On design principles of reinforced pavement structures - the COST 348 REIPAS action

Resumo

The paper is summarizing the development work for reinforcement of pavements and structures in the COST 348 REIPAS Action. Design approaches developed either for the utilization of geosynthetic reinforcement materials or for the utilization of steel grids are referred. The basic common principles of reinforcing practice is inserting or laying the steel or geosynthetics mesh below or underneath the pavement either during the maintenance or reconstruction of existing roads or construction of new sections. The COST 348 action is taking a step towards practicable guidelines for the structural design and execution of reinforced pavements and road sub-bases and to reach a consensus on the methods to determine relevant material parameters essential for analysing or predicting the behaviour of the reinforced structures.
