“…On fatigue, performance is 52% [ 20 ]. The study found that the type of filler and the filler-to-asphalt mass ratio significantly affect the properties of asphalt mastic and, therefore, the viscoelasticity and rheology of asphalt mixtures [ 21 , 22 , 23 ]. One study by Lagos-Varas showed that adding filler increases the stiffness of asphalt and reduces permanent deformation at high temperatures [ 24 ].…”

Glass fiber reinforced polymer (GFRP) is the main composite material used in wind turbine blades. In recent years, zero-carbon energy sources such as wind power have been widely used to reduce carbon emissions, resulting in a large amount of waste GFRP, and causing serious environmental problems. To explore efficient ways to recycle waste GFRP, this study explores the impact of adding GFRP powder (nominal maximum particle size ≤ 0.075 mm) on the high and low temperature properties of asphalt mastic. Samples of GFRP asphalt mastics were prepared with filler-asphalt mass ratios of 0.01:1, 0.1:1, 0.8:1, and 1:1, as well as two control samples of limestone filler asphalt mastics with filler-asphalt mass ratios of 0.8:1 and 1:1. The study analyzed the effect of GFRP on the asphalt mastic’s performance using temperature sweep, MSCR, and BBR tests. Results showed that the presence of GFRP improved the high-temperature resistance and recovery of asphalt mastic but led to decreased low-temperature crack resistance. The results suggest that GFRP has the potential to be used as a filler in asphalt mastic, with a recommended filler-asphalt mass ratio range of less than 0.8:1 for optimal low-temperature performance. However, further research is necessary to determine the optimal content of GFRP in asphalt mastic and to study its impact on other road performance metrics.

“…Permanent deformation that is revealed in wheel paths, bus stops, and area with steep slopes significantly affects the safety, roughness, and ease of transport [1][2][3]. Accordingly, numerous research studies have been performed aimed at determining a convenient way of improving resistance against permanent deformation, such as Binder modification [4][5][6][7], incorporating high modulus and artificial aggregates [8,9], and the use of recycled materials [10][11][12][13][14][15]. Besides, the resistance of different asphalt mixtures against permanent deformation would be varied concerning what was adopted in the definition of the loading regime.…”

Flow number (FN) reflects the resistance of asphalt mixtures against rutting failure by assessing the results of repeated loading permit deformation (RLPD) testing, affecting the different loading regimes. Accordingly, this work was conducted to investigate the impact of loading variables, i.e., loading duration, rest ratio, and loading pulse waveform, in addition to the testing temperature on the permanent deformation accumulation. Square and Haversine waveforms were chosen as the loading waves. Besides, three levels of loading duration (100, 500, and 1000 ms), two levels of rest ratios (1 and 3), and two testing temperatures (40 and 55 °C) were considered in the definition of loading regimes. The Francken model was fitted over the experimental data aim to determine the FN points. Weibull distribution analysis was also applied to distinguish between the different levels of testing variables. The results indicated that testing temperature was the most significant variable in permanent deformation accumulation, and loading duration was the most effective in defining loading regimes. Increasing loading duration and rest ratios resulted in an increased rate of permanent deformation accumulation and lower FN values. The specimens exposed to the square waveform were reached the FN sooner than those exposed to haversine.
