If additional fill material is required to bring the slope to the proper grade, it shall be of the same type material as that required for the slope protection foundation. Immediately prior to placing the concrete, the area to be covered shall be thoroughly dampened. The Portland cement concrete shall be placed in alternate sections. Each individual section shall be placed by starting at the lowest extremity of the section and progressing upward on the slope. The reinforcement shall not extend through the construction joints and the bond between sections shall be broken by the application of approved asphalt cement on the edges of the previously placed slabs. 5-119 The surface of the concrete shall be float finished in accordance with the requirements of Section 502 - Structural Concrete and textured by applying a uniform light broom finish using an approved broom. An edging tool shall be used on the surface edges of each section and a groover at the transverse centerline of each section. The exterior surface from the edging or grooving shall be finished to match the interior surface. Construction procedures shall be in accordance with Section 502 - Structural Concrete.
513.04 Crushed Stone Crushed stone shall be placed on granular material as shown on
the Plans. The finished slope shall be worked to present a smooth and uniform surface.
513.05 Drains or Weep Holes Drains or weep holes through the slope protection shall
be pipe of the size and shape shown on the Plans and shall be constructed of approved cast iron, tile, fiber or other material that will maintain its shape and alignment during placement of the concrete. Care shall be taken not to cover the drains when installed, or when concrete is placed.
513.06 Method of Measurement Slope protection will be measured by the number of
square yards of surface area acceptably covered in accordance with the Contract.
513.07 Basis of Payment The accepted quantity of slope protection will be paid for at
the Contract unit price per square yard. Payment will be full compensation for excavating, shaping and compacting the slope prior to placing bedding and slope protection and shall also include the bedding material.
