Waste materials in asphalt mixtures have garnered significant interest due to environmental concerns and the necessity for sustainable infrastructure. This study evaluated the performance of a waste material-based hybrid asphalt mixture, including palm oil fuel ash (POFA), garnet waste, and sawdust. Numerous physical tests were conducted to examine the hybrid asphalt mixture characteristics, such as penetration, softening point, and viscosity assessments. A Marshall stability and Dynamic Shear Rheometer (DSR) was also performed to assess the stability and rheological characteristic of the mixture. Consequently, the hybrid asphalt mixture demonstrated favourable outcomes in improving the hot mix asphalt characteristics. These findings suggested that the hybrid contents (0% as control, 3%, 6%, and 9%) produced a significant performance impact on the hybrid asphalt mixture. The 6% hybrid asphalt mixture yielded the highest stability, delivering a Marshall stability value of 22.33 kN and suitable ageing resistance of asphalt samples due to the high sensitivity of the binder to the test temperature. Furthermore, the scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies reported strong adhesion and interaction between the particles in the 6% hybrid asphalt mixture. This study effectively demonstrated that the waste materials (POFA, garnet waste, and sawdust) in the hybrid asphalt mixtures developed enhanced physical and mechanical characteristics. The results also indicated that the hybrid asphalt mixtures exhibited potential durability and performance in improving the longevity and efficacy of hot mix asphalts. Therefore, this study provided evidence of effective and sustainable construction practices in asphalt pavements. Further research on waste components in asphalt mixtures should also be investigated to enhance their overall efficacy.

“…This material is utilised as a substitute for a portion of the fine aggregate in asphalt pavement [27]. A study by [19] replicated similar findings using garnet waste for bitumen modification. The study described the enhanced stability of the mixture based on the Marshall test following several load axial tests.…”

“…The ground POFA generally displays irregular, thinner, and crushed particles arranged in clusters of spherical particles with minimal air space between them [47]. A study by Usman et al provided the micrograph results of the garnet waste samples at a 25% level using SEM, which reduced particle accumulation [48]. The study provided the micrograph results of the garnet waste samples at a 25% level, which reduced particle accumulation.…”

Approximately 3 billion metric tonnes of garbage involving industrial and agricultural waste is expected to be generated by 2030, posing a significant environmental hazard. Notably, recycling or reusing asphalt modification components (palm oil fuel ash (POFA), garnet waste, and sawdust) in pavement construction encounter ongoing challenges. This study comprehensively assessed the chemical characteristics and microstructure analysis of individual wastes and various hybrid asphalt binder mixtures incorporated with these components. The mixture consisted of asphalt grade 60/70 blended with varying amounts (0%, 3%, 6%, and 9%) of POFA, garnet waste, and sawdust. Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), and X-ray diffraction (XRD) analyses were also employed to examine the chemical compositions of the raw waste materials. Meanwhile, the microstructure properties of various hybrid asphalt binder mixtures were analysed utilising Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Consequently, this study presented that the correlation between the 6% POFA, 6% garnet waste, and 6% sawdust substantially impacted the chemical composition and morphology of the mixture. The findings of this study demonstrated that including POFA, garnet waste, and sawdust in a hybrid asphalt binder mixture could enhance performance and engineering properties.

“…This relates to issues with inappropriate performance and the delay before full strength is reached following paving and the potential for rainfall to harm early life (Oruc et al, 2007). Emulsified asphalt cold mix (EACM), which is CMA using bitumen emulsion as a binder, has a relatively low initial strength and is regarded as an evolutionary material, particularly in its early life when initial strength is relatively low and grows up gradually (Usman et al, 2021;Dulaimi et al, 2022;Shen et al, 2022).…”

Application of paper sludge ash and incinerated sewage ash in emulsified asphalt cold mixtures

Certain disadvantages could have appeared while using hot mix asphalt (HMA), such as the release of unhealthy gases into the environment (environmental issues), difficulty in sustaining the temperature over long distances (logistical issues), and consuming a sufficient amount of energy while preparing and laying down (practical and economic issues). To overcome the aforementioned issues, this study aimed to develop rapid-curing emulsified asphalt cold mixes (EACM) comprising a cementitious filler made from industrial by-product materials. Paper sludge ash (PSA) is used as an active filler for application in the EACM rather than conventional mineral filler. Additionally, to maximize the effect of PSA’s hydraulic activity, incinerated sewage ash (ISA) is utilized as an activator at a concentration of 0%–4% by mass of the aggregates. The results demonstrate that the use of waste PSA significantly improves the indirect tensile stiffness modulus (ITSM) by around 10 times more after 2 days than the traditional emulsified asphalt cold mixes. In addition, the improvement in ITSM was around 30% and 65% for 6%PSA+1%ISA and 6%PSA+4%ISA mixes, respectively. Furthermore, the rutting for the 6%PSA+1%ISA and 6%PSA+4%ISA mixes decreased to around 19% and 11% in comparison to the traditional 131-pen HMA. The formation of hydration products and rapid demulsification of asphalt emulsion, which results in binding within the mixtures, are responsible for the increased ITSM and rutting resistance. As a result, environmental issues are minimized, and energy preservation may be maintained.
