“…On the other hand, Fayissa et al, (2020) reported that as the sawdust content rose, the penetration value reduced, the softening point temperature rose, and the viscosity increased. The results for penetration, softening point, as well as viscosity presented that 15% was the proper content for the materials made from researched agricultural waste/by-product materials (Nassef et al, 2021). Softening point tests have been utilized to analyze the temperature susceptibility with regard to sawdust modi ed asphalt binders, with results indicating an increase in the penetration value, indicating softer consistency (Dominic et al, 2022).…”

“…Additionally, modi ed asphalt mixtures exhibit enhanced bulk density, which is crucial for ensuring the durability and longevity of pavements (Dominic et al, 2022). The optimal content of each by-product material in the modi ed asphalt mixtures was determined to be 15% based on the Marshall method (Nassef et al, 2021).

Recently, the volume and growth of industrial as well as agricultural waste have caused environmental pollution. However, this issue can be mitigated through recycling and reutilization of such waste products. Therefore, this paper evaluated the potential of Palm Oil Fuel Ash (POFA), garnet waste, and sawdust as sustainable modified asphalt binders and mixtures as a substitute strategy to encourage waste recycling in road pavement construction. POFA, garnet waste, and sawdust were blended with asphalt grade 60/70 with varied amounts of 0% (control), 3%, 6%, and 9%. Moreover, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Fluorescence (XRF), as well as X-Ray Diffraction (XRD) were utilized to analyze the microstructures of raw waste materials. The physical characteristics with regard to the modified asphalt binder were determined by employing softening point and penetration tests. Consequently, the modified asphalt mixture was assessed using the Marshall stability test. Specifically, adding 6% POFA, 3% garnet waste, and 3% sawdust performs best in stability as a modified asphalt mixture. The correlation of stability, flow, bulk density, and stiffness for POFA, garnet waste, and sawdust modified asphalt mixture was significant, with a strong Coefficient of Determination (R2) for all Marshall stability parameters. According to this study’s results, the correlation of POFA, garnet waste, and sawdust content may improve the performance and engineering characteristics with respect to modified asphalt binder and mixture.

The addition of palm oil fuel ash (POFA), garnet waste, and sawdust as a modified asphalt binder and mixture for paving materials show that recycling materials from industrial and agricultural waste have been implemented with environmental concern, increasing the proper handling of this waste product. The use of POFA, garnet waste, and sawdust as a modifier to improve the properties of binder and mixture is critically evaluated in this study. The review focuses on the evaluation of POFA, garnet waste, and sawdust in asphalt binder and mixture modification. In essence, the combination of POFA, garnet waste, and sawdust offer a promising waste materials potential to enhance the rheological and mechanical performance of the modified binder and mixture. The use of this modification in the binder and mixture is expected to improve performance and be on par with the traditional asphalt binder and mixture.

Introduction: The stability and tensile strength of asphalt mixtures play a crucial role in pavement durability, primarily due to the challenges associated with cracking. This study investigates the utilization of a hybrid asphalt mixture comprising hybrid materials: Palm Oil Fuel Ash (POFA), garnet waste and sawdust to enhance the modified asphalt performance. Aims: The objective is to examine the hybrid materials’ influence towards the mechanical properties of the hybrid asphalt mixture, specifically focusing on the Indirect Tensile Strength (ITS) as well as the Marshall stability test. Methods: To achieve this, hybrid materials were finely ground and sieved to 25µm before being incorporated into the mixture. The Marshall mix design procedure was conducted, utilizing hybrid binders at concentrations of 0% (control), 3% 6%, and 9%. The effects of the hybrid asphalt mixture on stability, flow, stiffness, and ITS were assessed at the optimal binder content. Results: The findings indicate that the hybrid asphalt mixture reveals enhanced Marshall stability, stiffness, flow, and ITS values compared to conventional asphalt mixtures. Notably, hybrid asphalt mixtures with 6% binder concentration demonstrate the most significant enhancement in terms of Marshall stability and ITS. Conclusion: This correlation suggests that the incorporation of POFA, garnet waste, and sawdust as hybrid materials in the hybrid asphalt mixture possesses a positive effect on the overall mechanical properties of the pavement. Highlights: • POFA, garnet waste, and sawdust increased the stability of the hybrid asphalt mixture. • POFA, garnet waste, and sawdust increased the tensile strength of the hybrid asphalt mixture. • Hybrid asphalt mixture performs positively towards flow and stiffness.
