Recent developments and applications of pavement analysis using nonlinear damage (PANDA) model
Additional Document Info
This paper presents an overview of the development and applications of the PANDA (Pavement Analysis using Nonlinear Damage Approach) model that has been under development at Texas A&M University for the past few years. In addition to the basics of the constitutive relationships used in PANDA, this paper presents examples of calibration and validation of the model using experimental laboratory data. The results demonstrate clearly the ability of the model to describe the mechanical behaviour of asphalt mixtures in terms of resistance to damage and permanent deformation. Finally, the capabilities of the model to simulate the mesoscale response of asphalt mixtures are presented and their implications in the design of asphalt mixtures are discussed. RILEM 2012.
