As climate change continues to wreak havoc on infrastructure worldwide, a recent study conducted by Mehvesh Mushtaq from the Department of Engineering and Technology at the University of Huddersfield sheds light on the urgent need for the construction industry to adapt its roadways to withstand the increasing threat of flooding. Published in the journal ‘Construction Materials’, this comprehensive review highlights various structural mitigation and adaptation strategies that can significantly enhance the resilience of roads against flooding damage.
Flooding has emerged as a critical challenge, particularly in urban environments where dense populations and extreme weather events collide. The economic implications are staggering; in the UK alone, the cost of traffic disruption on major roads can reach £100,000 per hour during peak times. With projections indicating a 130-140% increase in annual damage from surface water flooding by 2080, the stakes have never been higher. Mushtaq emphasizes, “The construction sector must prioritize innovative strategies that not only address current vulnerabilities but also anticipate future challenges posed by climate change.”
The study categorizes adaptation strategies based on the timing of intervention, distinguishing between pre-construction design changes and post-construction mitigation options, such as Sustainable Urban Drainage Systems (SuDS). These methods, including swales and bioretention systems, aim to enhance the capacity of urban areas to handle stormwater effectively. Mushtaq notes, “Implementing these strategies during the design phase can drastically reduce the need for costly rehabilitation after flooding occurs.”
One of the key findings of the research is the potential for altering the specifications of commonly used materials to improve flood resilience. For instance, using higher softening point binders and polymer-modified bitumen can mitigate the impacts of extreme temperatures and flooding. The study serves as a guide for engineers and designers, offering a roadmap for integrating these innovative materials and techniques into road construction and rehabilitation.
The implications of this research extend beyond just infrastructure resilience; they signal a shift in how the construction industry approaches design and material selection in the face of climate challenges. The anticipated £4.5 trillion global investment in infrastructure by 2030 underscores the urgency for the sector to adapt and innovate. By prioritizing flood resilience, construction firms can not only safeguard their projects but also contribute to a more sustainable and economically viable future.
Mushtaq’s work not only addresses the immediate concerns of flooding but also sets the stage for future developments in road infrastructure. As the industry grapples with the realities of climate change, the insights from this study will be invaluable for shaping policies and practices that prioritize resilience.

With the construction sector at a crossroads, the strategies outlined in this review could very well define the future of road infrastructure, ensuring that it remains robust in the face of increasingly frequent flooding events.
