Protection

Protection involves intercepting and retaining rockfall before it reaches the roadway once the event has occurred. Techniques include the construction of catchment ditches, rockfall barriers and fences, rockfall sheds, earthen or engineered rockfall embankments, and hybrid fence and draped mesh systems that allow controlled rockfall descent. These remedial methods typically involve the most maintenance of the three approaches, as well as more significant visual impacts. Two of the most common protection measures are rockfall barriers and catchment ditches, as shown below.
