3301.1SCOPE
Provide deformed and plain reinforcing steel for use as reinforcement in concrete construction.
3301.2REQUIREMENTS
Provide reinforcement bars, other than wire, meeting the requirements of the following AASHTO specifications for the size, type, and grade as shown on the Plans or as required by the Contract: Table 3301.2-1 AASHTO Specifications Per Bar Type Reinforcement Bars AASHTO Specification Requirement Billet steel bars AASHTO M 31 “Standard Specification for Deformed and Plain Carbon and Low-Alloy Steel Bars for Concrete Reinforcement” Rail steel bars AASHTO M 322M/ M 322 Standard Specification for Rail-Steel and Axle-Steel Deformed Bars for Concrete Reinforcement Axle steel bars AASHTO M 322 M/ M 322
If the Plans or Specifications do not specify the type or grade of reinforcement bars, provide Grade 60 of any type except as modified by the following:
precast units, box Culverts, and retaining walls.
Structures.
ASTM A706, Standard Specification for Deformed and Plain Low-Alloy Steel Bars for Concrete Reinforcement, and having a yield point of at least 60,000 psi.
If required in the Plans, provide epoxy coated reinforcement bars meeting the requirements of ASTM A775, Standard Specification for Epoxy-Coated Steel Reinforcing Bars. Apply the coating in a fusion bonded epoxy coating plant certified by the CRSI. Fabricate epoxy coated reinforcement bars in plants participating in the CRSI Epoxy Coated Fabrication Certification Program and listed on CRSI’s website. Epoxy coated dowel bar and r einforcing to be used in concrete pavement is exempt from this fabrication requirement. If epoxy coated reinforcing is supplied from a coater or fabricator that does not have regular inspection by Department, the cost of providing inspection at the coater or fabricator will be withheld from monies paid to the Contractor. Ensure the plant’s Quality Control office maintains documentation required by CRSI certification, including test data and measurements taken at times and locations as directed by the Materials Engineer. Fabricate, store, and place reinforcement in accordance 2472, “Metal Reinforcement.”
3301.3SAMPLING AND TESTING
Sample and test reinforcement bars in accordance with the Schedule of Materials Control. If the Materials Engineer determines that the fusion bonded epoxy coating plant is not following approved coating procedures, correct the process and repair or replace the unacceptable Material as directed by the Materials Engineer.
