The author uses two case studies to describe approaches used for collecting and analyzing asset management data. The first case looks at rural roads condition assessment and prioritization in several districts of Rwanda. While the second case is not in roads, it is so relevant and the methodologies so comparable that it is used to provide a more complete picture of the asset management’s data [...]

Concrete pavements can provide near maintenance-free service for years. However, as their lives come to an end their behaviours become unstable, and their deterioration is difficult to predict. In UK, majority of concrete pavements was built in between 1950 and 1985. These assets represent what National Highways call ‘legacy concrete pavements’ (LCP). The LCP assets are nearing the end of their [...]
