Abstract: 
In order to gain some insight about the mechanisms and the phenomena involved in the transfer of forces between a high modulus subbase reinforcement and the surrounding materials, a finite-elements system has been utilized. The influence of the reinforcement on the total paved road structure was assessed. Several issues were addressed like simulation of the bond characteristics of the reinforcement, simulations of the no-tension carrying characteristics of the aggregate materials, simulation of the propagation of discrete cracks in the pavement and their interaction with the surrounding materials. Practical design charts are presented for reinforced paved roads on soft subsoil.
