A.System A
1.Membrane. Provide a membrane laminate formed with suitably plasticized coal tar and reinforced with non -woven synthetic fibers or glass fibers. The membrane shall be a uniformly well - manufactured product, free from blemishes, discontinuities, and other defects. Furnish the membrane in rolls, having a width of 30 or 48 inches or other widths as approved by the Engineer. Ensure that the membrane c onforms to the requirements specified in Table
906.04 1.
Table 906.04 -1: Requirements for Membrane (System A) Property Test Method Value Thickness - 70 ± 5 mils Pliability 180 -degree Bend over 1/4 -inch mandrel at -25 °F ASTM D146 No cracks Softening Point (minimum) ASTM D36 (R & B) 230 °F
2.Mastic. Use a cold -applied type mastic, recommended by the membrane manufacturer, that is compatible with the membrane.
B.System B
1.Membrane. Provide a laminate of rubberized asphalt, reinforced with synthe tic fibers or mesh. The membrane shall be a uniformly well-manufactured product, free from blemishes, discontinuities, and other defects. Furnish membrane in rolls having a width of 36 inches or other widths as approved by the Engineer. Ensure that the membrane conforms to the requirements specified in Table
906.04 2.
906.04 942 Table 906.04 -2: Requirements for Membrane (System B) Property Test Method Value Thickness (minimum -- 65 mils Tensile strength (minimum) ASTM D882 300 psi Elongation at Break (minimum) ASTM D882 150% Pliability 180 -degree Bend over 1/4-inch mandrel at -25 °F ASTM D146 No cracks Peel Adhesion, 7 days at 120 °F +7 days water immersion (minimum) TT-S-00230 Modified 5 psi
2.Mastic. Use a cold -applied type mastic, recommended by the membrane manufacturer, that is compatible with the membrane. Provide bridge deck sealants listed on the Department’s QPL. Prior to approval and use of the materials for bridge deck sealant, submit to th e Materials and Test Engineer a notarized certification by the formulator of these materials, stating that the materials proposed for use, or materials of identical formulation, have been tested and meet all the specified requirements. Include with this n otarized certification a certified laboratory test report, containing numerical test data of all the specified requirements, for the materials, or materials of identical formulation, proposed for use, and a sample of the proposed materials for preliminary evaluation. The approval granted based on these certifications will remain in effect until such time that the formulation is changed or the Materials and Tests Engineer requires, at its discretion, requalification of the materials for use, in which event the qualifying procedure shall be repeated. Submit a certification from the manufacturer of the materials with each subsequent shipment of materials. The certification shall identify the shipment by lot or batch number, state the quantity of material ship ped, and state that the material is identical to a lot or batch number (designate) that the Department previously qualified for use. The Department reserves the right to require samples of all materials to be submitted to the Laboratory for testing. 907.01 943 SECTIO N 907 – CONCRETE REINFORCEMENT

907.01 Bar Reinforcement for Concrete Structures
Unless otherwise specified, for all steel reinforcement for con crete, provide billet steel bars conforming to the requirements of ASTM A615, Grade 60. Use standard CRSI hook details unless otherwise shown on the Plans. Provide epoxy -coated reinforcing steel that is listed on the Department’s QPL. Package, in an airt ight container, a representative 8 -ounce sample of the coating material from each batch, identify it by batch number, and furnish to the Engineer. In addition, for repair of any damage incurred during shipment or installation, the fabricator initially sha ll furnish to the Project a repair kit containing a touch -up roller and 16 ounces of touch -up coating material with each shipment of epoxy coated reinforcing steel, with additional supplies being furnished as needed. Provide metal chairs and supports coate d with plastic, epoxy, or other approved material that is chemically and electrically inert in concrete. Provide plastic -coated tie wires for use with epoxy -coated reinforcing steel. Obtain the Engineer’s approval of such tie wires before use.
907.02 Dowel and Tie Bars
Provide plain dowel bars conforming to ASTM A36 or A615. Use paint meeting the requirements of SSPC Paint Specification No. 15, Type 1 (red oxide paint) or SSPC Paint Specification No. 25. For plast ic coated dowels, meet the coating requirements of AASHTO M 254. For epoxy coated dowels, meet the coating requirements of ASTM D3963. Provide bond breakers, of the type recommended by the coating manufacturer, for all dowel bars except for Type A coated dowels conforming to AASHTO M 254.
