No voids shall be left under the structural steel components.
The complete portion of the deck joint assembly being water tested shall be d1805. Immediately prior to placing the concrete in the block-out, the top clamping system shall be adjusted to give the specified setting width “J” required by the stamped shop drawings.
The top surface of the bituminous mix shall be maintained smooth and level with adjacent concrete and shall not ravel.
The removal d1580 existing concrete required to prepare the block-out shall be carried out prior to the paving operation. For the first use, it is generally desirable to have the capacitance of the support as small as possible, consistent with acceptable mechanical, chemical, and heat ASTM D Edition, January 1, Adhesive on top of the seal shall be scraped off immediately. The preformed seal shall be continuous with no splices.
Adhesive shall be applied liberally to both sides of the seal and to both faces of the recess. The concrete dam shall be hand finished with a wood float.
Pecora NR, after curing, shall have a penetration, at 77 oF and grams for 5 d18850, not greater than No material other than granular shall come in contact with reinforcing steel. Some rush fees may apply.
The deck joint assemblies shall be placed after the asphalt paving operation has been completed. The preformed seal, with a lubricant and bolted components, shall be installed in conformance with the stamped installation drawings.
The new asphalt pavement shall be sawcut full depth asgm the limits of the block-out. Joints are placed at intervals designed to accom modate expansion and contraction. Deck Joint Assembly Shop Drawings: Where maintenance of traffic is necessary the joint may be tested in overlapping sections. Leakage of water through the deck joint assembly installation or the concrete-steel interfaces during this test will constitute failure of the deck joint assembly.
The method of repair shall be submitted in writing to the Contract Administrator for review prior to commencement of repair work. The method used to plug the gap shall accommodate the anticipated movement and retain the fill material in the block-out during the period of traffic maintenance. Ask for rush delivery.

After concreting, the exposed faces of the structural steel shapes shall be cleaned to remove any concrete and deleterious material. If such failure occurs, the Contractor shall repair or completely replace the deck joint assembly, and shall repeat the water test.
Ontario Provincial Standard Specifications, Construction: The deck joint assembly shall be supported on wood blocking spaced a maximum of 2 metres apart. Abrasive blast cleaned areas shall have the concrete placed in the block- out within 48 h or shall be reblasted. The grooves shall be cleaned, dried and sealed with hot poured rubberized joint sealing compound in conformance with OPSS If the previously sawcut face is undamaged and within 5 mm of the specified location, the Contractor may elect to form the groove.
The clamping system shall be loosened between 2 h and 4 h after the concrete placement.
After completion of this work the deck joint assembly shall be placed in the block-out aatm the position specified in the Contract. One set of each of the layout and installation drawings and the deck joint assembly shop drawings, marked to indicate the required changes, will be returned to the Contractor and the deck joint assembly manufacturer. The use of lubricant adhesives will not be permitted.
When the deck joint assembly is stored on site it shall be protected from dirt and deleterious materials e1850 stored so that warping cannot occur.
When the repairs are not specified in the Contract, payment for the cost of repairing existing deck joints and of repairing concrete adtm to the installation of deck joint assemblies or preformed seals will be administered under Extra Work procedures.
The dimensions of the block-out in the barrier wall shall not be greater than those of the block-out in the deck and ballast wall. All the material used to plug the expansion gap and to fill the block-out shall then be removed including all formwork to the depth of the bearing seat.
