Innovations on components and testing for precast panels to be used in reinforced earth retaining walls

The present article introduces three innovations related to precast concrete panels to be used in reinforced earth retaining wall systems. These innovations concern the anchor system of the panel, the set-up of the pull-out test to assess the effectiveness of the anchors and the use of fibres as reinforcement. The viability of all this innovations has been proved by an experimental research program. Results show the advantages of these innovations in terms of performance and of production process.
