This assignment was NCHRP Project 10-52, Performance Testing of Modular Bridge Joint Systems. The purpose of this project was to develop performance requirements for modular bridge joint systems (MBJS), which permit large movements and prevent corrosive roadway runoff from leaking onto the bridge beams and substructure. The report includes recommended testing specifications; material, fabrication, and construction guidelines; and a joint anchorage design example.

Modjeski and Masters, Inc. participated in this project as a subconsultant to the University of Minnesota, providing expertise in the design and rehabilitation of MBJS.

Modjeski and Masters provided the following services for this project:

• Literary review of current practices and performance test data associated with MBJS.

• Attend site visits of MBJS installations.

• Participate in the identification and prioritization of important fabrication, installation, inspection and other performance factors applicable to MBJS.

• Participation in the identification of performance requirements and development of test procedures.

• Participation in the development of specifications and guidelines for the installation and construction inspection of MBJS.
