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 SECTION 832 SIGN POSTS
832.01 GENERAL. This section covers the material requirements for Type I and II sign
posts. Type I posts are perforated square steel tube (PSST) sign posts. Type II posts are U- channel sign posts. Provide posts in lengths as specified in one foot increments with a tolerance of one inch. Sign support systems shall be successfully crash tested in accordance with NCHRP Report 350 or be Manual for Assessing Sa fety Hardware (MASH) certified. Ensure that posts are straight, smooth, and free from any defects affecting their strength, durability, or appearance. Ensure th at all holes and ends are free from burrs and sharp edges and that ends are cut square.
832.02 TYPE I SIGN POSTS. Use hot rolled carbon sheet steel of structural quality that
conforms to ASTM A 1011, Grade 50 minimum. Posts shall have a minimum yield strength of 60,000 psi after cold-forming.
832.02.01 Fabrication. Fabricate the post from square tube formed of steel, rolled to
size and welded directly in the corner by high frequency resistance welding and externally scarfed to agree with corner radii. Provide the following sizes: Provide 7/16-inch diameter holes on the centerline of all 4 sides, space on one-inch centers along the entire post length beginning 1 inch from the top. Ensure holes are in true alignment and opposite each other directly and diagonally. Ensure consecutive sizes of square tubes will freely telescope for 10 feet or more of their length without the necessity of matching any particular face to any other face.
832.02.02 Finish. Conform to ASTM A 653, G90, Structural Quality, Grade 340,
Class 1. Galvanize both the interior and the exte rior of the post. Coat the corner weld with zinc after the scarifying operation. Coat the steel with a chromate conversion coating and a clear organic polymer topcoat.
832.02.03 Tolerances. The Department may reject material falling outside any of the
following tolerances:
A.Outside Dimensions. 0.010 inch. Measure at least 2 inches from the end of the tube.
B.Wall Thickness. 0.011 inch.
C.Holes. 0.016 inches in diameter.
D.Convexity and Concavity. Ensure that no sides exceed 0.01 inch. Measure in the center of the flat side relative to the corner.
E.Square. Ensure sides are 90 degrees to each other within 0.015 inch.
F.Twist. Ensure twist does not exceed 0.075 inch in any three-feet length.
G.Straight. Ensure deviation does not exceed 1/16 th of an inch in any three-feet length.
H.Corner Radii. 5/32 0.016 inch. Outside Dimensions (in.) Corner Radii (in.) Wall Thickness Gauge (in.) Weight (lb/ft) 2 by 2 5/32 12 (0.105) 2.42 2 ¼ by 2 ¼ 5/32 12 (0.105) 2.77 2 ½ by 2 ½ 5/32 12 (0.105) 3.14 832-1
