The deterioration of road bridges and culverts that mainly called road structure is a common incident worldwide due to various phenomena that significantly affect Asset management. There is a significant backlog in Asset maintenance, rehabilitation, or upgrade worldwide from literature, and asset Owners are fumbling for funding to line up these backlogs and ensure safety and mitigate risks with a systematic process; operation and maintenance, developing, upgrading or disposing of. An efficient structure inventory is a pivotal part of Asset management that could help rich data establish the governance approach. Besides, an adequate inventory assists asset owner (the government agency) in identifying the Life Cycle Cost (LCCA), prioritisation, optimisation costs (Benefit-Cost ratio), and performance to achieve a sustainable approach. The study object is to bring a perfect case example from Uiar – Yevlakh Road Rehabilitation Project, Azerbaijan for academic and practitioner how to assess and find the Structural adequacy, design standard, appropriateness, hydrological condition, protection designs, aesthetics, and many more. Besides, it could assist in design economical, functional, durable structures for the project. The study found that adopting this methodology could suit other similar road development projects, where the author used and successfully completed inventory for small scale to large scale projects. The study concludes that due to the lack of timely inventory measures, deterioration often causes severe structural damage, a little opportunity for a structural engineer to revitalise, and warrant untimely expensive repair or replacement of the whole structures. The findings will help comprehend quality decision-making in cost for asset owners to collecting enrich data for assets in the selection, optimisation and ranking the following examples, and adopting the case and samples (detailed in this study). The closing discussion will also offer some potential tonics for the data collection shortcomings or literature gaps.
