Numerical modelling and experimental verification of GPR to investigate ring separation in brick masonry arch bridges
For the first time it was shown that GPR can penetrate brick masonry rings and identify the presence of and thickness of a clay waterproofing saddle above the rings. This work, funded by NetworkRail, is expected to save up to £2M per bridge in unnecessary maintenance (Brian Bell, ex-NetworkRail, email available), with ownership of 40,000 bridges. When applied to European rail bridges the savings could extend to €10M per annum. The work has inspired international researchers to develop novel hybrid NDT procedures: Spain, DoI:10.1016/j.engstruct.2011.11.004; France, DoI:10.1080/15583058.2011.597484; Italy, DoI:10.3997/1873-0604.2012047; and Poland, DoI:10.1016/j.ndteint.2012.03.001.
