Signs, Delineators, and Reference Markers

702.1DESCRIPTION

1 This section describes the requirements for providing and installing permanent roadside and overhead signs, delineators, and markers.

702.2MATERIALS

1 Provide materials in accordance with the following: Materials Subsection Bolts and Fasteners 816.8 Delineator Posts 816.5 Epoxy Mastic Paint 809.10 Galvanized Coating 815.14 High-Strength Bolts and Fasteners 815.2 Overhead Sign Supports 816.7 Retroreflectors 816.3 Roadway Sign Supports 816.6 Timber Sign Posts 816.10 Sheet Aluminum For Sign Panels 816.1 Signs and Traffic Devices 816 Structural Steel 815.1 Retroreflective Sheeting 816.4 2 For permanent signs, provide sheet aluminum 0.125 in [3 mm] thick. 3 For main load-carrying tension members at least ½ in [12 mm] thick, provide in accordance with the notch toughness requirements in Subsection 815.1, Structural Steel. 4 The department specifies dimensioned timber posts by nominal sizes and will accept American Lumber Standard dressed sizes as minimum net sizes.

702.3EQUIPMENT

1 Ensure that the concrete batch plant and mixers meet the requirements of Subsection 513.3, Equipment.

702.4CONSTRUCTION

702.

4.1Reference Markers

1 Install reference markers at the locations staked. Provide reference post panels

manufactured from aluminum 0.125 in [3 mm] thick.

702.4.2 Posts

1 Ensure that post size, drilled hole size, and vertical hole location are in accordance with the specified details for breakaway posts. Do not order posts until the engineer has checked post lengths in the field, rounding measurements as follows:

2 Backfill and compact around posts with suitable material in layers up to 6 in [150 mm] thick to set firmly. Hold driven posts in alignment during installation, and protect post tops with a cap during driving.

3 For square, tubular-steel sign posts, drive an anchor section into the ground to within 2 in [50 mm] above the surface. Extend a telescoping support post into the anchor at least 12 in [300 mm], and attach the post to the anchor with a bolt and nut.

702.4.3 Drilled Shaft Foundations

1 Construct drilled shaft foundations for sign posts to specified dimensions and in accordance with Section 506, Drilled Shaft Foundations. Securely fasten reinforcing steel and conduit, when specified, to prevent dislocation while placing concrete. Hold anchor bolts plumb and in proper alignment for a minimum of 24 hours after concrete placement is complete. Do not bend anchor bolts to straighten or to move into required position. Place concrete against undisturbed earth, unless casing is used, and cure at least 14 calendar days before sign erection. Final grade in accordance with Subsection 203.4.5, Finishing, to leave the foundation top flush with the surface.

702.4.4 Sign Panels

1 Provide sign panels free of damage or defects. When formed in multiple sections, ensure that joints are tight and smooth. Ensure that retroreflective sheeting is applied to the panels in accordance with the sheeting manufacturer’s recommendations and with adjacent strips matched for color to provide a surface free of imperfections and uniform nighttime appearance and brilliance. Ensure that the sign edges are edge-sealed in accordance with the manufacturer’s specifications for the type of sheeting applied. Schedule with the department’s Traffic Program 14 calendar days prior to installation a sign inspection at the project site for proper layout, materials, and fabrication standards for all signs. Liquidated damages in the amount $200 will be assessed for each additional inspection if all signs are not made available for inspection on the scheduled date. Inspection of signs by the department’s Traffic Program is not considered final

acceptance of the signs. The engineer will reject signs without proper inspection from the department’s Traffic Program, or that do not meet the specifications at the time of erection.

2 Install fasteners, backing strips, and other incidentals as specified. Ensure that the bolts do not protrude above the sign panel surface.

3 After erection, clean sign faces and repair marred or damaged surface coating with the same material as the original coating.

702.4.5 Removal and Resetting of Signs

1 Without damaging the sign or post, remove and stockpile existing signs to be reset.

2 Reset sign posts and sign panels as specified. Provide additional mounting hardware to reset sign panels on new or existing posts at no additional cost to the department. Replace removed posts that are too short to be reset as specified.

3 Backfill holes left by sign removal with approved material in layers 6 in [150 mm] thick. Compact each layer to at least the density of the adjacent material. Remove existing concrete foundations to at least 6 in [150 mm] below the ground surface, but remove them completely when installing a new foundation at the same location.

702.4.6 Overhead and Breakaway Signs

1 Submit shop drawings for overhead signs to the State Bridge Engineer in accordance with Section 105.2, Working Drawings.

2 After fabrication, blast-clean steel components of overhead signs in accordance with Society for Protective Coatings (SSPC)-SP 6. Paint with one coat of epoxy-mastic paint. Mix, apply, and allow paint to dry in accordance with the manufacturer’s recommendations. Ensure it has a dry film thickness of at least 5 mil [130 µm]. Do not damage painted sign surfaces during transport; repair damaged areas in the field by applying a second coat of epoxy-mastic. Instead of painting, and if suitable for the structure, components may be galvanized in accordance with Subsection 501.4.1.25, Galvanizing.

3 For breakaway sign supports, ensure fabrication in accordance with specified details and galvanization in accordance with Subsection 501.4.1.25, Galvanizing.

702.4.7 Delineators

1 Remove existing delineators and do not reuse. Layout delineator locations. Match the delineator reflector color to the adjacent edge-line stripe color. Install delineators as shown in the contract. Position delineators to face traffic and obtain the most effective retroreflection.
