Motorway crash barriers

The crash barriers that we see on the sides of our roads, both on flat terrain and on bridges, must satisfy a series of requirements.

It is necessary to verify, first of all, that stray vehicles do not go through the barrier, that they are returned to the road with shallow trajectories, and that the accelerations felt by the passengers are not excessive.

Principia has collaborated several times with designers of crash barriers, conducting calculations and comparisons with the results of full-scale tests, normally performed in the Cidaut facilities in Valladolid. The object is to guarantee that the barriers satisfy the applicable European regulations.
