About this file
This document is a Material Specification document from the South Carolina Department of Transportation (SCDOT) detailing requirements for furnishing wire, sealant, and materials for detector loops. The specification provides comprehensive technical requirements for loop wire (No. 14 AWG, 19 Strands, single-conductor bare copper wire), sealant for traffic loop embedding, waterproofing splice materials, underwater splicing kits, wire crimps, and soldering techniques. The wire is to be furnished in 5000' reels and will be measured by linear feet, with payment made at the contract unit price for "FURNISH NO. 14 COPPER WIRE, 1-CONDUCTOR FOR LOOP WIRE".
The specification mandates that vendors provide catalog cuts and samples, and furnish any manufacturer warranties as part of normal trade practice. The loop sealant must be semi-flexible, capable of adhering to various surfaces, and resistant to environmental conditions including freeze-thaw cycling, salts, gasoline, oil, and corrosive chemicals. Acceptable sealants are listed on the SCDOT Qualified Products List (QPL). The document emphasizes specific technical requirements for splice methods, including preferred crimp techniques and alternative soldering methods, with strict guidelines on acceptable materials and installation processes.

M678.1 FURNISH WIRE, SEALANT, AND/OR MATERIALS FOR DETECTOR LOOP
1.1 Description
This specification describes requirements for furnishing Wire, Sealant, and/or Materials for a Detector Loop.
1.2 Materials
1.2.1 Loop Wire
Loop wire shall be splice-free lengths of: No. 14 AWG, 19 Strands, single-conductor bare copper wire. The conductor insulation (BLACK or GRAY) shall be high density polyethylene and shall be both ultraviolet and weather resistant. The wall thickness shall be 0.030 inch minimum point thickness. Cable shall be manufacturer in accordance with the requirements of Underwriters Laboratories, Federal specifications, and the National Electric Code.
1.2.2 Sealant
The loop sealant used to fill the saw cuts and other gaps, shall be of a type intended for traffic loop embedding. The cured sealant shall be semi-flexible, and be capable of adhering securely to concrete, asphalt, wood, metal, etc. It shall be unaffected by freeze-thaw cycling, salts, gasoline, oil, sewerage and corrosive chemicals. It shall be proportioned and mixed per the manufacturer's specifications. Acceptable sealants are listed on the SCDOT QPL.
1.2.3 Waterproofing Splice Materials
The splice at the "junction point" shall be made waterproof using the materials listed below:
a) Cable Splice Kit - Commercially available, Low-Voltage, water-proof Splice-kit; to be Plymouth
"PLYFLEX"; or 3M "SCOTCH-LOK", Unipak #3570, Resin 400, (or approved equal). To be installed per manufacturer’s instructions.
b) Heat Shrink tubes
c) Gel Caps
d) Vinyl plastic electrical tape (use where required)-Cold and weather resistant, 19 mm (3/4 inch) wide, 1.8 mm (7 mil) thickness, (Scotch 33+ or approved equal). Shall use liquid electrical coating (where required) - Fast-drying sealant compatible with vinyl tape, brush-applied (3M, Scotch coat or approved equal).
1.2.4 Underwater Splicing Kit
Where shown on the Plans, in very wet areas an Underwater Splice Kit may be required at the
"junction point". This splicing kit shall consist of a two-piece mold-body, with pourable resin sealing compound, funnels, and end sealing strips (3M, Scotch coat 82-A1 or approved equal).
1.2.5 Wire Crimps
The PREFERRED splicing method at the "junction point”, shall use a commercial/industrial grade, copper-alloy CRIMP-ON, with one end closed, of a size proper for the gauge of wires to be spliced, and

The number of conductors. It shall be installed with butt splice using a T & B type crimping tool or similar tool, intended for the purpose (NOT regular pliers). (Note: wire-nuts are not acceptable.)
1.2.6 Solder
The alternate method of splicing at the "junction point" is to use SOLDER, which shall be electronic-grade, rosin-core, 60/ lead/40 tin. Acid-core solder is not acceptable, nor are acid-type soldering pastes.
1.2.7 Certification
The Vendor shall provide details for the loop sealant, loop wire, and lead-in wire proposed.
CATALOG CUTS ARE REQUIRED
SAMPLE REQUIRED
1.2.8 Warranty
The Vendor shall furnish SCDOT with any warranties on equipment and materials that are provided by the Manufacturer or Vendor as normal trade practice.
1.3 Measurement
Wire for Detector Loops, of the size and numbers of conductors specified, shall be measured by LINEAR FEET and furnished in 5000’ reels.
1.4 Payment
Furnishing Wire for Detector Loops, measured as provided above, will be paid at the contract unit price bid for:
