In the road construction industry, reducing costs, saving time, and increasing performance are essential goals for any project. Fiber-reinforced asphalt mixes offer a compelling solution to these challenges, providing enhanced durability, reduced maintenance needs, and improved performance.
By incorporating high-performance synthetic fibers into asphalt, FORTA® has revolutionized road construction, delivering superior results for both new constructions and rehabilitation projects.
Asphalt roads reinforced with fiber are engineered by incorporating synthetic fibers into the mix, boosting the asphalt’s inherent properties. This integration results in an asphalt composite that delivers superior performance and longevity.
Fiber reinforcement helps to prevent cracking, rutting, and other forms of deterioration commonly associated with traditional asphalt roads by distributing stress evenly throughout the asphalt matrix.
Fiber asphalt road paving offers a range of benefits that make it an ideal choice for modern infrastructure projects. These include:
In the Aldi-Springfield car park and paving replacement project, FORTA-FERRO® 2-1/4″ was used at a dosage of 7.5 lb. / cu. yd. in over 1,300 cubic yards of 6 in. thick pavement, and eliminated over 7,000 linear feet of control-joint saw-cuts. While conventional practice would recommend joint spacing at 12 to 15 ft. for this pavement thickness, the fiber-reinforced pavement expanded the panels to approximately 40 ft. x 40 ft. squares, reducing the saw-cutting volume by approximately 2/3. No major issues were encountered in the mixing, placement, or broom-finish used for the project. In addition to the savings for labor, joint-fillers, and any light temperature-steel reinforcement that might be considered for this type of project, the owners benefit by saving the cost of future joint-related repairs, and gaining additional pavement toughness and durability.
In the past, the City of Orrville, OH, has successfully used FORTA-FERRO® at 4.0 lbs. / cu. yd., for their new city street reconstruction projects. They have successfully eliminated the use of traditional steel reinforcement and the need for placing dowel baskets at the transverse joints. This has resulted in reduced curling at the joints, mid-panel cracking and labor cost savings. By using a dosage of 5.0 lbs. / cu. yd. of FORTA-FERRO® for this project, the transverse joints were extended from 15’ to 30’ with no dowel baskets.
FORTA’s Fiber Asphalt Solutions FORTA leads the industry with high-quality fiber-reinforced asphalt mix solutions designed for both new constructions and rehabilitation projects. FORTA-FI® FORTA-FI is a high tensile strength synthetic mix of aramid and polyolefin fibers engineered to strengthen asphalt’s tensile strength, resilient modulus, and Marshall stability. FORTA-FI is designed for all working temperatures, making it a versatile choice for various applications. SURFACE-EXT® Surface-EXT is an alkali- and acid-resistant glass fiber designed to improve pavement flexibility and long-term durability, ensuring excellent workability and mechanical performance. It is specifically designed to extend the life of micro-surfacing and slurry seal pavement applications. PAVE-AID™ Pave-Aid is a high-performance synthetic fiber blend that reinforces 100% recycled asphalt pavement (RAP) and cold mix asphalt. This fiber significantly improves the rutting resistance of asphalt mixtures, providing three-dimensional reinforcement throughout the entire pavement layer. Pave-Aid offers a cost-effective way to enhance the durability and longevity of RAP applications, providing transportation agencies with sustainable solutions for optimized development.
