant improvement in tensile strength with over 18
million fibers per ton of asphalt mix.
Research, and our many projects around the world have shown that the recommended dosage of one (1) pound
bag of FORTA-FI® fibers per one (1) ton of asphalt is optimal in most circumstances. While there may be cases
where different dosages may prove to be beneficial, those projects will need to be consulted and verified for each
individual application.
Both the asphalt savings and increased longevity were calculated utilizing performance testing results conducted
by Arizona State University and the Mechanistic Empirical Pavement Design Guide (MEPDG).
FORTA Corporation patented this technology in 1982 and has successfully used fiber-reinforcement in asphalt in
several projects around the world.
Yes, the new packaging assures that FORTA-FI® will disperse uniformly in both batch and drum plants.
Provided the proper production temperatures are maintained, FORTA-FI® will disperse uniformly in seconds at all
production speeds. High percentages of RAP may require longer mixing time.
Immediate cost savings are made possible by reduction in asphalt thicknesses up to 35%. Additional savings are
realized through shorter construction schedules, fewer trucks, fewer lifts, etc.
FORTAfied® asphalt of the same thickness and your conventional asphalt will last more than 50% longer. Longer
life results in less maintenance and resurfacing over the design life of the asphalt.
FORTA-FI® is the newest generation of fiber-reinforcement for asphalt and has been designed for use in all three
types of mixes.
No, FORTA-FI® is typically packaged in a one (1) pound bag per one (1) ton of asphalt dosage (bag and all).
While different bagged dosages are available for batch mixing if necessary, the process still requires no
measuring.
Results and details from our research project conducted by Arizona State University, as well as project profiles,
and DOT pilot projects are available on our website and upon request. FORTA-FI® has had pilot projects in PA,
NY, OH, and GA to name a few but has also been used around the world.
FORTA-FI® fiber mixes three-dimensionally within the asphalt pavement. Woven mats are located underneath the
base of the asphalt pavement. Because cracks can happen anywhere within the asphalt, FORTA-FI® fiberreinforcement
aids in strengthening the asphalt and reducing cracking wherever it may occur. Another advantage of FORTA-FI® is it’s much easier to use.
No additional construction steps equals labor savings!
Yes, less FORTAfied® asphalt is required per job reducing the thickness and/ or better performance
and longer pavement life reducing lifecycle costs, and it can be recycled—RAP.
FORTA Corporation will provide as much information as needed on our materials. Our expertise lies in developing
and producing reinforcing fibers for designed asphalt mixtures or projects.
