WebPlotting the 0.25H:1V slope on the roadway design cross-section, and assuming a cut widening. in the 20-30 foot range to provide rockfall catchment, gives a maximum new cut slope height of. approximately 80 feet. Step 3 - Select the appropriate catchment area design chart based on slope ratio and slope height. WebCatchment Area– The area between the roadway edge of pavement and the base (toe) of a rock cut slope used to restrict rockfalls from the roadway. The term is synonymous with ditch, rock fallout area, rockfall ditch, rockfall catch ditch, and catch ditch. WebBased on cut slope angle and height and catchment area slope, the design charts estimate the catchment area widths required to retain percentages of rockfall ranging up to 99%. Design guidelines and step-by-step design procedures are presented and illustrated with three worked example design problems. tai nghe soundcore life p2 mini
