2021: Materials for Transportation Infrastructure
KTH Materials Dialogue Day is a digital event (Zoom) for materials related research at KTH Royal Institute of Technology, including scientific presentations and policy information and is intended for a general audience. The topic of the 2021 September 23rd event will be on Materials for Transportation Infrastructure focusing primarily on roads and railways. The workshop will highlight the eminent importance of materials research for development of a sustainable, efficient, adaptive, and safe transport infrastructure.
There is an urgent need to find new close-loop solutions for a sustainable development and maintenance of transportation infrastructure at increasing transportation and mobility demands, constrained public sector budgets and climate challenges. Addressing these issues requires new and heavily improved infrastructure materials, optimized from functional, reliability and life cycle perspectives.
Development of innovative infrastructure materials with focus on improved durability, low energy, all-weather workability, as well as materials recycling and reuse is thus already an active area of research with high future potential. Material technology developments are also important enablers for expanding infrastructure functionality beyond transportation to areas such as energy-harvesting, urban climate regulation, water retention, transport and cleaning.
Understanding the link between material design, production, application, and its long-term performance in the field is crucial for both development of infrastructure materials and their implementation in practice as well as their societal acceptance. In this context, new experimental and modelling tools dealing with material mechanics, chemistry and physics are of particular importance.
