852.1DESCRIPTION—This work is construction of a reinforced cement concrete channel, with embedded

stones or solid precast blocks.

852.2MATERIAL—

• Class A Cement Concrete. Section 704

• Reinforcement. Section 709.3

• Precast Concrete Blocks. Section 713.2(a)

• Joint Sealing Material. Section 705.4(b) or (c)

• Premolded Expansion Joint Filler. Section 705.1

• Asphalt Impregnated Paper. Section 727

• Stones. Section 850.2

852.3CONSTRUCTION—As shown on the Standard Drawings and as follows:

Excavate to the required paving depth. Remove unsuitable material below the bottom of the paving and replace with suitable material. Thoroughly compact and finish the entire foundation area to a firm, even surface. Mix, place, finish, and cure the concrete, as specified in the applicable parts of Section 1001.3. Hold the reinforcement firmly in position during the placing of concrete. Pave in uniform 10-foot lengths or sections except where shorter sections are necessary for closures or curves. Form intermediate joints between sections, with two t hicknesses of one -ply asphalt impregnated paper cut neatly to the paving cross section. Place premolded expansion joint filler, 1/2 inch thick, cut to conform to the paving cross section at the ends of curved sections, at intervals of not more than 100 feet, at the end of a day's work, and where paving is adjacent to a rigid structure. Use premolded expansion joint filler that has a depth of 1/2 inch less than the paving depth and press firmly against the adjacent concrete. Seal the joint top with joint-sealing material. Protect paving from the elements, flowing water, or other disturbances until curing is completed.

852.4MEASUREMENT AND PAYMENT—

For removal of unsuitable material of the same class of excavation for the ditch or channel above the paving.
