ADB Case Study

A Multi-Criteria Impact Assessment for the A380 Road Upgrade in Uzbekistan

 

Project Overview

As part of the ADB Digital Sandbox Program (Digital Services & Innovation), ADB CWTC (Transport & Communication Division) partnered with ORIS to pilot a multi-scenario digital analysis for the upgrade of the A380 road section (673 - 698 km) in Uzbekistan.

The goal was to evaluate pavement design alternatives using a data-driven approach, ensuring:

  • Enhanced mechanical performance over the lifecycle
  • Sustainability & circular economy integration
  • Improved road safety aligned with UN targets
  • Climate resilience assessment over 40 years

Approach & key solutions

________________

 

  • Data-Driven Comparative Analysis

    After compiling and processing local construction materials into the ORIS platform, the project team conducted a multi-criteria assessment across:
    - Pavement performance & lifecycle durability
    - Circular economy & resource efficiency
    - Carbon emissions & environmental impact
    - Water consumption & sustainability

  • Road Safety Optimization


    Leveraging iRAP’s international assessment methods, the project evaluated potential safety improvements to meet and exceed the UN’s 3-star safety target.

  • Climate Resilience Evaluation (40-Year Model)

    A thorough climate change risk analysis was conducted, identifying key risks such as:
    - Extreme heat
    - Frost/thaw cycles
    - Flooding & water runoff
    - Silting & landslides

    This enabled the identification of effective countermeasures to future-proof the infrastructure.

Impact & key results

________________

 

The integration of ORIS and multi-scenario analysis led to significant improvements:

 

  • -10% in costs through optimized design choices

  • 17% in carbon emissions, supporting sustainability goals

  • -30% reduction in natural resource usage for road materials

  •  

    5M liters of water saved by selecting more sustainable construction methods
  • Road safety enhancements aligned with UN targets, preventing 1,800+ serious injuries & fatalities
  • Comprehensive climate risk analysis (40 years) to identify & mitigate potential threats
