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.

In recent years, the integration of Nanoclay (NC) into concrete has garnered significant global attention due to its potential added benefits and importance in the construction industry. However, the existing literature lacks sufficient experimental validation and empirical analysis pertaining to several unexplored key properties, such as thermal resistance, conductivity, diffusivity, and fire resistance. This study aims to address these knowledge gaps and contribute to the current body of literature by providing a comprehensive review of the advantageous effects of NC incorporation on the aforementioned properties of concrete. A thorough examination of available data was conducted, focusing on the mechanical and thermal characteristics of concrete after the inclusion of NC in the mix design. The findings of this critical review indicate that the incorporation of NC into concrete can reduce building energy consumption and enhance thermal insulation properties. Moreover, the integration of NC in concrete was found to improve various thermal features, including thermal stability, fire resistance, thermal performance, thermal behavior, resistance to thermal cracking, and resistance to thermal degradation. In addition, the inclusion of NC in concrete was observed to decrease thermal conductivity, thereby facilitating effective thermal insulation and resulting in lower energy consumption during heating and cooling periods. Simultaneously, the integration of NC was found to bolster the compressive, flexural, and tensile mechanical properties of concrete. Furthermore, the incorporation of NC into concrete materials has the potential to mitigate negative environmental impacts, such as pollution and poor air quality. This comprehensive review provides valuable insights into the benefits of NC integration in concrete, paving the way for further research and innovative applications in the construction industry.

The use of recycled polyester fiber (Re-PET) partially addresses the scarcity of non-renewable polyester (PET), but its thermal resistance in asphalt mixtures is relatively low. To enhance the reutilization and thermal resistance of Re-PET, it was modified through in situ growth grafting with tetrahedral nanoSiO2. A novel nanoSiO2 hybrid material (SiO2/Re-PET) was successfully prepared, and the effects of the surface modification on the morphology and thermal resistance of the Re-PET were investigated with the examination of its mechanism of modification. The results demonstrated an increase in the surface roughness and specific surface area of SiO2/Re-PET, as well as a higher melting point and structural stability compared to Re-PET. Subsequently, Re-PET and SiO2/Re-PET asphalt mastics under a filler–asphalt ratio of 1.0 were prepared, and their classical and rheological properties were investigated and compared. The results indicated an increase in the softening point and shear strength of SiO2/Re-PET asphalt mastic, as well as a significant improvement in its high-temperature performance. Furthermore, subsequent pavement performance tests revealed a significant improvement in the performance of SiO2/Re-PET asphalt mixtures compared to Re-PET asphalt mixtures. Consequently, the findings of this research promote the recycling of Re-PET, ultimately advocating for the sustainability of pavement construction.
