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.

“…[14]. Much research on the fatigue and rutting problem of asphalt pavement design has been conducted [15][16][17][18][19][20][21]. At present, the gradation design methods are conducted based on practical experience and a large number of experiments, and they do not effectively solve in advance the rutting and fatigue performance of asphalt mixtures.…”

To solve the durability of flexible base asphalt pavement, especially its anti-rutting problem, a design method on durable asphalt pavement of flexible base on anti-rutting performance was put forward in the paper, based on many experiments and calculations. Firstly, a method that asphalt could be selected according to penetration and the anti-rutting factor of its base asphalt was found, which solved the problem of the asphalt selection of the flexible base asphalt mixture design. Meanwhile, a method of skeleton-density structure gradation design was proposed based on the fractal void ratio of coarse aggregate, fractal volume of fine aggregate in coarse aggregate, penetration, fractal dimension of gradation particle size, and rutting tests, which effectively solved in advance the rutting and fatigue performance of flexible base asphalt mixtures. Then, on the basis of the fatigue damage, a calculation method of fatigue life was suggested, which solved the problem that the fatigue damage of asphalt mixtures rarely considered the combined effects of creep damage and fatigue damage. In addition, a calculation method of rutting was formulated based on vehicle dynamic load and ANSYS 16.0 software. Lastly, the feasibility of the design method on durable asphalt pavement of flexible base on anti-rutting performance was verified combining with the real engineering of a supporting project and several numerical calculations and tests.

“…Various factors influence asphalt pavement durability on roads because the construction processes, quality of materials, design aspects, weather conditions, as well as operating conditions directly contribute to asphalt pavement durability. Most of the studies where factors that impact asphalt pavements durability are identified mainly focus on (1) traffic effects and vehicular loads, (2) characteristics and properties of the materials that make up the structure of the pavements, and (3) weather and road operation effects [4]. Under the coupled action of traffic and environmental effects, asphalt binders undergo significant physical changes such as aging, healing, and premature failure due to their sensitivity to temperature and loading rate, resulting in the early deterioration of asphalt pavement performance [5][6][7].…”

Asphalt binder is a temperature-sensitive material with a performance that is greatly affected by changing climates. Improper selection of asphalt will cause a lot of damage and affect the durability of the road. The establishment of asphalt pavement performance zoning in Xinjiang, a vast area with great temperature differences, will provide a reference for the selection of asphalt suitability, the refinement of pavement design, and the sustainable development of road engineering. In this study, 11 years of temperature data in the Xinjiang region have been collected and analyzed, and 98% reliability of pavement design temperature has been used to draw a performance grading map of asphalt pavement in the Xinjiang region based on the ArcGIS platform. Finally, the Xinjiang region is divided into nine performance zones. At the same time, the performance grades (PG) of five kinds of asphalt binders in Karamay are explored. The result shows that there is little difference in continuous PG span between different matrix asphalt binders; the lower the penetration grade, the better the high-temperature performance, and the worse the low-temperature performance. After adding the SBS modifier, the continuous PG span can be about 20 °C higher than the matrix asphalt. The indoor test of asphalt mixture also shows that SBS-modified asphalt has better durability. All these provide the basis for a reasonable selection of asphalt binders in different areas of Xinjiang.
