“…This research found a value of 64°C before and after performing the RTFO (Rolling Thin Film Oven). Research (35,36,(39)(40)(41)(42)(43) obtained values similar to the results observed in Table 2, both for physical and rheological characterization data. The multiple stress creep and recovery (MSCR) assay was performed at the maximum temperature of the PG (64°C).…”

Dark colors aggravate the absorption and accumulation of heat in urban centers in the layers of asphalt coating. These problems can be minimized by incorporating materials that increase the albedo on these pavements. The use of waste in the industry has been encouraged, and an alternative is iron ore tailing (IoT), whose material comes from processing iron ore. The circular economy encourages a change in waste disposal after project decommissioning, encouraging the transformation, reuse, and recycling of waste. Therefore, this research investigated the influence of percentages of IoT in the contents (7.5%, 10.0%, and 12.5%) as a substitute for fine natural aggregate on hot asphalt mixtures’ mechanical and thermal performance. The statistical variance test (ANOVA) was used to validate the obtained data. An economic analysis concerning the costs of production and recovery of asphalt mixtures was carried out using the Present Net Value. Asphalt mixtures with IoT were evaluated with regard to the environmental aspect using the circularity index. Among the asphalt mixtures analyzed, the one produced with 12.5% was the most viable. The results showed a gain in mechanical performance concerning tensile strength, resilient modulus, fatigue, and permanent deformation of this mixture, as well as a reduction in production costs per kilometer of highway. The use of 12.5% provided a greater circularity and a reduction of the surface temperature of the pavement by 2.9°C. IoT is viable in constructing highways close to places that produce iron ore.

“…Petroleum asphalt, known for its high viscosity, is widely employed as a binder in road constructions due to its economic advantages, noise reduction capabilities, facilitation of a comfortable driving experience, and ease of use in construction compared with cement road surfaces [1,2]. However, as the global economy rapidly evolves, conventional asphalt pavements are continually plagued by issues such as cracking, ruts, potholes, and surface deformation, rendering them inadequate for meeting the demands of today's road traffic loads and the harsh and ever-changing natural environment [3][4][5].…”

This study comprehensively examines the influence of phenol-formaldehyde resin (PF) on the performance of base asphalt and its mixtures for road applications, emphasizing its innovative use in enhancing pavement quality. Optimal PF content was determined through the evaluation of standard indicators and rotational viscosity. In-depth analyses of PF-modified asphalt’s high- and low-temperature rheological properties and viscoelastic behavior were conducted using dynamic shear rheometers and bending beam rheometers. Aging resistance was assessed through short-term aging and performance grade (PG) grading. Moreover, Marshall and water stability tests were performed on PF-modified asphalt mixtures. Findings indicate that the uniform dispersion of PF particles effectively inhibits asphalt flow at high temperatures, impedes oxygen penetration, and delays the transition from elasticity to viscosity. These unique properties enhance the high-temperature stability, rutting resistance, and aging resistance of PF-modified asphalt. However, under extremely low temperatures, PF’s brittleness may impact asphalt flexibility. Nonetheless, the structural advantages of PF-modified asphalt, such as improved mixture density and stability, contribute to enhanced high-temperature performance, water stability, adhesion, and freeze–thaw cycle stability. This research demonstrates the feasibility and effectiveness of using PF to enhance the overall performance of base asphalt and asphalt mixtures for road construction.

“…A significant number of researchers have studied bitumen alteration in order to achieve improved durability and high stability and strength. In the past, countless initiatives Polymers 2022, 14, 2493 2 of 27 have been explored, and scholars have effectively utilized numerous waste materials e.g., crumb rubber [3,4], nylon and polymer waste [5][6][7], polyethylene [8,9], polypropelene [10], recycled PET [11,12], polystyrene [13], and ordinary plastic bottles [14][15][16], etc. The positive enhancement of all these leading bituminous qualities that are crucial for road construction is recognized as a primary goal of all these investigations [17,18].…”

Eco-friendly waste utilization helps in the development of sustainable infrastructures. Recently, researchers have focused on the production of road infrastructures using the circular economy concept of human safety. The objective of this study is to investigate and explore the utilization of optimum polymer waste content for the development of polymer-modified asphalt mixtures using response surface methodology (RSM). RSM based on Box–Behnken design (BBD) was employed to optimize experimental design and included three factors: X1, polymer type; X2, polymer contents; and X3, testing day. The optimized responses determined by the RSM were as follows: MS of 42.98 kN, MF of 5.08 mm, and MQ of 8.66 kN/mm, indicating a favorable and consistent precision in comparison with experimental values. Moreover, the Marshall characteristics of samples prepared with PE were quite improved compared to PET. In conclusion, the incorporation of such polymer wastes in road construction is a sustainable and cost-effective way of improving their engineering properties. This study will help in the development of sustainable road infrastructures supporting human safety and environmentally friendly practices.
