Mirafi N-Series nonwoven polypropylene geotextiles are used for soil separation, drainage in Transportation, Building Site, and Water Infrastructure projects such as subsurface drainage, permanent erosion control and roadway separation applications. Erosion Control Fabrics featured here have been used in a wide range of applications including slope stabilization, sediment containment, runoff filtration, home protection, and vegetative regrowth. Observe construction to ensure the contractor does the placing, finishing, and curing as specified. (see Riprap Slope Protection Worksheet). 72-2.02B Fabric Fabric must be RSP fabric that complies with the class shown in the following table: 72-4 SMALL-ROCK SLOPE PROTECTION 72-4.02 MATERIALS The best slope protection type for a given situation depends on the conditions where the installation is to be made, availability of protection material, cost of the various types, and protection desired. 0000005658 00000 n

The equilibrium soil-to-geotextile system that allows for adequate movement of a liquidin the plane of the geotextile over the service lifetime of the application. For RSP Classes I thru VIII, use Class 8 RSP-fabric which has lower weight per unit area and it also has lower toughness (tensile x elongation, both at break) than Class 10 RSP-fabric. It consists of a layer of very large stones interlocked together and acts as a barrier on slopes that are unstable because of seepage problems or in areas that are receiving a large concentrated flow. Angular shaped rock may be used on any planned slope. Temporary structures shall be left in place until adequate vegetation and the permanent . 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. 2, METHOD B) (CY) (ENGMET), ROCK SLOPE PROTECTION (NO. Riprap is a permanent layer of large, angular stone, cobbles, or boulders typically used to armor, stabilize, and protect the soil surface against erosion and scour in areas of concentrated flow or wave energy.

Refer to Section 4-96, Geosynthetics, of this manual for guidelines for inspecting and accepting rock slope protection fabric. Shop Lowe's for solutions to control erosion on slopes, as well. Rock Slope Protection practice is intended for slopes too unstable for revegetation practices alone. Values shown are based on Table 873.3A dimensions and an assumed specific gravity of 2.65. Before construction of any type of slope protection, review the plans, Standard Specifications, special provisions, any pertinent preliminary test data, and the location of the installation. To respond to the different problems associated with instability of rock faces, Geofabrics also has a broad range of independently verified rockfall mitigation systems.
