A Sustainable Asset Valuation (SAVi) of the Uchkuduk-Kazakhstan Border Highway in Uzbekistan

This methodological note describes the application of the Sustainable Asset Valuation (SAVi) methodology to the construction of the 4R60 "Uchkuduk – border of the Republic of Kazakhstan" highway in Uzbekistan. The project aims to improve regional connectivity, increase freight capacity, and enhance road safety through the construction of 166.577 km of road infrastructure between 2021 and 2025.

• The project involves the construction of 166.577 km of the two-lane road 4R60 "Uchkuduk – border of the Republic of Kazakhstan" (section 0-198 km) to improve throughput capacity and reduce travel time. The implementation period is scheduled from 2021 to 2025.
• The total projected investment cost for the highway is USD 549,931.484. Funding is split between Eximbank, providing USD 463,081.991, and the government of Uzbekistan, providing USD 86,849.493.
• The project's objectives include reducing the accident rate by 10%–30%, increasing the proportion of category II public roads with a 13-tonne axle load, and improving access to border crossing points and transport hubs.
• The SAVi analysis utilizes three scenarios: a "No action" scenario where no infrastructure is built; a "Low cost of accidents" scenario considering only direct costs (e.g., medical costs and vehicle repair); and a "High cost of accidents" scenario that includes indirect costs such as the loss of national income due to death or permanent disability.
• The highway design specifies a rigid pavement with a total thickness of 97 cm and an average service life of 25 years before overhaul. This includes a 27 cm monolithic cement–concrete coating and various base layers of crushed stone, gravel, and sand.
• For access roads and the overhaul of the existing 4P60 road, a non-rigid pavement design is used with a total thickness of 61 cm and an average service life of 16 years, featuring asphalt concrete coatings.
• The environmental impact assessment identifies several added benefits and avoided costs, including a cumulative value of time saved estimated at USD 16,889,500 and estimated cumulative road maintenance cost savings of USD 136,278,74.
