The International Road Federation (IRF) has concluded a first-of-its-kind training programme on Climate-Resilient Road Design and Maintenance, delivered in partnership with ORIS Materials Intelligence to worldwide road practitioners.

The increasing frequency of climate-related disruptions is forcing road agencies to move beyond reactive maintenance and toward structured, forward-looking decision-making. While climate resilience is now firmly embedded in national strategies and multilateral development frameworks, the road sector has so far lacked structured, operational guidance to implement it at project and network level. This course set out to bridge that gap, moving beyond concepts and into actionable engineering and financial choices that can be applied in real-world decision-making contexts.

A first pillar of the course focused on diagnosis. Participants explored how to assess exposure, sensitivity and risk using available data, combining climate projections with asset condition and network criticality. Importantly, the emphasis was not on complex modelling alone, but on structured, scalable approaches that can be deployed across entire networks, even in data-constrained environments.

From there, attention shifted to intervention planning. The discussion outlined how design adaptations and maintenance strategies can be aligned with identified risks, ensuring that responses are neither over-engineered nor insufficient. The emphasis was place on proportionality, which matches the scale of intervention to the level of risk, while maintaining service continuity and cost efficiency.

Investment decision-making formed the third pillar of the course. Here, the session explored how resilience measures can be evaluated within existing budgeting frameworks. Rather than treating climate adaptation as an external cost, the discussion reframed it as part of lifecycle optimisation. Approaches such as risk-informed prioritisation and cost-benefit analysis were examined, particularly in contexts where funding constraints require clear justification for every expenditure.

What emerge is a structured pathway: diagnose, prioritise, invest. The value lies less in any single tool and more in how these elements are integrated into a coherent decision-making process.

For agencies navigating competing pressures such as network expansion, maintenance backlogs and climate pressures, this integrated approach offers a way to align technical choices with financial realities.

Crucially, the course also emphasised that resilience is no longer a niche or optional consideration. With global adaptation financing needs projected to reach up to $1.3 trillion annually by 2030, and regulatory frameworks increasingly requiring climate-proofing of infrastructure investments, the ability to demonstrate robust, evidence-based decisions is becoming a core competency for road agencies.

“Leading these sessions with the IRF allowed us to share a structured approach that aligns technical engineering considerations with the financial realities of the Paris Agreement,” noted Hugo Pley-Leclercq, Project Director at ORIS Materials Intelligence and one of the course’s lead instructors. “The level of engagement demonstrated that practitioners are actively seeking to translate resilience into actionable, investment-ready decisions.” – Renaud De Montaignac, COO and Managing Director of ORIS Materials Intelligence

In a context where climate risks are accelerating but resources remain finite, the ability to make defensible, data-informed decisions is becoming a defining capability. This course thus provided a key learning opportunity at the intersection where engineering judgment, data and investment strategy converge.
