“…By optimizing the mixing and processing conditions, the researchers were able to achieve a more uniform and stable network structure within the CRMA, resulting in improved storage stability [26]. Gray-level cooccurrence matrix (GLCM) provides valuable insights into the microstructure and texture characteristics of the composite material, as well as its rheological behavior [27]. The utilization of palm oil waste as a sustainable alternative in asphalt mixtures can reduce environmental impacts and promote the circular economy by converting waste materials into valuable resources [28].…”

Highway infrastructures play an important part in local and international studies of emerging metropolitan cities because of their direct and indirect impact on urban expansion, environmental issues, and socioeconomic challenges.Transverse and longitudinal fractures, potholes, and subgrade deformation in flexible pavement result from the higher rate of vehicle addition on the roads to the space of road building. Due to an increase in the number of vehicles on the road, flexible pavements have developed cracks and deformations below the subgrade [1]. *Author for correspondence Different types of waste plastic bottles and optimizing the percentage of additive for improved performance of the asphalt [2].The effects of waste polymer modification on the performance and sustainability of asphalt mixtures. Their findings indicated improved resistance to fatigue cracking and reduced environmental impacts, particularly in terms of energy consumption and carbon emissions [3]. Incorporating disposable medical masks (DMM) enhanced the high and lowtemperature performance of the asphalt, leading to improved complex modulus, rotational viscosity, and tensile elongation.

“…Rapid economic development [1], human activity [2], and urbanization [3,4] generate billions of tons of solid waste in urban areas worldwide [5], and municipal solid waste incineration (MSWI) residues accompany this waste [6,7]. Given their size distribution and chemical composition [8], the geotechnical properties of MSWIRs can increase recycling potential in construction when used as light fillers and aggregates [9].…”

As a sustainable substitute for non-renewable mineral resources and solid waste landfilling, municipal solid waste incineration residues (MSWIRs) are useful in road pavements. This study investigates the thermal characteristics and temperature distribution of flexible pavements containing MSWIRs with hollow microsphere structures. First, the volumetric properties of asphalt mixtures containing MSWIR fillers were measured. The effects of MSWIRs on the mixture’s physical characteristics were investigated in terms of thermal conductivity, specific heat capacity, and thermal diffusivity. A three-dimensional finite element model incorporating surface thermal conditions was established and validated to analyze the internal temperature distribution and heat transfer behavior within the asphalt. Finally, the high-temperature conditions of summer were simulated in an indoor irradiation test to evaluate the risk of heat islands in urban areas. The results showed that the mixture containing MSWIRs exhibited a higher specific heat capacity (from 0.8385 to 0.9554 J/(kg·K)) and lower thermal conductivity (from 1.4356 to 1.1362 W/(m·K)) than the reference mixture with limestone filler. Therefore, it contributed to a lower heat flux distribution within the pavement. However, the increase in asphalt surface temperature caused by MSWIRs may exacerbate the urban heat island effect in the summer, which should be considered before using road materials containing MSWIRs.

This research takes on a scientific problem originating from the pervasive deterioration observed in the pavements of Bus Rapid Transit (BRT) systems, which presents formidable challenges to their durability and imposes significant financial burdens on BRT organizations. While wear and tear on BRT pavements is a widely recognized concern, there exists a pronounced deficiency in sustainable solutions to address this issue comprehensively. This study endeavored to bridge this scientific gap by exploring the option of incorporating waste plastic aggregate (WPA) and recycled asphalt pavement (RAP) into the pavement material. The series of comprehensive investigations commenced with an assessment of modified binders. We identified a 25% extracted RAP binder as the most suitable candidate. Our research next determined that a 4% WPA content offers optimal results when used as an aggregate replacement in a stone-modified asphalt concrete mix, which is further refined with a 13 mm nominal maximum aggregate size (NMAS) gradation, resulting in superior performance. Under double-load conditions of the Hamburg Wheel Tracking test, rutting in the 10 mm NMAS mixture rapidly increased to 9 mm after 12,400 HWT cycles, while the 13 mm NMAS mixture showed a more gradual ascent to the same critical rutting level after 20,000 HWT cycles (a 61% increase). Real-world application at a designated BRT station area in Seoul reinforced the findings, revealing that the use of 13 mm NMAS with 4% WPA and RAP significantly improved performance, reducing rutting to 75 µm and enhancing pavement resilience. This configuration increased Road Bearing Capacity (RBC) to 5400 MPa at the center zone, showcasing superior load-bearing capability. Conversely, the 10 mm NMAS mixture without RAP and WPA experienced severe rutting (220 µm) and a 76% reduction in RBC to 1300 MPa, indicating diminished pavement durability. In general, this research highlights the need for innovative solutions to address BRT pavement maintenance challenges and offers a novel, environmentally friendly, and high-performance alternative to traditional methods.
