The following common types of slope protection are covered in this section: Other protective devices are used in conjunction with highway construction, and when used, they are included in the contracts special provisions. This article studies the mechanical properties and stability of CC slope protection by comparing it with conventional material (shotcrete). 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. 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"). 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. When rock slope protection fabric is required for either method, ensure the contractor places the fabric before placing the rock slope protection. Weight will vary based on density of rock available for the project. Check the area to be protected to ensure that the required expansion joints are in place. endobj 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. concreted-rock slope protection (1/2 t, class vii, method b) (ton) 723215 concreted-rock slope protection (1/4 t, class v, method b) (cy) 723220 concreted-rock slope protection (1/4 t, class v, method b) (ton) 729011 rock slope protection fabric (class 8) 729012 rock slope protection fabric (class 10) 750020 rigid rail fall protection system trailer << /Size 489 /Info 438 0 R /Root 464 0 R /Prev 989742 /ID[<23d8c9b814a334ef8bf252da6b923edc><23d8c9b814a334ef8bf252da6b923edc>] >> startxref 0 %%EOF 464 0 obj << /Pages 445 0 R /Type /Catalog >> endobj 487 0 obj << /S 1440 /Filter /FlateDecode /Length 488 0 R >> stream 0000004037 00000 n 0000004014 00000 n Mirafi 1100N, 1120N and 1160N are heavy weight nonwoven geotextiles for more severe or extremely harsh conditions, such as rip-rap and revetment applications.
