Abstract:
Addresses the need for a consolidated effort when dealing with expansion joints at bridge rehabilitation projects. It stresses the importance of careful planning, especially in respect to handling traffic at major highways. It also stresses that economics could play secondary roles when the safety and convenience of the general public is the main concern. The paper underlines the consequence of the interplay between the design and construction of expansion joints, considering that very often insufficient existing data is all that is available to the designer. Proper quality control, such as material tests and water tests, are highlighted. Also, yearly reviews of inspections and maintenance requirements are outlined. The significance of user and supplier committees is discussed together with the required cooperation between parties. The paper emphasizes the need for each road authority to develop its own guidelines without blindly adopting the recommendations of the authors.
