Selection and evaluation of models for prediction of permanent deformations of unbound granular materials in road pavements Draft report (original) (raw)

The report reviews existing models for predicting permanent deformations of unbound granular materials (UGMs) used in road pavements, particularly for the SAMARIS project. It discusses the mechanical behavior of UGMs, identifies the challenges of current empirical design methods, and emphasizes the need for improved testing and modeling approaches, particularly as new materials like recycled aggregates are increasingly used. The findings underscore the necessity of developing accurate predictive models and evaluation methods to facilitate effective pavement design.
