Slope Protection consists of rock, concrete, or concreted rock or slope paving ROCK SLOPE PROTECTION ROCK SHOULD DEMONSTRATE Stability: Angular shapes may be used on any planed slope Durability: Resist degradation and have a durability of 52 minimum (Caltrans) Consistency: Product is the same load after load. 2 0 obj Standard contract items and descriptions for Caltrans projects. To provide the desired cleanliness, the contractor may need to sluice the rock or facing. endobj Properly designed slope protection and stabilization has to include two components: a vegetational-biological and a mechanical-structural component. At the start of gabion placement, require the contractor to verify the minimum unit weight of the gabions to ensure it meets specifications.

The samples will be crushed in the laboratory to sizes needed to perform tests. You can also lay bags of sand along problem areas in your landscape to keep soil from washing away and to redirect water. A geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. Riprap can be used to stabilize slopes to prevent erosion and provide support. 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. /Filter/FlateDecode RG12N Nonwoven Geotextile with a 300 lbs grab tensile strength and a flow rate of 65 gallons a minute per square foot. 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 Ensure the timber spacers are of the required material and spaced as planned. Provide filter fabric in accordance with DMS-6200, Filter Fabric. For protection stone riprap, provide Type 2 filter fabric unless otherwise shown on the plans.

For maximum effect, both components must be integrally planned prior to road construction. Where applicable, inspect the footing areas and foundations for evidence of instability or areas where hydrostatic pressures may develop. The contract will identify the designated method. 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. (see Riprap Slope Protection Worksheet). Stable rock sizes and flow depths for riprap-lined channels having gradients between 2 percent and 40 percent may If the rock contains an excess of fines or inadequate voids, the desired results may be impossible to obtain. When shotcrete is to be used, review Section 4-53, Shotcrete, of this manual. Soil Stabilization Matting - Channel Application, Temp. 4 0 obj Consult engineer to ensure applicable design requirements are met. Neoloy Tough-Cells in slopes prevent erosion, enable drainage and stabilize the slope to provide a green surface cover. If excess concrete remains on the surface, the finished product, when used in streams, will be too smooth and, along the protection, velocities will increase beyond those intended during design. Lap 6'' min. When slope protection is paid by weight, refer to the discussion of weighing and metering procedures in Section 3-902E, Weighing Equipment and Procedures, of this manual. 2019-07-30T13:47:33-04:00 1, METHOD B) (TON), ROCK SLOPE PROTECTION (NO.
