for Highway Construction Page 429 of 71 5 SECTION 566 – COMPRESSION SEAL EXPANSION JOINT
566.01 Description.
Provide and install neoprene seals as specified. Prepare all surfaces in contact with new neoprene seals.
566.02 Materials.
Provide neoprene seals and adhesive as specified or an approved equal and as specified in 704.04.
566.03 Construction Requirements.
Before installing joint seal, clean joints of asphalt filler, old expansion materials/devices, bituminous material, dirt, grease, and other deleterious material. Clean joints over the total area of the blockout or opening to receive the seal. During cleaning operations, prevent debris, cleaning materials, and solutions from entering waterways. Ensure the joints are sound, clean, dry, and frost free. Submit compression seal expansion joint opening size dimensions and temperature at the time of measurement to the Engineer for approval before ordering materials. All components and materials will be in accordance with the manufacturer’s written instructions and Engineer approved. Each neoprene seal will be one continuous piece between face of curbs and installed as specified and in accordance with the manufacturer’s written instructions. Sandblast clean expansion joint surfaces immediately before seal installation.
566.04 Method of Measurement.
The Engineer will measure acceptably completed work as follows:
1.Compression seal expansion joint by the foot.
2.If the required size of the joint seal differs from plan, additional materials will be measured by the contingency amount (force account ) (109.03.C.5) .
566.05 Basis of Payment .
The Department will pay for accepted quantities at the contract unit price as follows: Pay Item Pay Unit Compression Seal Expansion Joint Materials (Per plan)………………………….….FT Compression Seal Expansion Joint Materials (Different from plan)………………….CA for Highway Construction Page 430 of 71 5 SECTION 567 – STRIP SEA L EXPANSION JOINT
567.01 Description.
Provide and install a strip seal expansion joint with the movement ratings specified.
567.02 Materials.
A.Metal. Provide extruded steel sections and anchorage gusset plates fabricated from structural steel that meets AASHTO M 27 0, Grade 36 or other approved steel used in a system. Provide steel reinforcing bars used in anchorage that meets AASHTO M 31, Grade 60.
B.Neoprene Seals. Provide preformed neoprene extrusions fabricated from polychloroprene (neoprene) that is resistant to heat, oil, jet fuel, ozone, and UV rays and meets ASTM D5973. Provide a 1- piece seal full length of the expansion joint.
C.Adhesive. Provide lubricating, elastic adhesive for installing the neoprene seals in the steel extrusions that meets the requirements of ASTM D4070 or in accordance with approved manufacturer's written specificati ons.
567.03 Construction Requirements.
A.Working Drawings. Submit working drawings as specified in 504.01.F.
B.Installation. Install the expansion joint as specified, approved shop drawings, and manufacturer’s written instructions. Supply special tools or materials required for the joint installation. The expansion joint manufacturer must have a qualified technical service representative on the project site to supervise the installation, review the supporting steel details, and inspect the interface surfaces. Ensure welding meets current AASHTO specifications and 504. Deliver and install the neoprene extrusi ons as continuous elements along the full length of the joint. Ensure shop- welded splices in steel extrusions are as specified on the shop drawings . The Engineer will only allo w field splices in steel extrusions at locations specified. Thoroughly clean the metal surfaces in direct contact with the neoprene seal and concrete to provide a high- strength bond between the mating steel surfaces with the neoprene seal and concrete. Properly position and attach the joint assembly to the structure before placing concrete in the adjacent deck or back wall. Provide for smooth ride when positioning the deck joint. Ensure the steel joint extrusions on each side of the joint are straight, parallel, and in proper vertical alignment. If the joint extrusions are not properly aligned, adjust or replace at no additional cost to the Department. Cover bridge deck joints with protective material after installation until final cleanup of the bridge deck.
