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. Rock mesh slope protection is a technique to control rockfalls . 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.

Without proper slope protection, a serious erosion problem known as "beaching" can develop on the upstream slope. Erosion control devices provide direct protection to the soil surface therefore, are considered one the best measures for preventing erosion. Otherwise, placement could result in what is known as rockers or unstable rocks. 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.

Before placement of the broken concrete, inspect the material and be sure the reinforcement has been removed flush to the surface of concrete. To ensure the success of Method A, ensure that the bearing of rocks from one to the other follows specifications and that the use of chinking rocks is limited to filling voids. When shotcrete is to be used, review Section 4-53, Shotcrete, of this manual. Chapter 4: Construction Details, Section 72: Slope Protection, Direction of flow and angle of impingement at various water stages, Capability of adjacent soil types to resist erosion from wash and eddy currents. If extensive slope protection problems are anticipated or encountered during construction, refer these to the design engineer and the project manager, who may in turn obtain the advice of the Caltrans Bank and Shore Protection Committee..

If the fabric is joined by stitched seams, stitch with contrasting colored yarn. Slope protection is usually needed to protect the upstream slope against erosion due to wave action. For measuring concrete or shotcrete, refer to Sections 4-90, Concrete, or 4-53, Shotcrete, of this manual. At the terminals of protection, ensure the contractor is particularly careful to avoid erosion and undercutting. Flat or needle shaped rock must not be used unless the individual rock thickness is greater than 0.33 times the length. 1 Draw Down Device, Sediment Basin Schematic - Vert. 0000002313 00000 n 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. Properly designed slope protection and stabilization has to include two components: a vegetational-biological and a mechanical-structural component. Copyright Maryland.gov. The plans indicate the minimum depths of foundations. with a minimum of 50% of the stones . 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.
