Today, many asphalt paving contractors choose FORTA-FI® for fiber reinforced asphalt installation: "FORTA-FI® is a high tensile strength synthetic fiber blend formulated to reinforce asphalt mixes in both new construction or rehab projects. The mix of aramid and polyolefin fibers is designed to enhance your current mix design.
The purpose of the test method is to determine the amount of recovered fiber from fiber reinforced asphalt concrete (FRAC). The test method utilizes ASTM D-2172 to extract the asphalt binder from FRAC samples. The amount of fiber remaining after extraction is measured by washing, sieving, manually removing the fiber, and recording total fiber mass.
Fiber reinforced asphalt concrete evaluated in this study meets several if not all of these categories. The material tests in this study indicated that the dynamic modulus of FRAC is improved over a control mixture especially at 100°F (34.8°C). Beam fatigue test results also showed substantial improvement as a result from the addition of fibers.
