摘要

As the volume of solid waste generated by human activities continues to rise, waste management and resource utilization are encountering substantial difficulties. This review explores the progress in the utilization of solid waste in asphalt mixture from 2000 to 2024. The pretreatment methods, technical specifications for road engineering applications, and testing techniques are analyzed. The impacts of solid waste on the performance of asphalt and asphalt mixtures are also investigated. Solid waste can be used either as aggregates or asphalt modifiers. The dosage of solid waste in modified asphalt, typically not exceeding 6%, can be determined by dynamic shear rheometer (DSR) test and Bending Beam Rheometer (BBR) test. The dosage of solid waste as aggregate in asphalt mixtures, usually ranging from 30% to 86% by the weight of aggregate, can be determined by tests such as the Marshall test, indirect tensile test (IDT), and rutting test. Regarding high-temperature performance, the influence of solid waste is type-dependent. Most materials enhance rutting resistance. Rice husk ash (RHA) raises Marshall stability by 65.4 %, waste tire rubber (WTR) increases dynamic stability by 88.5 %, and waste glass (WG) raises it by 45 %. In contrast, SSA reduces stability by 26.7 %. At low temperatures, the incorporation of short wheat straw flakes (SWSF) increases the flexural stiffness modulus by more than 40 %, whereas waste nylon thread (WNT) enhances the ultimate tensile strain by 25 %. Conversely, recycled fine aggregate powder (RFAP) adversely affects the stiffness modulus. Both straw composite fiber (SCF) and Recycled brick powder (RBP) significantly improve fatigue resistance, whereas ceramic waste aggregate (CWAs) yield no appreciable benefit. Recycled concrete aggregate (RCA) elevates the tensile strength ratio (TSR) by 30 %, and rubber particles (RP) improves moisture stability. Nevertheless, municipal solid waste incineration ash (MSWIs) and SWSF compromise this property. electric arc furnace steel dust (EAF dust) and RHA effectively mitigate the degree of stiffening caused by oxidative aging. The interactions between solid waste and asphalt include both physical and chemical mechanisms, which significantly influence the performance of asphalt mixture.
