Abstract: Long-life pavement has been introduced to address the urgent need for durable and reliable transportation infrastructure. This review overviews the development of aggregates for long-life pavements and summarizes future research directions. The review indicates that natural aggregates, being non-renewable resources, are steadily declining in availability and may need to meet future demands. Construction solid waste aggregates are rapidly developing, with fine separation of reclaimed asphalt pavement (RAP) and reinforcement of cement-based recycled aggregates serving as key strategies to enhance their application. Industry solid waste aggregates possess properties suitable for long-life pavements and offer additional functionalities such as cooling, conductivity, and reflectivity, demonstrating significant development potential. While artificial aggregates exhibit superior performance, their large-scale application requires consideration of economic and environmental impacts. Current aggregate evaluation methods need to address the needs of long-life pavements. Aggregate performance requirements should be graded based on mechanical stress and temperature distribution, with corresponding evaluation methods and indices developed. Evaluating the mechanical properties of aggregates should align more closely with actual stress states. Tests such as triaxial, repeated load, and wheel abrasion polishing are better suited for assessing the strength and durability of long-life pavement aggregates. Similarly, evaluating aggregates' physicochemical properties should be based on studies correlating these properties with road performance, with proposed evaluation criteria. Morphological characteristics of aggregates significantly influence asphalt mixture performance, and efficient evaluation of their profile, angularity, and texture will be a key focus of future research.
