19-01 — Leading Practices for Detailing Bridge Ends and Approach Pavements to Limit Distress and Deterioration

Bridge owners seek to design and construct structures with details and materials that will minimize maintenance and repair costs. One strategy for doing so in design is to minimize the number of joints in the structure. While this approach has proven to improve durability of the structure itself, thermal expansion and contraction of the structure must still be accommodated and loads must be transferred between structural segments when joints are required. Detailing and maintaining joints at bridge ends are notoriously challenging not only because the transition from one structure to another often becomes noticeable to road users as “bump at the end of the bridge,” but also because the displacements and forces at these locations are particularly prone to cause damage to riding surfaces and structural elements. Bridge owners have adopted a wide variety of design details to avoid this damage and have sought to understand the causes of observed distress. This scan will seek out leading design and management practices for minimizing structural distress and surface discontinuity on approaches to jointless bridges.

This scan will meet with agencies having experience in dealing with distresses observed on approaches to jointless bridges. The team will seek to identify tools that can assist in the selection of the appropriate details for use at the ends of bridges. Sharing of these tools nationwide will improve the performance and durability of jointless bridges.
