Climate change has undoubtedly arrived, regardless of the debate over the causes of it. Such change is having a considerable impact on the highways and pavements in the UK. Extreme weather, whether it be drier summers or wetter winters, can lead to pavement and highway deterioration, all of which must be repaired. In order to avoid increased disruption of services and highway maintenance costs, it is vital to plan for and adapt to the climate change predicted for the future, rather than basing decisions on historic climate. The implications of this different climate for highway maintenance on the different pavement types are described in this report. Also contained within the report is advice for highway engineers on assessing the risk of different climate hazards for their network. Recommendations are given on how to reduce the risks associated with climate change by ensuring good construction and maintenance practice, and using adaptive maintenance techniques. Also included are case studies on the impacts weather can have on highways. Adaptive techniques already trialled, both in the UK and abroad, are used to illustrate the guidance.This publication is essential for local authorities and construction firms wishing to plan for the future and wanting improve their understanding of the effects and implications of climate change.
