spans of a bridge deck or between a bridge deck and an abutment. Due to the exposure of expansion joints to traffic loads, heat and cold, and atmospheric corrosion they tend to deteriorate faster than other bridge components and require several replacements during the
Use of Longitudinal Expansion Joints in Wide-Bridge Applications to Reduce Deck Cracking. It is a very common practice to use longitudinal expansion joints to create dual-direction bridges in applications that would have otherwise resulted in bridges that are very wide.
Design parameters occasionally require a longitudinal joint in the bridge deck to accommodate extreme bridge width, jumps in elevation across the width of the deck…

Abstract. The primary objective of this project was to determine the effect of bridge width on deck cracking in bridges. Other parameters, such as bridge skew, girder spacing and type, abutment type, pier type, and number of bridge spans, were also studied.
Joints in bridges can be compared to a cut in the skin, with the expansion joint as a bandage. Over time, the bandage can become damaged, allowing foreign materials (salt and water) to enter the underlying tissue (beams and bearings), allowing infection (corrosion) to cause damage to the body (bridge).
Many bridge deck expansion joints on the TLRN are coming to the end of their design life. During winter 2009 and throughout 2010, several expansion joints failed …
Unfortunately, the introduced longitudinal expansion joint can result in deterioration similar to that resulting from using transverse joints at bridge abutments and piers. The reason that longitudinal expansion joints are used in wide bridges is related to concerns about deck cracking resulting from constrained expansion and contraction.
Function Bridge expansion joints have to function as "riding plates" to carry the imposed traffic loads and also accommodate the thermal movement, shrinkage, pre-stress creep and rotation of the deck.

The bridge designer should specify the expansion joints in a similar manner to bearings, giving details of characteristic and design values of displacements to the joint designer. Annex B of BS EN 1993-2  contains guidance for the preparation of a technical specification for expansion joints.

Approval of the supervising Section Leader is required for strip seals designed for longitudinal bridge deck movements greater than those given in Table 188.8.131.52.1-2.
Expansion joints are used in bridges to allow movements like expansion and contraction between the bridge deck spans and abutments. These movements are caused due to temperature, soil settlements, vehicle acceleration and other reasons (Klaiber, et al., 1987 and Dagher, et al., 1993 as cited in Thippeswamy, 2002).
