shall comply with ASTM A996.
1009.01.3 Cold-Drawn Steel Wire: Plain wire shall comply with
ASTM A1064 with the following amendment: For material testing over 110,000 psi tensile strength in high strength applications such as spirals and ties, reduce the 25 percent minimum reduction in area by 5 percent for each 10,000 psi increment of tensile strength exceeding 110,000 psi. Deformed wire shall comply with ASTM A1064.
1009.01.4 Steel Welded Wire Reinforcement: Comply with
ASTM A1064. Use deformed reinforcement for bridge structures.
1009.01.5 Stainless Deformed Reinforcing Steel: Conform to
ASTM A955, Type 316LN UNS Designation S31653, UNS Designation S31803, or UNS Designation S32304.

with ASTM A767.
1009.01.7 Epoxy Coated Reinforcing Steel and Patching
Materials: Use products from the Approved Materials List and comply with ASTM A775.
1009.02 BAR SUPPORTS AND TIE WIRES. Bar supports (chairs)
shall be metal wire. The bottom of bar supports shall be coated with an acceptable epoxy or plastic material for a minimum distance of 2 inches from the point of contact with the forms. Metal chairs in contact with the metal forms shall be hot-dipped galvanized, electroplated with zinc (GS Grade), epoxy coated, or stainless steel. Metal tie wires and bar supports shall be coated fully with an acceptable epoxy, plastic or nylon material if using epoxy coated steel.
1009.03 Dowel Bars.
1009.03.1 PAVEMENT DOWEL BARS: Steel dowel bars shall
comply with 1009.01.1, 1009.01.2, or 1009.01.3. Dowels shall have a uniformly round cross section and shall be saw cut, smooth and free of burrs, projections and deformations. Coated dowel bars shall be undercoated with an adhesive and given an outer coat of polypropylene or polyethylene. Coated dowel bars shall comply with AASHTO M 254. For PCCP, place coated dowel bars in approved dowel bar assemblies in accordance with the plans.
1009.04 Steel Strand for Pre-Stressing and Post-
TENSIONING. Strand shall comply with ASTM A416. The strand manufacturer shall submit to the Construction Section three copies of Certificates of Analysis of all test results as stipulated in ASTM A416, and as part of this certificate, shall provide the modulus of elasticity of that particular mill heat of strand. The Department reserves the right to conduct inspections at the site of manufacture and to have all tests witnessed by its inspector. The data from the manufacturer's typical curve shall be used when computing the required elongation for each strand.
1009.05 Anchorages and Hardware for
PRESTRESSING. Anchorages, including hold down and miscellaneous hardware, shall be sampled in accordance with the Materials Sampling Manual and submitted to the Construction Fabrication Engineer for acceptance after evaluation or testing.
1009.06 WIRE ROPE. Wire rope shall comply with Federal
Specifications RR-W-410G or the latest federal specifications and the following: Comply with Table 1009-1 when selecting the type and classification of wire rope. When wire joints are necessary, they shall be electrically butt -welded; and in the stranding operation, no two joints in any strand shall be closer than 25 feet, except for filler wires. Table 1009-1 General Wire Rope Classification and Usage Type Classification Usage I 1. (6x7) Haulage rope, for use where strength and durability are desirable, but not much bending is required. May be used as single line for pulling load, but not suitable for sheave work.
2.(6x19) Most widely used for cranes, derricks, dredges, draglines and scrapers. This classification is very rugged, withstands abrasion well and is generally suited for all-around use.
3.(6x37) For hoisting rope where maximum flexibility is required; for instance, hoisting rope that runs over small sheave on draglines. II 1. (8x19) High speed elevator rope. III (Marine) 1. (6x6) Deck lashing ropes.
2.(6x12) Running ropes.
3.(6x24) Mooring lines.
4.(6x3x7) Spring lay.
5.(6x3x19) Spring lay.
6.(6x42) Tiller or hand control rope. IV (Special) 1. (18x7) Nonrotating (for drill rigs)
1009.07 WIRE ROPES FOR MOVABLE BRIDGES. See Sections
821.07 31, 821.07.32, and 821.07.33.
