• Relative Alignment - Locate joint openings through members within 1/2 inch of plan location. • Joint Edges - Construct all joint edges straight, parallel, and without deviation from a true line by more than 1/4 inch horizontal over the length of the joint.
• Joint Width - Construct all joint widths within 1/8 inch of planned joint width.
00585.41 588 • Deck Roadway Texturing - Do not groove within 6 inches of joint blockouts and bridge ends. For skewed Bridges, additional ungrooved portions at joint blockouts and bridge ends are allowed to accommodate the width of the gang saw.
00585.41Filled Joints - Unless otherwise specified, form Filled Joints with preformed joint filler by
placing concrete directly against the preformed joint filler material. Provide formwork behind the preformed joint filler material firm enough to prevent deflection of the joint material when placing the concrete, or place preformed joint filler against formed concrete. Unless shown or specified, place hot applied joint sealant at the top of the joint.
00585.42Closed Joints - The following requirements apply to all C losed Joints:
Closed J oint. Include the Contract number, Bridge number, joint seal M aterial, product name, and the approximate date of installation.
hazardous chemicals. Wear appropriate impermeable protective clothing when using hazardous chemicals.
according to the joint Material manufacturer's recommendations. Ensure that all joint surfaces to receive a seal are sound, dry, clean, and frost -free at the time of joint installation.
For joint replacement , remove joint material from existing joints and c lean the existing joints full depth and full width as directed by the Engineer. If existing joint surfaces have spalled, cracked, or deteriorated concrete , repair as shown or as directed to provide a uniform and smooth surface along the joint.
are suitable for joint installation according to the manufacturer's recommen dations .
joint with water. Maintain ponding of water in the Roadway Shoulders or 3 feet from the gutter line, whichever is greater, for 2 hours. Use an unnozzled water hose delivering one gallon of water per minute to the inside face of railing. Verify no leaking of joints. If leakage is observed, repair the joints using a method recommended by the manufacturer and approved by the Engineer prior to starting Work at no additional cost to the Agency. Perform additional leakage check at no additional cost to the Agency. Additional leakage checks have the same requirements.
00585.43Armored Corners - Provide joint corner armoring and anchors as shown or specified, and
according to the following:
more than 1/4 inch horizontal and 1/8 inch vertical over the l ength of the joint, nor more than 1/16 inch in either direction from a 12-foot straightedge.
Maintain a minimum Cross Sectional thickness of 1/2 inch. The steel retainer Edgebeams may be manufactured from rolled shapes and plates or may be hot -rolled steel with the gland groove milled after rolling.
transportation and installation.
00585.48 589 Fabricate steel according to Section 00560. Sandblast steel shapes just prior to installation. Use welding procedures conforming to AWS D1.1.
For new construction, install Armored Corners in preformed blockouts at least 14 Days after the deck is cast with the joint opening as shown. Support the Armored Corners securely in position before placing concrete in the joint blockout. Install the preformed seal at least 7 Days after the concrete blockouts have been cast and after the deck concrete reaches 3,000 psi.

Use either an elastomeric concrete or a structural patching product from the QPL as needed to repair the deck surface of new or existing concrete. Ensure steel bridging plates are clean, free from surface rust, oil, or other residues and contaminants when installed. Place centering pins through the holes in the steel bridging plates and down into the expansion gap to assure proper centering. Avoid placing the steel bridging plate ends under wheel rut area. Install Asphaltic Plug Joint Seals according to the manufacturer's recommendations. Place Preformed Compression Joint Seal or P oured Joint Seal in curbs and sidewalks.
00585.45Poured Joint Seal - Install Poured Joint Seals according to the manufacturer's
recommendations.
00585.46Preformed Compression Joint Seal - Install compression seals according to the
manufacturer's recommendations and the following:
• Install in one continuous strip that extends across the full Roadway width and into the curbs without splices. • Install so they remain in compression throughout the design movement range. Provide for maximum and minimum compressive pressures according to AASHTO M 297 ( ASTM D3542).
Base the compression seal nominal size on the design movement of the joint and the seal's anticipated compression set.
00585.47Strip Seal - Install Strip Seals according to the manufacturer's recommendations and the
following:
• Use steel retainers acting as the Edgebeams according to 00585.43(a). • Field weld rail segments that are too long to ship in one piece according to AWS D1.1. • Base the joint opening between E dgebeams on Structure temperature at the time of joint placement and the designed temperature movement rating. • Install seals in one continuous strip, extending across the full Roadway width and into the curbs without splices. • Remove all lubricant/adhesive from the top of the installed seal before the adhesive sets.
