West Virginia Standard Specifications for Roads & Bridges — Section 601.4

504 joint materials, and all other necessary components. Materials not conforming to this section of the specifications or from sources not listed in the contract documents shall not be used without written consent from the Engineer.

626.5.1.1 -Facing Elements: 626.5.1.1.1 -Reinforced Concrete Facing Elements: The facing elements shall be fabricated in accordance with Section 601 of the Spe cifications with the following exceptions and additions:

A.Concrete for the reinforced concrete facing elements shall attain a minimum

compressive strength of 4,000 psi at 28 days. All concrete shall have air entrainment of 7 % plus or minus 2.5 % with no o ther additives. Specified concrete properties are to be tested in accordance with applicable provision of made if the compressive strength test result is greater than or equal to, 4,000 psi. A Production Lot is defined as a group of panels that will be represented by a single compressive strength test result is greater than or equal to, 4,000 psi. A Production Lot is defined as a group of elements that will be represented by a single compressive strength sample and will consist of a single day’s production. A minimum of two cylinders shall be required for every compressive strength sample.

B.The units shall be fully supported until the concrete reaches a minimum

compressive stre ngth of 1,000 psi.

C.Unless otherwise indicated in the plans or elsewhere in the specifications, the

concrete surface for the front face shall have a Class 1 finish as define by Section

601.11and a uniform surface finish for the rear face. The rear face of the element

shall be screeded to eliminate open pockets of aggregate and surface distortions in excess of ¼ inch. The panels shall be cast on a flat area. The clevis loops, tie strip guide, or other galvanized devices shall not contact or be attached to the face element reinforcement steel.

D.The date of manufacture, the production Lot number, and the piece mark shall be

clearly scribed on an unexposed face of each element.

E.All units shall be handled, stored, and shipped in such a manner as to eliminate the

dangers of chipping, discoloration, cracks, fractures, and excessive bending stresses. Elements in storage shall be supported in firm blocking to protect the element connection devices and the exposed exterior finish.

F.All units shall be manu factured within the following tolerance:

1.Element Dimensions: Position of element connection devices within

one (1) inch, except for coil and loop embeds which shall be 3/16 inch. All other dimensions within 3/16 inch.

2.Element Squareness: Squareness as determined by the difference between the

two diagonals shall not exceed ½ inch.

3.Element Surface Finish: Surface defects on smooth formed surfaces measured

over a length of five ( 5) feet shall not exceed ¼ inch. Surface defects on the texture d-finished surfaces measured over a length of five ( 5) feet shall not exceed 5/16 inch.
