• All layers of secondary reinforcement must extend from the face of the wire forms for Type A and Type B slopes, from the face of the geosynthetic wraps for Type C slopes, and from the back of the gabions for Type D slopes, to a minimum of the full length of the longer layer of primary geosynthetic reinforcement directly above or below the layer of secondary reinforcement. Place secondary geosynthetic in continuous lengths perpendicular to the slope face whenever possible. Overlap adjacent sections of secon dary geosynthetic a minimum of 2 inches along parallel roll edges. If the length of primary reinforcement from the slope face is less than the roll width of the secondary reinforcement, the secondary reinforcement may be placed in continuous strips parallel to the slope face. Overlap secondary reinforcement in the roll direction (old roll to new roll) a minimum of 1 foot. When placed in lengths perpendicular to the slope face, partial rolls of secondary reinforcement must extend a minimum of 7.5 feet from the slope face before a roll direction (old roll to new roll) overlap is allowed. For Type A and Type B slopes, slit the secondary geosynthetic a length only as necessary to allow installation of the geosynthetic at support struts.
• All geosynthetics, except for face wraps of Type C Slopes, must be backfilled before the end of the workday. Place geosynthetic to lay flat, pulled tight and anchored in place until backfill is placed. Place geosynthetic within ±1/2- inch of the plan elevations and to the minimum length indicated. Do not dump fill directly onto exposed geosynthetics. Place fill on previously spread material and blade out. Place and distribute material without wrinkling the geosynthetic.
• Place GRS slope caution tape as shown on the Standard Drawing . GRS slope caution tape is to be customized detectable underground warning tape as shown on the Standard Drawing .
• Grade the surface of the fill only as necessary to facilitate surface drainage. Seal surface with a smooth drum roller at the end of each workday. No vehicles are allowed on the geosynthetic until a minimum of 8 inches of loose backfill has been placed. Sudden braking and sharp turning of any vehicle, including tracked equipment, on reinforced fill is prohibited. Correct any disturbance or distortion of geosynthetics due to operation of vehicles or equipment, at no additional cost to the Department .
than 0.5(H):1(V). Type A Slopes are not allowed within a 500- year floodplain.
1.a Wire Mesh Forms. Use wire mesh forms to establish a stepped face to the slope face ratio and dimensions indicated. Internally brace wire mesh forms to maintain verticality of step faces. Place preformed wire mesh units on the exterior (outside) of all primary and
