In recent years, the need to increase pavement service life and guarantee high performance has turned a greater attention on the use of pavement reinforcements. In this paper, the effectiveness of geogrids as reinforcement of flexible pavements has been investigated. This study focuses on the performance of pavement reinforced with geogrids, in term of reducing of rutting, under traffic loads. Analyses on numerical models of different road have been performed by using the finite element method. The results obtained show that the glass fiber grids can be used to improve the performance of flexible pavements and can provide a relevant contribution to the resistance to crack propagation and to the reduction of permanent deformations.
