Slope paving is a broader term that covers a variety of methods for paving slopes, including colored slope paving, exposed aggregate slope paving, and slope paving with concrete pavers. <> Soil Stabilization Matting - Channel Application, Temp. US 160NW resists ultraviolet and biological deterioration, rotting, naturally encountered basics and acids. Also, ensure the contractor does not drop rock into place; otherwise, cracking or breaking may occur. YOU MUST NOTIFY US FABRICS BEFORE RECEIVING PRICING. They blanket the soil, protecting it from wind and water forces.

The State of Maryland pledges to provide constituents, businesses, customers, and stakeholders with friendly and courteous, timely and responsive, accurate and consistent, accessible and convenient, and truthful and transparent services. This handbook includes new and revised details for the various practices that are used in the development of erosion and sediment control plans. When evidence exists that the foundation depth is inadequate, obtain both the design and hydraulics engineers concurrence with a change order to deepen the foundation. Erosion control is an important element of successful slope protection. (One call ordering and delivery). 2019-07-30T13:44:04-04:00 Testing must follow the frequencies shown in Section 6-1, Sample Types and Frequencies, of this manual. /Length 5601 Place a layer (six inch minimum) of %PDF-1.4 Use all suitable material in the work. 0000014254 00000 n
Rock Channel Protection Paved Gutter 601.13 Basis of Payment 601.01 Description. conforming to the requirements of 710-03 Vinyl Coated Steel Fence Fabric, Class A Wire Diameter, except color. If using geotextile fabric, place on the smoothed foundation, overlap the edges at least 12 inches and secure with anchor pins spaced every three feet along the overlap. The heavier fabrics provide more strength and are less likely to tear when large class II or Class III boulders are placed on them. Slope protection structures are to be used where concentrated water will cause excessive erosion on existing and/or recent cut and fill slopes. Ensure that the contractor performs concrete finishing as specified and that the slope paving is cured by one of the specified methods. 3, METHOD B) (CY), ROCK SLOPE PROTECTION (NO. << 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. Before placement of the broken concrete, inspect the material and be sure the reinforcement has been removed flush to the surface of concrete. TenCate develops and produces materials that function to increase performance, reduce costs and deliver measurable results by working with our customers to provide advanced solutions. If the rock contains an excess of fines or inadequate voids, the desired results may be impossible to obtain. If your 20'x10' patio is to have a 6" base, then you should excavate a total area of 21' (20' +6" +6") by 11' (10' +6" +6"). Intermittent inspection of placement of slope protection, slope paving, and fabric operations. Ensure the equipment used during spreading does not crack the rock. trailer

Refer to Section 6-202, Responsibilities for Acceptance of Manufactured or Fabricated Materials and Products, of this manual for additional information. Fabric Class Class Largest rock gradation class used in slope protection 8 Classes I-VIII 10 Classes IX-XI Replace the 1st paragraph of section 73-3.028 with: Rocks for concreted-rock slope protection must comply with the gradation shown in the following table: Concreted-Rock Gradation . If necessary, order additional weep holes. with a minimum of 50% of the stones . For RSP Classes IX thru XI, use Class 10 RSP-fabric. Rock Slope Protection practice is intended for slopes too unstable for revegetation practices alone. Mirafi N-Series nonwovens combine high water flow rates, high soil interaction and durability while providing excellent soil particle retention. Refer to Section 4-96, Geosynthetics, of this manual for guidelines on inspecting and accepting rock slope protection fabric. 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. Copyright 2023 TenCate Geosynthetics Americas. 0000005658 00000 n

(800) 518-2290, Providing the most comprehensive geosynthetic lines in the industry. You can also lay bags of sand along problem areas in your landscape to keep soil from washing away and to redirect water. The concrete slope protection method consists of paving the embankment with portland cement concrete. 2.

2 0 obj To respond to the different problems associated with instability of rock faces, Geofabrics also has a broad range of independently verified rockfall mitigation systems. To provide the desired cleanliness, the contractor may need to sluice the rock or facing. 6 0 obj Take the following steps when inspecting the work and materials for slope protection: In addition to the general functions discussed above, the following items apply to specific types of slope protection. << Take care not to tear the filter fabric during installation. 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. Polypropylene is stable within a pH range of 2 to 13.
