Click on the to send the number to the Method A is used where the stability of the rock slope protection is considerably dependent on the manner in which the individual rocks are placed. Refer to Section 4-96, Geosynthetics, of this manual for guidelines on inspecting and accepting rock slope protection fabric. Type R. Use stones between 50 and 250 lb. They are designed to protect against raveling-type rockfall that involves small-volume slope failures (up to about 7.6 m3 or 10 yd3) or blocks up to 1.5 m (5 ft), depending on the strength of the mesh used (Muhunthan et al. Neoloy Tough-Cells in slopes prevent erosion, enable drainage and stabilize the slope to provide a green surface cover. Rock Slope Armor is a layer of rock, such as ditch lining rock, cobble rock, concrete rubble, or riprap, which is hand or mechanically placed on an erodible soil slope. If the fabric is joined by stitched seams, stitch with contrasting colored yarn. Rock Slope Protection Fabric, used in slope stabilization projects (see Technical Note on Rock Slope Protection / Rip Rap) When required by the Project Engineer, a Certificate of Compliance for each type of fabric being used should be issued by the supplier and furnished to the Engineer. Refer to Section 4-96, Geosynthetics, of this manual for guidelines for inspecting and accepting rock slope protection fabric.
