Seasonal Performance Prediction Comparison of Unreinforced and Fiber-Reinforced Asphalt Mixtures for Airfield Pavements

Fiber-reinforced asphalt concrete (FRAC) improves the fatigue and rutting performance of highways. However, the predicted performance of FRAC for airport pavements in various climates is still unknown. Four fiber types (carbon, glass, basalt, and polyolefin/aramid) and two binder grades (PG76-22 and PG58-28) were used for two climates. Typically, airport pavement design models (FAARFIELD) do not account for temperature variations during pavement service life. The laboratory-measured dynamic modulus values for each sub-season were incorporated into PCASE software to evaluate the selected thickness. The damage was evaluated using FAARFIELD rutting and fatigue models. Furthermore, Pavement Classification Rating (PCR) was determined for control and FRAC by using FAARFIELD. The results showed that PFA fibers are equally good in rutting and fatigue life for both regions and binders. However, carbon fibers showed lower damage for PG76-22. Finally, the PCR results showed higher strengths for the pavements in cold climates than in hot climates.
