Dynamic modulus characterizes the viscoelastic behavior of asphalt materials and is the most important input parameter for design and rehabilitation of flexible pavements using Mechanistic–Empirical Pavement Design Guide (MEPDG). Laboratory determination of dynamic modulus is very expensive and time consuming. To overcome this challenge, several predictive models were developed to determine dyn...

This paper presents a non-linear modeling framework that supports model development \in between" empirical and mechanistic modeling. A model is composed of a number of local models valid in diierent operating regimes. The local models are combined by smooth interpolation into a complete global model. It is illustrated how diierent kinds of empirical and mechanistic knowledge and models can be c...

Variations in tree-ring structure are simulated with (1) an empirical model using monthly climatic data as statistical predictors and (2) a mechanisbc model using daily climatic data as growth limiting conditions. The empirical model calibrates standardized ring-width and density chronologies of tree-rings with monthly temperature, precipitation or Palmer Drought Severity Index. The empirical m...
