82-5.02 MATERIALS82-5.02A GeneralA marker must be on the Authorized Material List for signing and delineation materials. 82-5.02B Wood PostsA wood post must comply with section 82-3.02C. 82-5.02C Metal PostsSteel for a metal post must comply with ASTM A36/A36M. A metal post must be galvanized under section 75-1.02B. 82-5.02D Flexible PostsA flexible post must be white except where shown as yellow. The flexible post must be free from burns, discoloration, contamination, and other objectionable marks or defects that affect appearance or serviceability. 82-5.02E Target PlatesA target plate for a Type K-1 (CA) or a Type K-2 (CA) object marker must be the same color and material as the flexible post. A target plate for highway post marker or Type L-1 (CA) or Type L-2 (CA) object marker installed on a metal post must be manufactured from an aluminum sheet or zinc-coated steel sheet. Galvanize steel sheets under section 75-1.02B. Zinc-coated steel sheets must comply with ASTM A653/A653M, Commercial Steel, Types A, B, and C. The nominal thickness of a zinc-coated steel sheet must be at least 0.038 inch. Prepare zinc-coated surfaces to produce optimum adherence of the enamel coating without damaging or removing the zinc coating. An aluminum target plate must be aluminum alloy 3003-H14. You may use other alloys having equivalent properties if authorized. The nominal thickness of an aluminum sheet must be at least 0.050 inch. Prepare the aluminum sheets for the enamel coating by a suitable cleaning method to remove contaminants and by uniformly applying an acid-chromate-fluoride, acid-chromate-fluoride phosphate, or equivalent chemical anticorrosion conversion coating. Cut the target plate to size and shape and punch the mounting bolt holes. The surfaces and edges of the plate must be free from fabrication defects. Coat the pretreated metal target plate with an opaque white coating on both sides using a 1-coat or 2-coat system. When tested under California Test 671, the dry film for the: 1. 1-coat system must be uniform and have an average thickness of at least 0.75 mil with no individual measurement less than 0.65 mil 2. 2-coat system must consist of 0.10- to 0.20-mil-thick primer and have an average thickness of at least 0.75 mil, including primer and top coat, with no individual measurement less than 0.65 mil If using a 1-coat painting system, fabricate a zinc-coated steel target plate, including shearing, cutting, and punching, before starting the enameling process. The enamel coating on a metal target plate must be the product of a commercial manufacturer. Apply the enamel coating by spray, dip, roller, or continuous roller coating. You may use other methods if authorized. The coating must be smooth and substantially free from flow lines, paint washout, streaks, blisters, and other defects that might impair serviceability or detract from the general appearance. A finished metal target plate must not have dents or defects. The maximum edge-to-edge surface deviation from a horizontal plane must not exceed 1/8 inch. 82-5.02F ReflectorsA reflector for a marker must be made of a Type III or higher grade retroreflective sign sheeting shown on the Authorized Material List for signing and delineation materials. 82-5.02G HardwareUse (1) 1/4-inch galvanized steel or aluminum nuts and bolts or (2) 3/16-inch blind aluminum rivets and washers to attach a target plate to a post. Use 5/16-inch galvanized steel bolts, nuts, and washers to attach a marker panel to a post. 82-5.02H Highway Post MarkersA highway post marker is shown in the Bid Item List as a milepost marker. Letters and numerals on a highway post marker must be made with opaque black paint or film. The paint and film must have an equivalent outdoor weatherability as the retroreflective sheeting specified in ASTM D4956. Nonreflective, opaque, black film must be vinyl or acrylic material. Film for letters and numerals must be computer cut and have pressure-sensitive adhesive.
82-5.03 CONSTRUCTIONDrive posts in place where soil conditions allow the driving without damage to the posts. Drill pilot holes if the ground conditions are such that the posts cannot be driven without being damaged. Install target plates and marker panels after the posts are set in place. After setting the posts, fill the space around them with rock-free earth. During placement, thoroughly tamp and water the fill material such that the post is held securely in position. Unless surplus excavated material is hazardous, uniformly spread it along the adjacent roadway where designated by the Engineer. Use stencils to paint letters and numerals on highway post markers. Before Contract acceptance, spot paint all exposed areas where the paint is damaged and clean all exposed areas that are soiled. 82-5.04 PAYMENTNot Used 82-6–82-8 RESERVED 82-9 EXISTING ROADSIDE SIGNS AND MARKERS 82-9.01 GENERALSection 82-9 includes specifications for performing work on existing roadside signs and markers. Work performed on existing roadside signs and markers must comply with section 15. 82-9.02 MATERIALSNot Used 82-9.03 CONSTRUCTION82-9.03A GeneralRemove roadside signs only when replacement signs are installed or when the existing signs are no longer required for traffic. Reset or relocate each roadside sign the same day it is removed. Single sheet aluminum signs to be salvaged must be banded on a pallet with a total weight of not more than 500 lb/pallet. Reset or relocate roadside signs using existing posts. If an existing post is deteriorated or broken, notify the Engineer. If ordered, use a new post. Any new post and its installation, ordered for reasons other than damage you cause is change order work.
