This study reports on the laboratory performance, field performance and cost analysis of fiber-reinforced asphalt concrete (FR-AC) pavement using AC60/70 and polymer modified asphalt (PMA) as binders. The performance testing included indirect tensile resilient modulus, indirect tensile strength modulus, indirect tensile fatigue life, dynamic creep and wheel-tracker tests. Field trials of AC60/70 and PMA mixtures, were undertaken with and without fibers and the International Roughness Index, texture depth, and rutting of the mixtures were measured over time.

- Fly Ash (FA) serves as an eco-friendly stabilizer to improve the properties of crushed brick (CB) and reclaimed asphalt pavement (RAP) for use in pavements.
- Experiments were conducted to measure the Unconfined Compressive Strength (UCS) and resilient modulus (M) of these materials at room temperature and 40°C, with findings indicating that FA effectively enhances the strength and durability of recycled aggregates.
- The study concluded that the optimal amount of FA for stabilization was 15%, leading to the best strength results, particularly when cured at higher temperatures.
