1 Expansion and Contraction (Uniform Temperature) Maximum and minimum shade air temperatures have been recorded at weather stations over many years These records are used to predict the maximum and minimum design temperatures that the bridge deck may experience during its design lifeThese temperatures are presented in the codes in the form of isotherm maps.

Chapter 12 Abutments

rigid frames), the abutment wings are joined to the body by a mortised expansion joint For a non-skewed abutment, this enables the body to rotate about its base and allows for superstructure contraction and expansion due to temperature and shrinkage, assuming th at rotation is possible.

BRIDGE DESIGN MEMORANDUM

The closed cell expansion joint has been used for a few projects with sleeper slabs in New Hampshire The oldest bridge with a closed cell expansion joint with a sleeper slab was built in 2002 On a cold day in February 2017 we inspected a closed cell expansion joint on a bridge in Enfield, NH (Main Street over Mascoma Lake).

Bridge Design- Bridge Deck Joints

Choice of Deck Joint Current practice is to make decks integral with the abutments The objective is to avoid the use of joints over abutments and piers Expansion joints are prone to leak and allow the ingress of de-icing salts into the bridge deck and substructure.

LINK SLAB DESIGN

than one joint to accommodate thermal movement, link slabs at the interior supports and joints at both abutments is preferred Joints at intermediate supports are unavoidable for long bridges with a large number of spans where thermal movements are too large to be accommodated by expansion joints at the abutments alone Bearing Type & Arrangement.

Goodco Z-Tech expansion joints prevent structural damage

Goodco Z-Tech expansion joints are custom-designed and fabricated to accommodate the structural movements of highway bridges, multi-level parking garages as well as various civil engineering works such as dams, airports and others Expansion joints ensure the continuity of bridge traffic while ensuring a watertight seal on the deck.

New Construction Expansion Joint Systems Bridges

expansion joint systems must remain watertight to protect the bridge superstructure and substructure from corrosion To satisfy the demanding needs of bridge expansion joint systems, DS Brown is committed to product research and development, supported by world-renowned, independent testing laboratori For example, DS Brown pioneered.

Integral bridges

At the transition between the surfacing on the bridge deck and the pavement beyond the bridge, expansion/contraction is usually accommodated by an asphaltic plug joint The maximum total movement range for such joints is stated in CD 357 [4] as 40mm, which effectively limits the length of an integral bridge to around 80m.
