68 ConClusions Concrete cracking in bridges is complex and unlikely to be caused by a single effect. In some situations, cracking cannot be avoided.

70 connection details for adjacent precast concrete box beam bridges to eliminate cracking and leakage in the longitudinal joints between adjacent boxes. Pretensioned Concrete Beams End zone cracking in prestressed concrete beams is an uncommon occurrence but can be prevented by modifying the detensioning sequence.

From page 71... ...
71 The application of the existing articles to control flexural cracking in structures with these new types of reinforcement may not be appropriate and in some cases can result in unnecessary increased costs or impractical designs. Consequently, a fresh look is needed to ensure that design provisions for flexural crack control are provided that address all types of reinforcement.
