For gabion structures, grade the foundation for a width equal to the width of the gabion plus 2 feet. Where gabions are set on rocky foundations, place 6 inches of select granular backfill under the baskets.

253.08 Revet Mattresses. Add the following:

(a) Design Prefabricate articulated concrete block revetment mat as an assembly of concrete blocks, with specific hydraulic capacities, laced with revetment cables. Articulated concrete block revetment mat may be assembled on-site. The concrete cells or blocks may be open or closed as described and may vary in dimension. The blocks will be square and should not be less than 8” or more than 16” in dimension. The open cell units have two (2) vertical openings of rectangular cross section with sufficient wall thickness to resist breakage during shipping and installation. Secure all blocks in any given mat with a minimum of two (2) cables each.

Incorporate interlocking surfaces of each block that minimize lateral displacement of the blocks within the mats when lifted by the longitudinal revetment cables.

Interlocking surfaces must not protrude beyond the perimeter of the blocks to such an extent that they reduce the flexibility or articulation capability of the cellular mats or become damaged or broken when the mats are lifted during shipment or placement. Once in place the interlocking surfaces of the mats shall minimize the lateral displacement of the blocks even if the cables should become damaged or removed. A minimum of 18° between any given row or column of blocks in the uplift direction and a minimum of 45° in the downward direction must be maintained in the mats. Insert cables into the mats allowing for lifting loops at one end of the mat with the corresponding cable ends spliced together to form a lifting loop at the other end of the mat. Insert cables after sufficient time has been allowed for the concrete to complete the curing process. Place the articulated concrete block revetment mat on the filter fabric.

(b) Physical Requirements

PHYSICAL REQUIREMENTS

(c) Grading

Grade the slope to a smooth plane surface to achieve good contact between the slope face and the geotextile, and between the geotextile and the entire bottom surface of the articulated concrete blocks. Remove or re-grade slope from all deformities, roots, grade stakes, and stones which project normal to the local slope face. Place compacted homogenous material to fill all holes, “pockmarks”, slope board teeth marks, footprints, or other voids greater than 1.0 inch in depth normal to the local slope face. Place compacted homogenous material to fill all grooves or depressions greater than 0.5 inches in depth normal to the local slope face with a dimension exceeding 1.0 foot in any direction. Uniformly compact the slope and slope face as directed by COR. Excavate and prepare anchor trenches, flanking trenches, and toe trenches or aprons according to the plans. Uniformly grade the anchor trench hinge-point at the top of the slope to prevent dips or bumps greater than 0.5 inches over or under the local grade. Uniformly grade the anchor trench hinge-point to the width that allows good contact between the articulated concrete blocks and the underlying grade at the hinge point. Obtain approval of the subgrade from the COR prior to placement of filter fabric and articulated concrete blocks.

(d) Placement

Place the articulated concrete blocks on top on the subgrade. No individual block within the plane of placed articulated concrete blocks shall protrude more than one inch or as otherwise specified by the COR. If placed as a large mattress, use a spreader bar or other approved device to lift and place the mats in the proper position with a crane or other approved equipment. Place mats side-by-side and/or end-to-end so that they abut one another. The mats shall be laid from the downstream end of project to the upstream end, so the geotextile joints are shingled to direct flow over the joint and to prevent undermining. Intimate contact with the subsurface is critical to the systems performance in the field. The gaps between each mat shall not be greater than 2 inches. The upstream two (2) rows of each mat system shall be entrenched and buried at a 45° downward direction into the ground. Type 2 riprap shall be used to fill the entrenched edge. Backfill the trench flush with the top of the blocks.

253.09 Acceptance. Delete the second paragraph and add the following:

Material for gabion structures and revet mattresses will be evaluated under Subsections 106.02,106.03, and the following:

(a) All units shall be sound and free of defects that would interfere with either the proper placement of the unit or impair the performance of the system. Surface cracks incidental to the usual methods of manufacture, or surface chipping resulting from customary methods of handling in shipment and delivery, shall not be deemed ground for rejection. Cracks exceeding 0.25 inches in width and/or 1.0 inch in depth shall be deemed grounds for rejection. Chipping resulting in a weight loss exceeding 10% of the average weight of a concrete unit shall be deemed grounds for rejection.

Typically the required mowing width will be tree line to tree line. Required mowing width will vary from a minimum of three (3) to five (5) feet outside the ditch line or throughout the previously mowed area whichever is greater. Contactors are encouraged to inspect roads before submitting a quote. No additional payment will be made for variable widths.

All cut and fill slopes too steep to mow with equipment shall be cut to a five (5) inch maximum height by hand or other method approved by the COR to a minimum of six (6) feet from the ditch line of cuts and the shoulder of fill areas.

All rocks, logs, or other objects dislodged by the Contractor’s operation that fall into the drainages or traveled way shall be removed. This also includes any reasonable size limbs already lying in the right-of-way.

The contractor shall be responsible for damage to culverts, marker posts, guardrails, signs, etc. Damaged items shall be replaced at the Contractor’s expense.

Limbing will consist of cutting limbs as close to the tree as possible from tree line to tree line 14’ in height.

Any cuttings that may fall in the traveled portion of the roadway or that may clog drainages shall be taken a minimum of 3 to 5 feet beyond the treeline unless chipped or broken into small pieces by the equipment. Trees that are accidentally damaged by the Contractors operation that are unsightly or would impair growth shall be cut five (5) inches above ground and removed from right-of-way.
