“…Recently, there have been several successful attempts to improve the laboratory test using a temperature gradient controlling system or designing appropriate dimensions of specimen and loading plate (Huang and Zhang, 2010;Guan et al, 2011). An advanced repeated load permanent deformation (ARLPD) test protocol has been developed to simulate field conditions in the laboratory Gao et al, 2014;Gu et al, 2015). It was observed that the ARLPD test results matched well with the field data since it could largely simulate the stress state, lateral confinement, and temperature gradient in actual pavements (Li et al, 2015).…”

An advanced repeated load permanent deformation (ARLPD) test that can simulate the lateral confinement and temperature gradient in actual pavements was employed in this study. The test was conducted based on field cores and laboratory-made specimens of several newly constructed hot mix asphalt (HMA) pavements, reclaimed asphalt pavements (RAP), and asphalt overlay pavements. The rutting resistance and distribution were evaluated using various rutting indicators. It is found that newly constructed HMA layers using the SBS modified binder show a great improvement in the rutting resistance. Overlay and hot in-place recycling (HIR) pavements exhibit similar anti-rutting performance. The cold in-place recycling (CIR) mixture could be used in the bottom asphalt layer for highway maintenance. For overlay and HIR pavements, the new top asphalt layer contributes approximately half of the total rut depth. The rutting distribution is relatively uniform when SBS modified binder is used in the middle asphalt layer.

“…The importance of encouraging individual innovation for businesses is essential to staying competitive and prospering. As such, companies are always looking for ways to encourage their staff to be creative and come up with original ideas (Gu et al, 2015). Therefore, many studies have investigated the dynamics of employee creativity, in particular, to identify the factors that promote or limit innovation in their organizations (Chaubey & Sahoo, 2022;Zhou & Shalley, 2008).…”

This study aimed to explore the relationship between ethical leadership and employees’ innovative behavior. The study relied on the analytical-descriptive approach through a review of the theoretical subjects related to previous studies and the analytical-practical aspect through preparing a questionnaire and distributing it to the targeted population of the study, while relying on the SPSS and Amos programs to test the hypotheses of the study and achieve its objectives. The results showed that there was an impact for ethical leadership on the employees’ innovative behavior and the organizational commitment partially mediates the relationship between ethical leadership and the employee's innovative behavior.

“…Asphalt mixture is the most important engineering material for high-grade pavement, which faces the challenge of various and frequently occurring early diseases, e.g., rutting, cracks, and water damage, seriously limiting the service life of the pavement structure (Gu et al, 2015;Wang et al, 2016). To solve these problems, the high-and low-temperature performance of asphalt mixture is improved by adding polymer modifiers to the binder, such as SBS, SBR, and EVA (Lu et al, 2003;Yildirim, 2007;Sengoz and Isikyakar, 2008) and adding various reinforcements to asphalt mixture, including basalt fiber, glass fiber, waste tires, and waste glass powder materials (Cao, 2007;Abtahi et al, 2010).…”

Utilization of waste wind turbine blades in performance improvement of asphalt mixture

et al. 2023

Redundant wind turbine blades (WTBs) retired from wind power facilities produce substantial waste annually and induce challenging environmental problems. As the most widely used materials for high-grade pavement construction, asphalt mixtures must have excellent high- and low-temperature performance, as well as water damage resistance, since pavement is subjected to complex loading, temperature, and humidity changes. This study proposed an asphalt mixture with the addition of two types of recycled WTB (rWTB): rWTB powders of granular sizes below 0.075 mm and rWTB fibers in the size range of 0.075–9.5 mm. First, the thermogravimetric analysis results indicated the accepted thermal stability of rWTB material for the requirement of compaction, paving, and service condition of asphalt mixtures. Second, the properties of the asphalt mixtures modified by using (i) rWTB powder (5 wt%, 10 wt%, and 15 wt% in fine filler), (ii) rWTB fiber (0.1 wt%, 0.2 wt% and 0.3 wt% in fine aggregate), and (iii) both rWTB powder and fiber were investigated by wheel tracking tests at 60°C, three-point bending tests at −10°C, and Marshall immersion tests. The experimental results showed that the rWTB asphalt mixtures could improve the overall road performance of asphalt mixtures, and that an optimal pavement performance could be obtained by the synergistic addition of rWTB powder and fiber. In addition, it was indicated that the improving mechanism of the rWTB material on the asphalt mixture was mainly attributed to its good compatibility with the asphalt binder, allowing the rWTB to strengthen asphalt mortar and improve the high- and low-temperature performance of the asphalt mixture.
