This project (2012-2014) developed surfacing materials to mitigate impacts of climate
change in urban environments. The new materials are surfacing layers of
permeable concrete, asphalt and stone together with sub-base structures of
aggregate, pipes, geotextiles and water storage tanks.
The system was optimized during design, construction and maintenance, allowing
high filtration of water to the substrate rather than burdening stormwater
collection systems or transporting run-off pollutants to local water bodies.
Structures were optimized for Nordic environments, while addressing water
chemistry and vegetation interactions. Computer flood simulations were combined
with climate forecasting to evaluate impacts, while structural dimensioning
improves stormwater design tools.
