Strategic Theme 4 - Resilient Infrastructure

Resilient road infrastructure is essential for ensuring the safety and reliability of our transportation systems. Building and maintaining roads that are able to withstand natural hazards and other challenges, we can help ensure that people are able to travel safely and efficiently.

Strategic Theme 4 "Resilient Infrastructure" responds to the key infrastructure issues aims to provide information on how to address them.

Technical Committees


Technical Committee 4.1 "Pavements" addresses issues related to mitigating and managing the resilience of pavements due to climatic events, use as well as natural deterioration.

Technical Committee 4.2 "Bridges" considers issues related to ensuring safe and reliable bridges to maintain the connectivity of transportation systems and ensuring the safety of road users. This will include innovative approaches to withstanding natural hazards as well as improved inspection and maintenance approaches.

Technical Committee 4.3 "Earthworks" addresses issues related to embankments, cuttings and retaining walls that provide support and stability to the road system.

Technical Committee 4.4 "Tunnels" addresses issues related to the construction, operation and use of tunnels.

Technical Committee 4.5 "Decarbonisation of Road Construction and Road Maintenance" addresses issues related to the construction and maintenance of roads and other transportation infrastructure in order to reduce greenhouse gas emissions. Decarbonisation efforts, such as the use of low-carbon materials and the adoption of sustainable construction practices, can reduce the carbon footprint of road construction and maintenance, making transportation systems more resilient to the impacts of climate change.

Technical Committee 4.6 "Road Design Standards" addresses issues related to road design standards, for comparisons of applicable standards, and for recommending their use in other countries, mainly Low or Middle Income Country (LMIC).
