BRIDGE JOINT SEALS
522.01 Description.
This Section shall cover the work of furnishing and installing bridge joint seals at the locations shown by the plans or directed, all in accordance with this specification and plan details. Said seals are for the purpose of preventing the passage of water and other materials through the joint. Types of bridge joint seals have been classified as follows: Compression Seals and Diaphragm Type Seals.
522.02 Materials.
Materials furnished for use under this Section shall conform to the appropriate requirements of
Division 800 — , Materials, and the plan details.
Bridge joint seals for existing bridges shall be the type of seal material shown on the plans.
522.03 Construction Requirements.
a.General . The sealing of bridge joints shall be limited to those joints noted by the plans to be sealed. The plans and proposal will designate the "total joint movement" for which a joint is to function. Shop drawings of the bridge joint seal system designated by the plans or, if allowed, selected by the Contractor from the plan designated alternates, must be approved by the B ridge Engineer. Shop drawings, etc. of the seal system shall be submitted to the Bridge Engineer for approval. After final approval of the drawings, the Contractor shall resubmit seven copies of the drawings plus one set of satisfactory reproducibles (Myla r or equal) for distribution.
b.Forming of Joint . Special attention shall be given to joint construction to insure that proper allowances for temperature, skew, etc. are made in forming the joint width. In the same manner, the anchorage system (bolts, pl ates, etc.) or joint armor shall be carefully set in the formwork to insure proper anchorage and functionability of the completed joint. All elements of the joint seal system shall be on hand before commencing forming of the joint.
c.Installation of Bridge Interior Joints . It shall be the Contractor's responsibility to insure that the joint width, alignment, etc. is in accordance with the bridge plan details and approved shop drawing. Any deviation from the plans and approved shop drawings shall be report ed and corrective remedial action taken before installing the seal element. Installation of the seal element shall be in accordance with the manufacturer's recommendation and Departmental directives. Care shall be taken to insure the proper cleaning of the joint and use of lubricants, adhesives, or combination lubricant -adhesive during the installation. Splicing of the seal elements will not be permitted in a joint system unless so noted by plan details or the approved shop drawings.
d.Installation of Bri dge End Joints . The Bridge Contractor shall install that portion of the bridge end joint anchorage system required to be installed in the bridge deck in accordance with bridge plan details and approved shop drawings. The remaining elements shall be match -marked and properly stored as directed until such time as the bridge end slab is constructed or the contract is terminated, at which time the stored elements shall be turned over to the Engineer. The Contractor constructing the bridge end slab shall have th e responsibility of incorporating that portion of the joint seal system required by the bridge plans and approved shop drawings into the bridge end slab. It shall be the Contractor's responsibility to insure that the joint width, alignment, etc. is in accordance with above noted requirements; any deviation shall be reported and corrective remedial action taken before installing the seal element. The portion of the joint seal system to be installed in the bridge end slab and the seal element will be made ava ilable to the bridge end slab Contractor along with installation details if such is not provided by the plan details. The Contractor shall have full responsibility for protection, etc. of elements of the joint seal system furnished him until the joint seal system is accepted. Any damage to the elements caused by his operations shall be corrected as directed
522.05 Basis of Payment.
without additional compensation. Installation of the seal element shall be as noted in the second paragraph of Subarticle 522.03(c).
e.Bridge Joint Se al. The Contractor shall obtain the manufacturer’s recommendations for the installation of the joint seals and shall furnish these recommendations to the Engineer prior to the installation of the seals. The seals shall be installed as directed by the Engin eer.
522.04 Method of Measurement.
a.Items 522-A, 522 -B, and 522 -C. Ordered and accepted sealed joints will be measured in linear feet {meters} along the top surface of the designated joint between the bridge gutters to the nearest 0.1 foot {millimeter}. No measurement will be made for that portion of the seal required by plan details to extend through or above the gutter line; such being considered incidental to the sealing of the joint.
b.Items 522-D and 522 -E. These items, when provided, will be meas ured as a lump sum unit for the designated bridge structure. Said measurement will cover the sealing of all the bridge joints of the type designated, interior or end, all in accordance with the plan requirements and the details noted in this Section.
c.Item 522-G. The joint seal will be measured in linear feet {meters} along the top of the installed and accepted seal.
522.05 Basis of Payment.
