Abstract
Findings of this report indicate that most joint failures are caused by traffic loading, faulty installation, poor detailing, or movements much less than the maximum expected, and that there are wide variations in the performance of joints, particularly with regard to durability. There is general agreement that the number of joints on a bridge should be kept to a minimum, and where they have to be used sub surface joints are preferred. On busy roads, traffic management and delay costs for major repair or replacement are such that the cost of the joint is almost irrelevant - it is always worth paying extra for increased service life.
