SECTION 830 RETROREFLECTIVE MATERIALS
830.01 DESCRIPTION. This section covers the requirements for retroreflective
materials used on signs, delineators, and channelizing devices (drums, cones, barricades, and tubular markers).
830.02 GENERAL REQUIREMENTS. Ensure that all materials and prepared sign
faces are free from cracks, tear s, ridges, humps, discolorat ion, or other objectionable blemishes. Use sign sheeting materials that pr esent a finished surface suitable for receiving stenciled messages, paint overlays, or film overlays. Provide only retroreflective sign sheeting materials that conform to Federal Specification L-S-300C for solvent, heat, cold, and humidity resistance. The Department will reject signs and traffic control devices that do not conform to the requirements of this section.
830.02.01 Delineator Sheeting. Provide the size, color, and shape specified in the
Contract.
A.Barrier Wall Delineator. Use retroreflective sheeting conforming to ASTM D 4956, Type IX, Class 1.
B.Guardrail Delineator. Use retroreflective sheeting conforming to ASTM D 4956, Type IX, Class 1.
C.Delineator Post. Use retroreflective sheeting conforming to ASTM D 4956, Type IX, Class 1.
830.02.02 Barricade Sheeting. Use retroreflective sheeting conforming to ASTM D
4956, Type III or IV, Class 1.
830.02.03 Drum Sheeting. Use retroreflective sheeting conforming to ASTM D 4956,
Type III or IV, Class 1 or 3.
830.02.04 Cone and Tubular Marker Sheeting. Use retroreflective sheeting
conforming to ASTM D 4956, Type III or IV, Class 1 or 3.
830.02.05 Roll Up Sign Sheeting. Use retroreflective sheeting conforming to ASTM
D 4956, Type VI, Class 5. Use fluorescent orange sheeting for warning signs in construction zones.
830.02.06 Permanent Sign Sheeting. Use retroreflective sheeting conforming to
ASTM D 4956, Types III, IV, IX, or XI. Use th e appropriate type and color of sheeting as specified in the plans. If not addressed in the plans, use type and color in conformance with the Traffic Operations Guidance Manual.
830.02.07 Construction Sign Sheeting. For warning signs in construction zones, use
retroreflective sheeting conforming to ASTM D 4956, Types IV, VIII, IX, or XI and that is fluorescent orange in color. For regulatory and guide signs in construction zones, use retroreflective sheeting confor ming to subsection 830.02.06.
830.03 APPROVAL. The Department will approve retroreflective sheeting materials
based on KM 64-204 and conformance to this section. 830-1
830.04 FIELD PERFORMANCE. The Department will consider the retroreflective
sheeting defective if any of the following conditions are observed:
1.When viewed from a moving vehicle under normal day and night driving conditions, sheeting has deteriorated to the extent that the sign or device is ineffective for its intended purpose.
2.Sheeting no longer meets the minimum criteria for retained retroreflectivity
3.For permanent signs, the time between sign installation and the manufacture date exceeds one-year. Traffic control devices found to have defective sheeting shall be replaced at the discretion of the Engineer with no additional cost to the Department.
830.05 PACKAGING. Ensure that all materials are suitably and substantially packaged
and have the name and address of the manufact urer or vendor, contract or purchase order number, kind of material, trade name, date of manufacture, lot and run number, color, and net contents plainly marked on each package or container.
830.06 CERTIFICATION. Submit retroreflective sheeting manufacturer’s certification
stating conformance to the requirements of this section for fabricated signs, delineators, channelizing devices, or other applications of retroreflective sheeting delivered for use on projects. Clearly state the manufacturer, product name and product code as listed in the Department’s List of Approved Materials, sheeting type, sheeting color, sheeting lot number, sheeting expiration date, and quantity.
830.07 ACCEPTANCE. The Department will accept retroreflective sheeting based on
verification of inclusion on the Department’s List of Approved Materials and conformance of the manufacturer’s certification. The Department reserves the right to sample and test retroreflective sheeting, at the Engineers di scretion, in accordance with the Department’s Materials Field Sampling Manual. . 830-2 SECTION 831 — CONSTRUC TION ZONE TEMPORARY MARKING TAPES
831.01 DESCRIPTION. This section covers pavement marking material designed to
provide reflective delineation in construction zones. This section covers the following types of marking material:
A.Type A . Non-removable Pavement Marking Tape.
B.Type B. Removable Pavement Marking Tape.
831.02 General.
831.02.01 Manufacture. Use a material consisting of a weather and traffic-resistant
reflective film on a backing precoated with a pressure-sensitive adhesive.
831.02.02 Adhesive. Use a precoated pressure-sensitive adhesive that does not require
a liner or activation.
831.02.03 Application Properties. Ensure that the material adheres to asphalt and
concrete surfaces, when applied according to the manufacturer’s recommendations, at or above surface temperatures of 40 F. Ensure that the material does not require any protective devices such as traffic cones or barricades after application. Do not allow re-use of previously installed material.
831.02.04 Conformability and Thickness. Use material that is thin, flexible,
formable, and remains conformed to the texture of the pavement surface following application. Ensure that the thickness of the material furnished is within 2 mils of the thickness of the material submitted for approval. Use tape with a minimum width of 4 inches.
831.02.05 Miscellaneous Requirements. Ensure that the supplied material is of good
appearance, free from cracks, with edges true, straight, and unbroken. Make the material available in rolls with no more than 3 splices per 50 yards of length. Package the material according to accepted commercial standards. Ensure that the supplied material is capable of being stored at temperatures up to 100 F for a period of one year after purchase without adversely affecting the physical properties stated in this section.
831.03 APPROVAL. The Department will approve temporary marking tapes based on
conformance to KM 64-207 and the requirements of this section. The Department may remove temporary marking tapes from the Depa rtment’s List of Approved Materials for poor field performance in Kentucky.
831.04 CERTIFICATION. Submit manufacturer’s certification stating conformance to
the requirements of this section for each shipment of approved temporary marking tapes delivered for use on projects. Clearly stat e the manufacturer, product name, product code and color as listed in the Department’s List of Approved Materials. Identify the lot number(s), expiration date and quantity delivered.
831.05 ACCEPTANCE. The Department will accept temporary marking tapes based on
verification of inclusion on the Department’s List of Approved Materials, compliance of the manufacturer’s certification, verification the expiration date will not be exceeded, and visual inspection of the temporary marking tape installation. The Department reserves the right to sample and test temporary marking tape, at the discretion of the Engineer, in accordance with the Department’s Field Sampling and Testing Manual. 831-1
