Case study report: Deliverable D4.1

The work in this report has been carried out under WP4. It has focussed on selecting emerging technologies from the work carried out in WP1-3, to identify case studies that have demonstrated success in the use of these technologies to bridge the gaps between current practice and future needs identified in WP1. The work has developed a semi-formalised approach to undertake assessment of the technologies at the level of “case study” - which can provide further detail on the technologies, including information on the costs associated with their implementation. The report presents specific case studies applying new technologies to assess pavement and bridge condition including: mobile imaging; aerial satellite spectroscopy; a virtual bridge inspection platform; a wireless acoustic emission measurement system; and bridge weigh-In-motion technology. Each study is summarised in the report, but a separate INFRACOMS Case study catalogue has been provided that presents the studies in full detail. The report presents the approach taken to undertake the case study, with the expectation that NRAs could apply this approach in the future. The approach/outcomes will be taken forward for integration into WP2's Tier 3 Technology Appraisal, which will be included in the INFRACOMS database.
