Subject(s): Online resources: Abstract: The proposed project will : - study the likely differences in moisture (water) condition in the pavements of roads in Europe, from the Alps and northwards, as a consequence of climate change; - estimate the likely consequences for pavement and subgrade material behaviour and for whole pavement needs in terms of : - reformulation of material composition, - new and modified drainage practice, - modification to maintenance practice and rehabilitation; - perform this study for a range of representative pavement types (asphaltic, unsealed, intercity, county, low-volume) and representative climatic zones (temperate maritime, temperate Mediterranean, continental warm summer, continental sub-arctic); - assess uncertainties to permit risk / vulnerability to be evaluated; - define options for responding to the changes, identifying key selection criteria; - perform exemplar cost-benefit analyses to allow road owners to detrermine best optioons for their own situations; - formulate findings into a wide range of formats (published, brochure, web, educational, email) and disseminate them accordingly. The project will be performed by a combination of literature review, laboratory evaluation of materials, computational studies of pavement structural and hydrological performance and by the development of recommendations suitable for implementation by national road owners into their specifications and design guides. An advisory panel drawn form a selection of national road authorities will be assembled to advise on goals and progress and to critically examine the outputs to permit their improvement.
