SECTION 905 – REINFORCEMENT METALS
905.01 Reinforcement Steel
Provide reinforcement steel manufactured at an AASHTO NTPEP (National Transportation Product Evaluation Program) certified mill. For a list of NTPEP certified mills, see the following webpage: https://data.ntpep.org/REBAR/Audits. For reinforcement steel, submit a certification of compliance as specified in 106.07. Attach copies of the mill certifications for each heat of reinforcement steel. The ME will randomly sample an d test heats of reinforcement steel for quality assurance. The ME will randomly inspect and sample galvanized and epoxy coated reinforcement steel for quality assurance.
905.01.01 Reinforcement Bars
Use deformed bars according to ASTM A 615, Grade 60. Fabricate using the detailing dimensions for hooks, bends, and tolerances according to the CRSI Manual of Standard Practice. Bend bars using the cold method with positive powered machines in the shop or field. Compute the weight of reinforcement steel according to ASTM A 615. If specified, galvanize according to ASTM A 767, Class I. Fabricate bends and details before galvanizing. If specified, apply epoxy coating according to ASTM A 775.
905.01.02 Spiral Reinforcement
Use spiral reinforcement that is plain round hot-rolled steel bars according to ASTM A 615, Grade 60. Compute the weight of reinforcement steel according to ASTM A 615.
905.01.03 Welded Wire Reinforcement
Use plain or deformed steel welded wire reinforcement according to ASTM A 1064. When used for concrete pavement, use welded wire reinforcement mats at least 5 feet in width. When approved as an alternate to galvanized reinforcement bars, use galvanized welded wire reinforcement that meets the requirements of ASTM A 641, Table 1, Class 1.
905.01.04 Structural Shapes, Plates, and Bars
Ensure that structural shapes, plates, and bars used for reinforcement or other miscellaneous embedded metal work conform to the requirements for structural steel specified in 906.01. Galvanize according to ASTM A 123.
905.01.05 Dowels
Use plain reinforcement bars according to ASTM A 615, Grade 60. Galvanize according to ASTM A 123.
905.02 Prestressing and Post-Tensioning Reinforcement
The ME will sample and test each heat of steel reinforcement prior to use for acceptance. For prestressing strand, the ME will test two 4 foot cables with flame cut ends and one 1 foot piece with sawcut ends from each heat. For high -strength alloy bars, the ME will test one 6 foot bar from each heat. For post-tensioning, the ME will test one 6 foot cable (between fittings) from each reel or one 6 foot bar (between threads) from each lot. Provide a certification of compliance as specified in 106.07. Attach the mill certification for each heat used with the certification of compliance.
905.02.01 High-Tensile-Strength 7-Wire Prestressing Strand
Use high -tensile-strength, low -relaxation 7-wire strand for prestressing reinforcement according to ASTM A 416, Grade 270. When specified, use grit impregnated epoxy-coated steel strands according to ASTM A 882.
905.02.02 High-Tensile Strength Alloy Bars
Use high-tensile strength alloy bars for prestressing or post-tensioning according to ASTM A 722.
