(3) Surfaces to be buried and culvert surfaces above finished ground that are not visible from the traveled way or a walkway.

Begin finishing as soon as the forms are removed. Remove fins and irregular projections from all surfaces that are exposed or will be waterproofed. Remove bulges and offsets with carborundum stones or discs. Remove localized, poorly-bonded rock pockets and honeycombed concrete, and replace with sound concrete or packed mortar. Fill all holes with mortar in the same cement/aggregate ratio as the concrete being finished, and float to an even, uniform finish. A bonding agent may be used with the approval of the CO.

Clean and point form tie cavities, holes, broken corners and edges, and other defects. Saturate the area with water. Finish the area with mortar that is less than 1-hour old. After the mortar is set, rub it (if required) and continue curing. Match exposed surfaces to surrounding concrete.

Carefully tool and remove free mortar and concrete from construction and expansion joints.

Leave joint filler exposed for its full length with clean, true edges.

Rub or grind bearing surfaces on piers and abutments to the specified elevation and slope.

If the final finished surface is not true and uniform, rub it according to Subsection 552.16(b).

Delete paragraph (b) and substitute the following:

(b) Class 2 – rubbed finish.

(1) Finish the following surfaces with a Class 2 rubbed finish:

(d) Surfaces of pedestrian undercrossings except floors and surfaces to be covered with earth;

(e) Surfaces above finished ground of culvert headwalls and endwalls when visible from the traveled way or walkway;

(f) Inside surfaces of culvert barrels higher than 48 inches that are visible from the traveled way. Finish for a distance inside the barrel at least equal to the height of the culvert; and
