ABSTRACT

This paper reports the details of a new layered elastic nonlinear cross anisotropic model that can consider the confinement effects of geogrids within pavements. The algorithm, herein called MatLEACANGG, was verified against well-known programs such as ELLEA2 (Layered Elastic-Cross Anisotropic model) and MichPave (Nonlinear Finite Element Model). Influence of the Geogrid on the vertical microstrain of unbound layers was illustrated via runs on four different structures (with and without Geogrid).
