Situación inicial
Heavy rainfall in the area induced large rockfalls above the RD4 road. Almost 40 cubic meters of rock detached from the face above the RD4. The blocks hit the road and eventually ended up in the Hérault river below the RD4. Rockfalls of such size can cause considerable damage to the road infrastructure and harm road users.
Descripción
Two four meter high GBE-1000A rockfall barriers were installed. The combined length of the barriers amounts to 138 meters. Painted barrier posts guarantee a better integration of the barrier into the landscape. In addition, SPIDER S3-130 mesh was used to stabilize loose blocks of the outcrop. This way, blocks with large volumes can be kept in place. The combination of the rockfall barriers and the slope stabilization keeps the road operable at most times while also increasing the safety of the road users.
