Current prediction models are often regression-based and lack accuracy, necessitating the adoption of mechanistic models like the Viscoelastic-Continuum Damage (VECD) models. The VECD models often rely on Schapery's work potential theory and elastic-viscoelastic correspondence principles, using pseudo-strain to separate viscoelasticity from damage mechanics. However, this decoupling imposes constraints on how viscoelastic properties can evolve. This study presents a new VECD model that fully couples the viscoelasticity of the material with its damage characteristics. It was developed within a Helmholtz-potential-based thermodynamic framework, ensuring consistency with the laws of thermodynamics. The model could describe the evolution of both the apparent storage modulus and loss modulus during fatigue tests over a wide range of strain levels. It captures the three-stage fatigue behavior of asphalt concrete, allows for unconstrained variations in the apparent phase angle, and provides a clear point of failure. Moreover, it can capture the variation of fatigue life with the applied strain level in a manner similar to the Asphalt Institute fatigue life model. asphalt concrete fatigue viscoelasticity damage model Full Text Cite Share Download PDF Status: Published Journal Publication published 25 Feb, 2025 Read the published version in Materials and Structures → Version 1 posted Editorial decision: Accept 04 Feb, 2025 Reviewers agreed at journal 20 Dec, 2024 Reviewers invited by journal 18 Dec, 2024 Editor invited by journal 17 Dec, 2024 Editor assigned by journal 17 Dec, 2024 First submitted to journal 16 Dec, 2024 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
