82-3.03 CONSTRUCTION82-3.03A GeneralYou may cut the ends of wood posts at the job site. If cutting or boring is performed after treating posts with preservative, manually apply preservative to the cuts and holes under section 57-2.01B(3). Treat wood block spacers inserted between the post and sign panel on single-post installations with wood preservative under section 57-2.01B(3). If you do not immediately use laminated wood box posts, neatly stack them on dunnage. Do not paint wood posts and block spacers unless described otherwise. Drill 2 holes in each wood post to provide the breakaway feature shown. Make breakaway saw cuts and holes for the saw cuts in laminated wood box posts after installation of the posts. Do not splice the posts. You may make 1 trim cut at the bottom of the post. The line between the center of the top of a post and the center of the post at ground level must not deviate from a plumb line by more than 0.02 foot in 10 feet. Backfill the space around wood posts with earth or sand that is free of rocks or other deleterious material. Backfill around laminated wood box posts with granular material. Place the backfill material in layers approximately 1/3 foot thick. Moisten and thoroughly compact each layer. Backfill the space around metal posts with minor concrete that contains at least 470 pounds of cementitious material per cubic yard. Unless surplus excavated material is hazardous, uniformly spread it along the adjacent roadway where designated by the Engineer. 82-3.03B Sign Panel InstallationInstall lag screws by turning the lag screw into pilot holes using a wrench. Bore the pilot holes with a bit diameter equal to the root diameter of the lag screw thread. Apply PVC tape, polyethylene tape, or other authorized corrosion-resistant barrier to the areas on metal sign surfaces or hardware that will be in contact with treated wood. Before inserting bolts, fill the bolt holes with the hardware manufacturer's recommended corrosion-protection grease that will not melt or run at a temperature of 150 degrees F. The corrosion-resistant barrier and grease is not required if wood posts and blocks are treated with pentachlorophenol in hydrocarbon solvent. 82-3.04 PAYMENTAn installed roadside sign consisting of one or more sign panels attached to: 1. 1 post is 1 measurement unit of roadside sign - one post 2. 2 posts is 1 measurement unit of roadside sign - two post 3. 1 or 2 laminated wood box posts is 1 measurement unit of install roadside sign (laminated wood box post) The payment quantity for metal (rail mounted sign) and metal (barrier mounted sign) is determined by the scale weight of the pipe posts, base plates, anchorage assemblies, and other metal parts used to mount a roadside sign on a barrier or railing. The payment quantity for roadside signs installed by the strap and saddle bracket method on electroliers, sign structure posts, and traffic signal standards and by the mast arm hanger method on traffic signal mast arms is the quantity of the sign panels on these elements. Payment for furnishing sign panels is not included in the payment for roadside signs.
82-4.01 GENERALSection 82-4 includes specifications for installing sign overlays. 82-4.02 MATERIALSSign overlay materials must comply with section 82-2.02. A self-plugging blind rivet for installing a sign overlay must have a 3/16-by-5/8-inch shank. 82-4.03 CONSTRUCTIONDrill the rivet holes with a no. 10 drill bit. If the overlay is not prepunched, the maximum rivet spacing is 16 inches. If the existing sign panel is porcelain-enameled steel, drill the rivet holes with a diamond bit. Cover the exposed metal around the hole with a thin coat of silicone adhesive. 82-4.04 PAYMENTNot Used 82-5 MARKERS 82-5.01 GENERAL82-5.01A SummarySection 82-5 includes specifications for fabricating and installing markers, including highway post markers. 82-5.01B DefinitionsReserved 82-5.01C SubmittalsSubmit a certificate of compliance for: 1. Metal target plates 2. Enamel coating 3. Retroreflective sheeting 82-5.01D Quality AssuranceWhen tested under California Test 671, the enamel coating on metal target plates must have satisfactory resistance to weathering, humidity, salt spray, and chemicals. The enamel coating must have: 1. Satisfactory adherence and impact resistance 2. Pencil lead hardness of HB minimum 3. 60-degree specular gloss of 80 percent minimum 4. Excitation purity of 3 percent maximum: 4.1 As received 4.2 After 1,000 hours in an artificial weathering device as specified in ASTM G155, Table X3.1, Cycle 1 5. Daylight luminous directional reflectance, Y value, of 70 minimum The Department may sample metal target plates for testing at the production stages for the lot and sample sizes shown in the following table: Metal Target Plate Sampling
aFlat sheet stock must be identifiable with parent coil stock. The Department rejects the entire lot if either of the following occurs: 1. Any sample does not comply with section 82 2. Zinc-coated steel sheets show any evidence of damage to or removal of the zinc coating If the Department chooses to resample, the sample size may be twice the number shown in the table titled "Metal Target Plate Sampling."
