705-14 Longitudinal Joint Ties
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 4 GENERAL. LJTs are either one-piece deformed bar reinforcement or multiple-piece systems consisting of deformed bar reinforcement with 1 or 2 threaded ends and a coupler. For longitudinal joints between lanes placed simultaneously, one-piece LJTs must be supported by an assembly that secures them in position when the assembly is affixed to the underlying pavement layer. For longitudinal joints between lanes placed separately, the LJTs are either: • Loose, one-piece, deformed bars drilled and anchored into the vertical placement edge. • Loose, multiple-piece systems. In the latter case, the first piece is bolted to the paving forms in the initial concrete placement and the second piece threaded into the first piece after form removal from the initial placement. Refer to Section 502, PCC Pavement, to identify which method is used. All LJTs not referenced on the Department’s Approved List entitled “Longitudinal Joint Ties (705-14),” under “Joint Materials, Pavement,” will be subject to approval testing before their use is allowed on Department contracts. Submit approval applications to the Director, Materials Bureau, at least 120 days before their intended use. Approved LJTs and their support assemblies will be placed on the Approved List and referenced by the drawing number and approval date. Any change to a previously approved LJT requires approval by the Director, Materials Bureau, before its use. In case of conflict between the requirements of this specification and specifications referenced herein, the requirements of this specification or the instructions of the Director, Materials Bureau, will apply. The Department may perform supplementary sampling and testing of the LJTs that arrive at Department contracts. MATERIAL REQUIREMENTS

Use multiple-piece LJTs having lengths of 36 inches between travel lanes placed separately and 20 inches between a travel lane and a PCC shoulder placed separately. The length of a multiple-piece LJT includes only the deformed bar segment lengths, not the thread lengths nor the coupling length. When assembled, the coupler must cover all threads in the threaded ends.

Apply the epoxy coating in accordance with “Coating Application” in §709-04, Epoxy Coated Bar Reinforcement, by an epoxy coating applicator appearing on one of the following Approved Lists under “Reinforcing, Epoxy and Coating:” • Applicators for Steel Reinforcing Bars (709-04). • Epoxy Coatings for Longitudinal Joint Ties (705-14). • Epoxy Coatings for Dowel Bars for Transverse Joint Supports (705-15). Coatings must be continuous over the length of the LTD and 10 - 18 mils thick, except for the cross-sectional ends, which may be uncoated. Field repair of damaged coatings is not allowed. Plant or facility repairs are not allowed unless the damage results from welding or mechanical fixation to the support assembly and is within 1 inch of the weld or fixation point. Such damage must be repaired before visible rust occurs. Use a patching material supplied by the epoxy coating manufacturer that is compatible with the epoxy coating and inert in concrete. Apply the patching material to the damaged area only. Dipping the LTD into the patching material, or liberally coating undamaged areas, is not allowed. Supports containing LTDs with perforated, cracked, otherwise damaged, or improperly applied coatings will be rejected. Completely coat each dowel with a bond breaker applied at the epoxy coating applicator facility or the joint support assembly facility. The bond breaker is subject to approval by the Materials Bureau. Do not apply a bond breaker to deformed bar reinforcement.
D.Premolded Resilient Joint Filler (§705-07). Use 3/8 - 5/8 inch thick filler in transverse expansion joint assemblies only.
E.Joint Support Assemblies. Support LTDs in assemblies or “baskets” that securely hold them in position as detailed in Geometric Requirements below. Fabricate the assemblies using steel wire as depicted in the approved Materials Details. Affix 1 end of each LTD to the assembly by welding or

Vertically support the filler at the longitudinal midpoints of the dowels and perpendicular to the longitudinal axes of the dowels. Depict support mechanisms in the Materials Details. Do not weld the dowels to filler supports. Place plastic expansion caps on the free ends of the dowels (the ends opposite the fixed ends). Use expansion caps with essentially the same inner diameter as the outer diameter of the dowel plus coating thickness (+ 40 mils).

SCOPE. Requirements for the 3 common types of masonry mortar (N, S and M - increasing in strength, respectively). Use these mortars to bind masonry units together to construct masonry structures, repair masonry structures (tuck pointing), or bed and bond masonry or concrete units together. For historic masonry structures made with soft hydrated lime mortars, use a specially designed lime mortar as shown in the Contract Documents or as approved by the Engineer.

Discard all unused mortar 2 1/2 hours after initial mixing. Mortar that has stiffened may be re-tempered up to 2 1/2 hours after initial mixing by adding water to restore the original workable consistency. Use a uniform layer of mortar, 1/4 to 3/4 inch thick, for joints between uniform masonry units. For a tuck pointing (raking out and repointing) mortar, add the minimum water to the dry ingredients to produce a mortar that retains its form when hand squeezed and released. Allow this mortar to stand covered (prehydrate) for 1 to 1 1/2 hours to greatly reduce shrinkage. Then mix with sufficient water to produce a stiff, but workable consistency, and use within 2 1/2 hours of initial mixing. Avoid re-tempering the mortar when tuck pointing, matching a color, or to avoid color variations between batches (mix smaller quantities, if needed). No admixtures, except for mortar coloring agents made from light-fast, durable, alkali-resistant minerals, will be permitted without written permission of the Director, Materials Bureau. If colored mortar is specified, submit samples of hardened mortar to the Engineer. Upon approval, use the same, uniform, mortar color throughout the work. BASIS OF ACCEPTANCE. Inspection and approval by the Engineer.
