A continuum damage model for asphalt cement and asphalt mastic fatigue

摘要: Abstract An analytical model is developed for the mechanical degradation of asphalt cement and mastic under repeated loading. The derived by applying strain decomposition principle to consider linear viscoelastic, nonlinear damage mechanisms. experimental processes isolate behaviors functions used each are described. It found that Schapery type approach capable modeling fatigue process these materials once appropriate consideration taken their viscoelastic responses. Fatigue in mastics also occur due physical occurring cement.
