Abstract: Pavement foundation geomaterials, i.e., fine-grained subgrade soils and unbound aggregates used in untreated base/subbase layers, exhibit nonlinear behavior under repeated wheel loads. This nonlinear behavior is commonly ...

Abstract: A mechanistic response model was recently developed at the University of Illinois to analyze geogrid base reinforced flexible pavements designed for low to moderate traffic volumes with a relatively thin hot-mix asphalt ...

Abstract: This article discusses the geogrid’s potential to reduce granular base shear flow. Researchers have previously acknowledged the geogrid’s potential to enhance the performance of roadways, but this study goes further to ...
