Abstract
A large amount of infrastructure in North America is in need of repair or replacement. The cost of these improvements is a huge obstacle for governments and the issue will be exacerbated in the coming years as current infrastructure, including bridges, get closer to the end of their design life (The Age of Public Infrastructure in Canada http://www.statcan.gc.ca/pub/11-621-m/11-621-m2006035-eng.htm, 2009; 2013 Report Card for American Infrastructure http://www.infrastructurereportcard.org/bridges/, 2013). The use of prescribed maintenance is no longer efficient or cost effective enough to continue to be used as a means of upkeep for bridges. Indeed, new methods are being developed in order to gain a deeper understanding of the state of bridges so that more precise maintenance can be carried out.
