2606. ELASTOMERIC SLAB SEAL EXPANSION JOINT 2606.1. Materials a) Steel inserts shall conform to IS: 226. Use of any other materials like fiberglass or similar material shall not be permitted. b) Elastomer for elasiomeric slab unit (ESU) shall conform to clause 915.1 of KC: S3 (Pan 11), compounded to give hardness 1RHD 60 +5, subject to the following additional stipulations: i) Chloropiene (CR) only shall be used in the manufacture of elasiomeric expansion joints. No reclaimed/natural rubber or vulcanised wastes shall be used. ii) The chloroprene material used in the manufacture of elastomeric (expansion joints) shall be Neoprene WRT. Bayprene 110, Skyprene B5 or Denka S- 40V. iii) Chloroprene content of the compound shall not be lower than 60 petcent by weight. The ash content shall not exceed 5 pr cent (»s per tests conducted in accordance with ASTM D-297 for (i) and (ii) above. iv) EPDM and other similar candidate elastomers for expansion joints shall not be permitted. c) Elasiomeric plugs, d) Spacer bars, marked with centre to centre distance of fixing holes. e) Fixing bolts and nuts made of stainless steel. f) Anchor bars comprising hooked anchor stiffeners welded with tower steel inserts and sinusoidal anchor bars welded with horizontal leg of the edge steel inserts. The elaborate anchoring arrangements of steel inserts shall be permanently welded tied with the steel reinforcement 2606.2- Fabrication a) Steel inserts shall be grit blasted and provided with epoxy paint. b) Edges of reinforcing steel sections shall be founded. c) Expansion joints shall be fully moulded to the required size in one single vulcanising operation including the encasing layers as integral and homogeneous part. d) Tolerances of fabrication shall be as follows: i) Plan dimension -> ± 5 mm ii) Total height -> ± 3 mm
2606.3. Supply and Handling i) The Contractor shall supply all steel-reinforced elasiomeric expansion joints including bolts, nuts, sealant, plugs and all other accessories for the effective installation of the joints including angled jointing sections for kerbs. ii) Expansion joint material shall he handled with care and stored under cover by the Contractor to prevent damage. Any damage occurring after delivery shall be made good at the expense of the Contractor to the satisfaction of the Engineer. 2606.4. Installation 2606.4.1. Expansion joints shall be installed as per approved drawing. Steel inserts, spacer bars, concreting of pockets, fixing of elastomer slab unit and presetting, etc., shall be done as per he following: a) Steel Inserts i) Deck casting shall be done leaving pockets or recess for steel inserts and anchors of the expansion joint as per drawing. ii) Steel inserts shall be lowered at the appropriate location inside the pocket iii) The top of the insert shall be flush with the finished level of wearing course maintaining the camber. iv) Spacer bars, duly set appropriately to the month of installation, shall be filled under proper supervision. v) Anchor rods shall be lied/welded with the existing deck main reinforcement, maintaining level and alignment. vi) Welding between anchor rods and deck reinforcement is preferable. If welding is not possible, strong steel tie wires shall be used for fastening, under proper supervision, b) Spacer Bar i) Spacer bars shall be used to ensure proper positioning of bolts and also leveling of the steel inserts during fixing of the same with the deck reinforcement and casting second stage concreting in the pocket thereafter. ii) The 2nd stage concreting operation shall preferably be started within 24 hours of fixing the steel inserts. In such cases, spacer bars should be removed just after concreting is finished. If there is a substantial time lag between fixing of inserts and concreting, then any one of the following methods shall be adopted, depending on the support condition: a) For simply supported bridge resting on simple elasiomeric bearings, (with no dowel pins), insert shall be placed in position with spacer bars at every alternate joints. Such joints shall be called restrained joints hereafier. In other words, inserts shall not be fixed simultaneously at two ends of one span. If the above condition is satisfied, inserts with spacer bars shall be kepi in position for a substantially longer period at such restrained joints. Spacer bars shall be removed after concreting of such restrained joints and inserts placed in position with spacer bars at the other unrestrained joints thereafter. b) For bridges resting on other than elasiomeric bearings (including bearings with dowel pins at one end), after placing and aligning the inserts and securing the same, the spacer bars shall be removed Concreting shall be done with great care so that inserts are not dislocated or distorted.
