1026NEOPRENE STRIP SEAL DAM

1026.1DESCRIPTION—This work is the furnishing and installation of neoprene strip seal expansion dam

for bridge joints, including the necessary fabricated structural steel extrusions and sliding plates.

1026.2MATERIAL—

The galvanization in the retainer extrusion must be of uniform thickness and free of excessive build -up, which would hinder the installation of the seal. Have the expansion dam fabricator demonstrate that the seal can be installed properly before shipment.

Bulletin 15.

1026.3CONSTRUCTION—As shown on the Standard Drawings and as follows:

Before fabrication, submit shop drawings, as specified in Section 105.02(d), showing complete details, dimensions, size, and type of seal as well as other information and data necessary for the complete fabrication and erection of the dam. Before installing the seal, clean metal surfaces in direct contact with the seal according to the manufacturer’s recommendations. Install seal with hand or air driven tools recommended by the manufacturer. Do not splice the seal, unless indicated. If splices are indicated, use only if splices are vulcanized and spliced by the manufacturer in the shop/factory and are watertight. If stretching of the seal during installation is unavoidable, do not exceed 5% elongation. The Department will not accept cocked or twisted seal installation. Remove and replace seals that are damaged during installation. Repair galvanizing damaged during construction operations as directed and according to the manufacturer’s recommendations, at no additional cost to the Department. After installation, flood seal with water and inspect for leaks and/or damage. Repair any leaks or damage as directed and according to the manufacturer’s recommendations.

1026.4MEASUREMENT AND PAYMENT—Linear Foot

For the movement specified. Measured out-to-out along the centerline of the final, in place, exposed surfaces of the seal , fabricated structural steel extrusion, and the steel sliding plates, including sidewalks if applicable, following the vertical and sloped faces of curbs and barriers, resulting in a true length, not a horizontally projected length. Non- exposed surfaces will not be included in the final, in-place measurement.
