Slope protection is usually needed to protect the upstream slope against erosion due to wave action. Obtain rock samples for acceptance tests. These products were developed to meet specific agency (DOTs, MTOs, etc.) 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. ), Geocomposite Wall Drain (w/ 6oz on 1 or 2 sides - Please specify.). <> XYo[unHCih,(~ t@K{ y.EmvKhy?_\F6.nO?iV5FlD,#t~J7z@Al.z_ooA=H /$Q-Aav. 0000011079 00000 n Geofabrics offers a range of engineered slope, embankment and retaining wall solutions of use in transport infrastructure projects. The small-rock slope protection method consists of excavating and backfilling the footing trench, placing rock slope protection fabric as shown, and placing small rocks on the slope. Without proper slope protection, a serious erosion problem known as "beaching" can develop on the upstream slope. Nominal RSP class by median particle diameterb Nominal median Ensure that the contractor performs concrete finishing as specified and that the slope paving is cured by one of the specified methods. Temp. The method is particularly adaptable to locations where high-velocity flow is not detrimental, but desirable, and the hydraulic efficiency of smooth surfaces is important. The concreted-rock slope protection method is used where large rock is not economically available in large quantities, yet a heavy, service type of protection is required. <> .
