#### H2b. Prestressed Panels (Notes for Bridge Standard Drawings)

H2b1. Notes for both Concrete and Steel Spans

(H2b1.1)

Concrete for prestressed panels shall be Class A-1 with f'c = 6,000 psi, f'ci = 4,000 psi.

(H2b1.2)

The top surface of all panels shall receive a scored finish with a depth of scoring of 1/8" perpendicular to the prestressing strands in the panels.

(H2b1.3)

Prestressing tendons shall be high-tensile strength uncoated seven-wire, low-relaxation strands for prestressed concrete in accordance with AASHTO M 203 Grade 270, with nominal diameter of strand = 3/8" and nominal area = 0.085 sq. in. and minimum ultimate strength = 22.95 kips (270 ksi). Larger strands may be used with the same spacing and initial tension.

(H2b1.4)

Initial prestressing force = 17.2 kips/strand.

(H2b1.5)

The method and sequence of releasing the strands shall be shown on the shop drawings.

(H2b1.6)

Suitable anchorage devices for lifting panels may be cast in panels, provided the devices are shown on the shop drawings and approved by the engineer. Panel lengths shall be determined by the contractor and shown on the shop drawings.

(H2b1.7)

When squared end panels are used at skewed bents, the skewed portion shall be cast full depth. No separate payment will be made for additional concrete and reinforcing required.

(H2b1.8) References the P3 bars shown in the Plans of Panels.

Use #3-P3 bars if panel is skewed 45° or greater.

(H2b1.9)

All reinforcement other than prestressing strands shall be epoxy coated.

(H2b1.10) References the panel extension into the diaphragms shown in the Plan of Panels Placement.

End panels shall be dimensioned 1/2" min. to 1 1/2" max. from the inside face of diaphragm.

(H2b1.11) References the S-bars shown in the Plan of Panels Placement.

S-bars shown are bottom steel in slab between panels and used with squared and truncated end panels only.

(H2b1.12)

Cost of S-bars will be considered completely covered by the contract unit price for the slab.

(H2b1.13)

S-bars are not listed in the bill of reinforcing.

(H2b1.14) Place as fifth note under Joint Filler heading in the General Notes.

Joint filler shall be glued to the girder beam. When thickness exceeds 1 1/2 inches, the joint filler shall be glued top and bottom. The glue used shall be the type recommended by the joint filler manufacturer.

(H2b1.15)

Precast panels may be in contact with stirrup reinforcing in diaphragms.

(H2b1.16) References the transverse S-bars extension into integral end bents shown in the Plan of Panels Placement.

Extend S-Bars 18 inches beyond the front face of end bents and int. bents for squared and truncated end panels only.

(H2b1.17) References the 3/8-inch diameter strands shown in the Plans of Panels.

Any strand 2'-0" or shorter shall have a #4 reinforcing bar on each side of it, centered between strands. Strands 2'-0" or shorter may then be debonded at the fabricator's option.

(H2b1.18)

Support from diaphragm forms is required under the optional skewed end until cast-in-place concrete has reached 3,000 psi compressive strength.

(H2b1.19) Place under the Bending Diagram for U1 Bar.

U1 Bars may be oriented at right angles to location and spacing shown. U1 Bars shall be placed between P1 Bars.

(H2b1.20) Place as last note under Joint Filler heading in the General Notes.

Edges of panels shall be uniformly seated on the joint filler before slab reinforcement is placed.

(H2b1.21)

Prestressed panels shall be brought to saturated surface-dry (SSD) condition just prior to the deck pour. There shall be no free standing water on the pa
