Material for stone blank et shall be deposited for protection around piers or abutments as shown on the plans. Th e stones shall be placed individually to form a reasonably compact mass. Spaces between the larger stones shall be filled with stone or spall of suitable size to leave an even surface conforming to the contour required. Stone fill and stone blanket shall be placed on the slope in a well-knit, compact and uniform layer. The surface stones shall be chinked with smaller stone from the same source.
b.Riprap Stones for riprap shall be placed upon a slope prope rly graded and compacted as called for. When required, the bottom of the ripr ap shall be placed in a trench at the toe of the slope. Plain riprap shall be placed f ull depth in one operation without special handwork and shall be placed approximately true to the required slope line and grade and be uniform in appearance. Hand laid riprap shall be random rubble, hand laid stones for the full depth placed in one operation to secure interlocking of all face stones and stones placed as backing. Larger stones shall be laid at the base of the slope. The stones shall be lai d in close contact with the long er axis perpendicular to the plane of the slope to stagger joints. Except when required to be grouted the openings between the stones in all riprap shall be filled with spall, or rocks securely rammed into place. Riprap shall be placed on the slope in a well-knit, com pact and uniform layer. The surface stones shall be chinked with smaller stone from the same source.
