Provide grooves that are ⅛ in [3
6 Space grooves in a random pattern from ½ in to ⅞ in [12 mm to 19 mm] centers.
Continuously remove resulting slurry or residue immediately following grooving operations. Clean the lands and the grooves and leave the surface free of slurry residue and other deleterious material. Remove grooving residue by flushing, vacuuming, or other methods approved by the engineer.
513.5MEASUREMENT and PAYMENT
1 The engineer will measure Class A Concrete, Class B Concrete, and ClassS Concrete
as one complete unit or by the cubic yard [cubic meter]. The engineer will compute volumes from the neat lines specified. 2 The department will pay as follows:

Reinforcing Steel
514.1DESCRIPTION
1 This section describes the requirements for furnishing and placing reinforcing steel.
514.2MATERIALS
514.2.1 Reinforcing Steel 1 Provide materials in accordance with the following:
Material
Subsection
Reinforcing Steel
811.1
514.2.2 Reinforcing Steel Supports and Ties 1 When using metal supports, provide with legs curved to form a hook, with the ends
at least ⅛ in [3 mm] above the form work. Protect metal supports for uncoated reinforcing steel that are in contact with the exterior surface of the concrete by galvanizing or coating with plastic or epoxy. Ensure that coatings do not chip, crack, deform, or peel. Extend protection at least ½ in [12 mm] above the form work. Apply plastic protection by dipping; ensure a minimum thickness of 1/16 in [2 mm] at points of contact with form work. 2 Coat metal supports for epoxy-coated reinforcing steel completely with epoxy or plastic.
Use galvanized metal supports for galvanized reinforcing steel. For coated bars, provide support legs in accordance with the dimensional and coating requirements for uncoated bars. 3 Use plastic- or epoxy-coated tie wires for epoxy-coated reinforcing steel, galvanized
tie wires for galvanized reinforced steel, and stainless-steel tie wires for use with mechanical tying equipment. 514.2.3 Mechanical Reinforcing Steel Splices 1 Provide mechanical reinforcing steel splices consisting of a lap or butt splice system
capable of developing at least 125 percent of the specified yield strength for the reinforcing steel. When epoxy coating is specified, shop- or field-coat the mechanical splice and adjacent material as necessary with epoxy in accordance with Subsection 811.1, Reinforcing Steel, or seal the splice with an approved heat-shrink plastic sleeve in accordance with the sleeve manufacturer’s recommendations.
