Experimental and numerical studies of the geosynthetics reinforced platforms laid over soft subgrade soil

Abstract

Six full-scale unpaved test sections were constructed to investigate the benefit obtained from inclusion of geosynthetic layer. Two geotextiles were placed at the interface between the base layer and the subgrade. The results allowed the estimation of reinforcement efficiency. In addition, a numerical model coupled between the discrete element method and the finite element method has been calibrated based on the experimental results.
