Abstract
This article offers a comprehensive assessment of the literature on the mechanical modeling of the rheological characteristics of asphalt concrete. Improving knowledge of existing models and their ability to predict material behavior is the aim. Because asphalt concrete is complex, temperature-sensitive, and time-dependent, several rheological models have been developed to faithfully capture its viscoelastic properties. This overview highlights the theoretical underpinnings, underlying presumptions, and real-world applications of a number of models, including fractional-order models, linear and nonlinear viscoelastic models, and viscoplastic models. We assess each model's advantages and disadvantages based on how well it can simulate real-world loading situations and temperature variations in pavement engineering. This study identifies areas that need improvement and offers insights into the efficacy of these models through a methodical investigation. The assessment concludes with recommendations for future lines of inquiry, emphasizing the value of thorough models that take into account the environmental and mechanical elements influencing asphalt concrete performance.
