文摘
- •
An energy-based model for damage and fracture in viscoelastic asphalt mixtures.
- •
Based on continuum damage mechanics and thermodynamics of irreversible processes.
- •
Energy-based criteria are introduced for micro-crack initiation and accumulation.
- •
A temperature-dependent critical micro-crack threshold is established.
- •
Model describes damage for both conventional and non-conventional asphalt mixtures.
