Investigation of Cracking Potential of Modified Asphalt Mixes Composed of Synthetic Fibers by Performing 4-point Bending Test
Fatigue cracking on Hot Mix Asphalt (HMA) affects the serviceability and quality on roads. Past studies have shown that synthetic fibers have the potential to enhance the fatigue properties of asphalt concrete, which motivated the present work to evaluate the effectiveness of adding polymer fibers to hot mix asphalt, to increase the resistance of HMA to fatigue cracking at intermediate temperatures. For this purpose, three different types of polymer fibers, including aramids, polyethylene terephthalate (PET) and polyacrylonitrile (PAN), in different sizes and at different concentrations, were added to conventional hot asphalt mixes. The impact of different parameters such as strain level and fiber content were evaluated on reinforced and unreinforced mixes by the four-point beam fatigue test. Finally, the output of the bending fatigue test was compared with the results of the IDEAL CT test to evaluate the correlation between these tests.
