6-316 SECTION 667 – OTHER TRACK MATERIAL
667.01 DESCRIPTION . This work shall consist of removing and replacing joint bar sets, installing
compromise rail joint assemblies to connect two abutting rails of differing sizes, installing conventional poly or bonded insulated joints, and removing and replacing tie plates.
667.02 MATERIALS . Materials shall meet the requirements of the following subsections:
Other Track Material (OTM) ................................ ................................ ..................... 715.0 8
667.03 SUBMITTALS . The following information shall be prepared and submitted for review and
approval by the Engineer . Submittals shall meet the requirements of Subsection 105.0 6.
a.Fabrication drawings of all track material components. For joint bars and compromise joint ba rs, the fabrication drawings shall indicate all bolt hole locations.
b.Manufacturer’s certificate of compliance for all materials that are incorporated into the work.
c.For insulated joints, the following submittals are required:
1.Catalog cuts or o ther manufacturer’s descriptive literature on insulated joints and fasteners.
2.Manufacturer’s field installation (to include bolt torque) and test procedures.
3.Locations where rail cutting and welding is required for insulated joints.
4.Fabrica tion drawings, including fabrication details, for insulated joints.
d.Shop drawings and catalog cuts for all assembly hardware for bridge tie connections.
667.04 JOINT BAR SETS . All defective joint bar sets identified by the Engineer shall be removed an d
acceptable similar replacement bar sets (assemblies) installed. If one or both joint bars are defective, both joint bars shall be replaced. Joint bars may be deemed defective and rejected by the Engineer for the following reasons:
a.Cracks, breaks, or other flaws that impair the proper functioning of the bar or where integrity of the bar has been compromised.
b.Bolt holes with wear which prevents a snug fit of the bolt assembly. 6-317 (c) Excessive deterioration from rust, scale, or brine.
d.Any vertical movement of either rail when all the bolts are tight. All existing bolts, nuts, and washers shall be replaced. All the bolts for a joint bar assembly shall have a washer and a nut and shall be tightened in accordance with AREMA Chapter 5, Section 5.5. 667.0 5 COMPROMISE JOINTS . Compromise joints shall be installed so opposite rail joints are staggered by at least 4 feet 11 inches. When joining rails of differing sizes with a compromise rail joint assembly, it shall be fitted so that the top of rail surface and the gage face of the rails to be connected are held in alignment. Bars shall be stamped with markings indicating the field side and gage side of the bars and shall be installed accordingly. The Contractor shall install bolt sets in all ass embly bolt holes. Driving of bolts will not be permitted. The Contractor shall tighten all bolts in accordance with AREMA Chapter 5, Section 5.5 . If there are fewer existing bolt holes in the rail than there are bolt holes in the compromise joint bar, the Contractor shall provide additional bolt holes by drilling with a rail drill of the appropriate size. No other method will be permitted.
667.06 Insulated Joints .
a.Inspection . Insulated joints shall be inspected for conformance with the manufacturer’s material specifications before installation of track. Insulated joints shall be inspected after installation to ensure conformance with the approved manufacturer’s field installation and test procedures.
b.Installation of Insulated Joints . Insulated join ts shall be installed in accordance with the manufacturer’s fabrication drawings, the applicable requirements of AREMA C&S Manual Part 8.6.35 , and the Plans. Insulated joints shall be installed at signal locations in track as shown on the Plans. The locat ion of insulated joints may be adjusted to match field conditions where directed by the Engineer. At each location requiring two insulated joints, the insulated joints shall have a maximum stagger in compliance with AREMA C&S Manual, Part 2.1.20A through AREMA C&S Manual, Part 2.1.20D . The Contractor shall install all insulated joints as suspended joints. In ballasted track, the Contractor shall re -space existing cross ties to achieve this requirement. 6-318 Field welding of bonded insulated joints into the run ning rail shall be in accordance with Section 662. The Contractor shall secure all insulated joints by box anchoring 200 feet of each side of an insulated joint. Bolts shall alternate so that all nutlocks are not on one side of the joint unless otherwise specified by the manufacturer.
667.07 TIE PLATES . Existing defective tie plates shall be removed and replacement tie plates installed
on the ties indicated on the Plans or where directed by the Engineer. The Contractor shall plug spikes holes, adze ties, place new tie plates, and spike new tie plates in accordance with Subsection 662.08 , Subsection 662.10(b) , and Subsection 662.11 .
667.08 METHOD OF MEASUREMENT . The quantity of Remove and Replace Joint Bar Sets to be
measured for payment will be the numbe r of joint bar sets (consisting of two joint bars, and all necessary bolts, nuts, and washers) installed in the complete and accepted work. The quantity of Compromise Joint Bar Sets to be measured for payment will be the number of compromise rail joint ba r sets (consisting of two joint bars, and all necessary bolts, nuts, and washers) assemblies installed in the complete and accepted work. The quantity of Insulated Joints to be measured for payment will be the number of insulated joints installed in the complete and accepted work. The quantity of Remove and Replace Tie Plates to be measured for payment will be the actual number of tie plates furnished and installed in the complete and accepted work.
667.09 BASIS OF PAYMENT . The accepted quantity of Remov e and Replace Joint Bar Sets will be paid
for at the Contract unit price per each joint assembly. Payment will be full compensation for removing existing joint bars; furnishing and installing new joint bars, bolts, nuts, and washers, labor; and furnishing all tools, equipment, materials, and incidentals necessary to complete the work. The accepted quantity of Compromise Joint Bar Sets will be paid for at the Contract unit price per each joint assembly. Payment will be full compensation for installing a pro perly fitted compromise rail joint assembly, complete with new properly tensioned bolts, nuts, and washers, and for furnishing all materials, labor, tools, equipment, and incidentals necessary to complete work. 6-319 The accepted quantity of Insulated Joints will be paid for at the Contract unit price per each. Payment will be full compensation for furnishing, transporting, handling, and placing the materials specified, and for furnishing all labor, tools, equipment, and incidentals necessary to complete the w ork. Plug rails for bonded insulated joints will not be paid separately but will be considered incidental to Insulated Joints. Field welding for the installation of bonded insulated joints will not be paid for separately but will be considered incidental t o Insulated Joints. The accepted quantity of Remove and Replace Tie Plates will be paid for at the Contract unit price per each. Payment will be full compensation of all labor, material, including track spikes and tie plugs, equipment, and incidentals nec essary to complete the work.
