CENOR Geology and Geotechnics Service organized last December 13th a visit to the A1 (Northern Motorway) site, designed by CENOR between 2012 and 2013, in order to observe the development of the embankment slope stabilization works between 10+100 and 11+100 km.

The adopted stabilisation solution consists on the enlargement of the existent embankment platforms, using materials with good mechanical characteristics (quarry debris). Due to space limitations, in some stretches, the slope of the new embankments is supported by gabion walls reinforced with geogrids.

Besides the geotechnical side, this intervention also comprises the road surface treatment and repaving.
