Description

This strategic technical report presents a modernized framework for lifecycle infrastructure planning and asset management for the national highway network of Georgia (the country in the Caucasus). Facing increased transit freight traffic along the East-West Highway corridor and complex mountainous terrain, the Georgian Roads Department required an upgraded decision-support system to optimize long-term capital investments and maintenance allocations. The document details the implementation of lifecycle cost analysis (LCCA) methodologies integrated with HDM-4 economic evaluation software and GIS-based asset management tools. It addresses key local challenges, including severe winter weathering, seismic hazards, landsliding risk, and heavy international truck traffic. The report establishes multi-year deterioration modeling strategies for both flexible asphalt and rigid concrete pavements, defining optimal intervention thresholds for preventive maintenance, rehabilitation, and full reconstruction. Furthermore, it incorporates climate resilience criteria into lifecycle decision frameworks, evaluating the cost-effectiveness of enhanced drainage structures and slope stabilization measures. The document serves as an operational blueprint for institutionalizing lifecycle management principles within the Georgian transport sector, ensuring sustainable asset performance and maximizing the return on public infrastructure investments.
