52-1.04 PAYMENT
The payment quantity of bar reinforcing steel is the calculated weight of the reinforcing bars and wire.
The payment quantity of bar reinforcing steel includes the lap of bars for lap splicing, including locations where you use a continuous bar instead of the splice shown.
The payment quantities are based on the following:

NOTE: Bar numbers approximate the number of eighths of an inch included in the nominal diameter of the bars. The nominal diameter of a deformed bar is equal to the diameter of a plain round bar having the same weight per linear foot as the deformed bar.

The cross sectional area of reinforcing wire, in hundredths of square inches, is equal to its W-size number. The density of reinforcing wire is 0.2833 lb/cu in.
The payment quantity of welded wire reinforcement is determined based on the measured area covered by the reinforcement and does not include laps.
The payment quantity for bar reinforcing steel (bridge) includes diaphragm dowels and bolts in PC concrete members.
If alternative transverse deck reinforcement placement details are shown, the payment quantities are based on the detail that shows truss bars.
Bar reinforcing steel involved in bridge work is paid for as bar reinforcing steel (bridge) or bar reinforcing steel (epoxy coated)(bridge) unless it is included in a separate bid item.
52-2 EPOXY-COATED REINFORCEMENT AND EPOXY-COATED PREFABRICATED REINFORCEMENT
52-2.01 GENERAL 52-2.01A General 52-2.01A(1) Summary
Section 52-2.01 includes general specifications for fabricating and placing epoxy-coated reinforcement and epoxy-coated prefabricated reinforcement.
The substitution of welded wire reinforcement for bar reinforcement specified in 52-1.02B is not allowed for epoxy-coated bar reinforcement or epoxy-coated prefabricated bar reinforcement.

Submit a test sample from each batch of epoxy powder to be used for epoxy coating reinforcement to METS.
Each test sample must be:
1. Weighed to 4 ounces
2. Packaged in an airtight container
3. Identified with the manufacturer's name and batch number
Submit a test sample, from each batch of patching material to be used to repair epoxy coating on reinforcement, to METS.
Each test sample must be:
1. Weighed to 4 ounces
2. Packaged in an airtight container
3. Identified with the manufacturer's name and batch number
52-2.01A(3)(b)(iv) Test Samples
Submit test samples of epoxy-coated reinforcement and epoxy-coated prefabricated reinforcement to METS.

52-2.01B Materials
Except for field welding of butt splices, complete welding of the reinforcement before epoxy coating.
If a part of a bar or wire is described to be epoxy coated, coat the entire bar unless the bar or wire is spliced outside the limits of epoxy coating, in which case epoxy coating is not required on the part of the bar or wire beyond the splice.
Do not store reinforcement within 1,000 feet of ocean or tidal water for more than 2 months.
Patching material and the patching process must be suitable for field application.
The following must be on the Authorized Material List for fusion bonded epoxy powders and corrosion protection coverings:
1. Epoxy powder
2. Corrosion protection covering for splices
52-2.01C Construction
Except for lap splices, cover splices of reinforcement with a corrosion protection covering. Install covering under the manufacturer’s instructions.
52-2.01D Payment
The weight of epoxy coating is not included in the weight of reinforcement.
Bar or wire reinforcement extending beyond the limits for epoxy-coated reinforcement shown is paid for as bar reinforcing steel (bridge).
