ABSTRACT
In this chapter the term ‘repair’ is taken to mean an activity which involves
the removing or cleaning of defective building materials which are then
replaced and protected in a suitable way. It may also include some decorative
enhancement to restore the appearance of the bridge. Repair works generally
add no extra strength to the bridge structure, but are merely curative
measures taken to restore the serviceability of the bridge – rather like taking
out decayed matter in a tooth and replacing it with an amalgam filling
followed by a ‘brush and clean’.
