SECTION 817 CHAIN LINK FENCING MATERIALS
817.01 DESCRIPTION. This section covers materials for use in the construction of
fences of chain link fabric. The Department will allow 3 optional types of fabric; zinc- coated steel, aluminum-coated steel, or al uminum alloy (Type I, II, or III fabric, respectively). Use vinyl coated fabric (Type IV) only when specified in the Contract.
817.02 REQUIREMENTS. Conform to AASHTO M 181 for all materials except steel
posts and barbed wire.
817.02.01 Fabric. Use 0.148-inch nominal diameter wire woven in 2-inch mesh. Coat
Type I fabric to conform to Class D. Furnish fabric for fences 4 feet and 6 feet high that has the top selvages knuckled and bottom selvage knuckled or twisted and barbed. Furnish fabric for fences 8 feet high or higher with both top and bottom selvages twisted and barbed.
817.02.02 Barbed Wire. Conform to Subsection 816.04.
817.02.03 Post Caps and Socket Type Brace Connections. Use galvanized
malleable iron, or other approved type, design ed to exclude moisture from inside posts and rails.
817.02.04 Posts, Rails, Gate Frames and Expansion Sleeves. With zinc-coated steel
fabric or with aluminum-coated steel fabric, use either zinc-coated steel or zinc-acrylic coated steel. With aluminum alloy fabric, use aluminum alloy. Furnish steel posts that comply with Subsection 816.07.01.
817.02.05 Fabric Ties. Use either a minimum 0.148-inch nominal diameter aluminum
alloy or 0.120-inch nominal diameter galvanized steel.
817.02.06 Hog Rings and Tension Wire. With zinc-coated steel fabric or with
aluminum-coated steel fabric use zinc-coated steel wire or aluminum-coated steel wire. Ensure that steel ties and wire conform to ASTM F 626, except that the minimum weight of coating is 0.6 ounces per square foot. With aluminum alloy fabric, use aluminum alloy wire.
817.02.07 Miscellaneous Fittings and Hardware. With zinc-coated steel fabric or
with aluminum-coated steel fabric use zinc-coa ted steel. With aluminum alloy fabric, use aluminum alloy. 817-1 SECTION 818 WOOD PRODUCTS
818.01 INSPECTION, TESTING, AND ACCEPTANCE. The Engineer will visually
inspect and approve all treated wood products before use on the project. The Division of Materials will grade inspect, sample, and test all treated wood products before their use on the project if the plant producing the wood materials is located within the Commonwealth or a 100-mile driving distance of its borders. When obtaining treated wood materials from a plant outside this 100-mile distance, have an independent treated-wood testing company approved by the Division of Materials grade inspect, sample, and test the wood treated material at no expense to the Department. Obtain a report prepared by the independent testing firm that grade inspected, sampled and tested the treated wood material, and submit it to the Division of Materials at least 15 days before using the wood materials on the project. Use only treated wood that has been cut to size before treating. Treat field sawn surfaces according to AWPA M4.
818.02 BOARDS. Boards are defined as being less than 2-inch in nominal thickness and
one inch or more in width. Only use boards th at are one of the available grades established by either the Southern Pine Inspection Bureau (SPIB) or the West Coast Lumber Inspection Bureau (WCLIB). The Contract will designa te the grade and applicable inspection bureau.
818.03 DIMENSION LUMBER. Dimension lumber is limited to surfaced softwood
lumber of nominal thickness from 2-inch through 4-inch. Only use dimension lumber for framing members such as joists, planks, rafters, studs, and small timbers. Use only dimension lumber boards that are one of the available grades established by either the SPIB or the WCLIB. The Contra ct will designate the grade and applicable inspection bureau.
818.04 TIMBERS, 5-INCH BY 5-INCH AND LARGER. Use only timbers that are of
one of the available grades established by e ither the SPIB or the WCLIB. The Contract shall designate the dimensions, grade, species, and applicable inspection bureau.
818.05 STRUCTURAL LUMBER. Conform to the AASHTO Standard Specifications
for Highway Bridges.
818.06 Bridge Planking and Rough Local Hardwoods.
818.06.01 Species. Use only bridge planking that is White Oak, Red Oak, or Southern
Yellow Pine. The term “White Oak” includes White Oak, Chestnut Oak, Post Oak, Burr Oak, Swamp Chestnut Oak, Swamp White Oak, Live Oak, Chinquapin Oak, and other less known varieties of oak of this character. The term “Red Oak” includes Red Oak, Black Oak, Southern Red Oak, Willow Oak, Water Oak, Pin Oak, Cherrybark, or Swamp Red Oak, and other less known varieties of oak of this character. Southern Yellow Pine may be any species except Field or Loblolly.
818.06.02 Quality of White Oak or Red Oak. The Engineer will not approve wood
for use that has splits, rot, or unsound knots. Use only pieces that are sawed full to specified sizes and lengths, with square edges except wane (bark or the lack of wood) as follows. The Engineer will allow wane on one corner on 30 percent of the pieces in any shipment, not to exceed 15 percent of the width of the face on whic h it appears. The Engineer will allow this grade with sound stains, scattered worm holes or grub holes not materially affecting the strength of the piece and sound bird pecks, or their equivalent; sound knots or their equivalent not exceeding in diameter 25 percent the width of the face in which they appear. Use only boxed heartcenter wood products. Cut pieces not large enough to box the 818-1
