Design of highway rock slopes catchment area

This paper discusses the importance of block catchment areas at the base of highway rock slopes through problem conceptualisation and application of techniques for designing these structures. Rockfall catchment is defined as the area between the edge of the highway pavement and the base of the rock slope, which may also coincide with the protection ditch at the base cut. In terms of rockfall, this structure has the function of preventing this process from reaching the highway surface. Road projects should include prices to build these structures, which also have the important function of surface drainage.
