References
Bearing in mind that the amount
of money spent on expansion
joints in bridges comes up to
approximately 1.5% of the total
structural costs only, it is certainly
short-sighted to evaluate solely the
purchase price of these important
bridge members. The initial
savings can gener-ate tremendous
costs later on, if the joint system
chosen fails.
