blockout using an adhesive recommended by the manufacturer of the base and panel. In addition to adhesive, mount flat base to a wood timber or synthetic routed blockout with two #10 x 3/4 inch long sheet metal screws. Mount the first delineator on the beam guide rail end treatment so that the plane face of the center of the reflective area is at an angle of 0 degrees with a line that is perpendicular to the direction of traffic. Mount subsequent delineators every 81 1/4 feet (13 sections of guide rail) along tangent mainline roadway, or every 43 3/4 feet (7 sections of guide rail) along curved mainline roadway with a radius of less than 1,910 feet. If a parabolic flare in the beam guide rail exists, place the second delineator at the end of the flared section with subsequent delineators spaced as stated above. If the distance between the last delineator and the end of the beam guide rail is greater than 40 feet on tangent mainline roadways, or 20 feet on curved mainline roadways, mount a delineator on the last post or end treatment. Repair damage to the galvanized coating according to ASTM A 780. 303 609.03.03 Terminals and Anchorages At least 10 days before beginning the work, submit the manufacturer's recommendations the RE. Install terminals and anchorages according to the manufacturer's recommendations. Excavate for post holes as specified in 202.03.03. Backfill and compact using the directed method as specified in 203,03.02.B.3. Excavate cut slope as specified in 202.03.03 within the limits of the buried guide rail terminal. Drive beam guide rail posts for buried guide rail terminal to the required position. Ensure that posts are driven plumb, properly spaced, and to the line and grade shown. Attach the beam guide rail element to the spacer at every post. Attach the beam guide rail element and plate to the terminal posts. Align the top edge of the beam guide rail element in a straight line. Where a vertical transition is required, ensure that the top edge of the beam guide rail element forms the chords of a smooth vertical curve. Backfill with excavated material as specified in 203.03.02.B.3. 609.03.04 Beam Guide Rail Blockouts Where required, attach blockout on existing beam guide rail between the steel posts and rail elements. Where beam guide rail is attached to a structure, attach the blockout to the structure. Reset beam guide rail, as

attach blockout on existing beam guide rail between the steel posts and rail elements. Where beam guide rail is attached to a structure, attach the blockout to the structure. Reset beam guide rail, as specified in 609.03.05, to provide a smooth transition to the existing structure. 609.03.06 Removal of Bear: Guide Rail After removing beam guide rail, backfill the post holes and compact the area to the elevation of the adjacent surface. Dispose of beam guide rail as specified in 201.03.01.H. 609.03.08 Beam Guide Rail on Bridge A. Beam Guide Rail and Thrie Beam Guide Rail Attachment to Sidewalk Install beam guide rail consisting of steel double rail elements, steel blockouts, and steel posts welded to a base plate and mounted on bridge structure sidewalk, safety walk, or roadway sidewalk utilizing epoxy-grouted anchors approved by the Department. Install the required attachments as shown on the Plans. Core drill the holes in the bridge structure sidewalk for anchor bolts with a core drill bit. Ensure core drill bit sizes for anchor bolt holes conform to manufacture's recommendations. Space holes and locate to clear existing deck reinforcement, deck joints, conduits, and junction boxes. Fasten anchor bolts to the concrete according to the manufacturer's recommendations. 304 Ensure concrete and existing utility conduits are not damaged during the drilling for anchor bolts. Repair damage to the existing concrete caused by construction operations at no additional compensation. Furnish Certification as specified in 106.07 that the 7/8 inch diameter anchor bolt has a minimum pullout strength of 24 kips. 40
