  1. 11. Adaptation of road drainage structures to climate change

    Författare :Zahra Kalantari; Lennart Folkeson; Steve W. Lyon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Climate change is expected to lead to more frequent extreme precipitation events, floods and changes in frost/thawing cycles. The frequency of road closures and other incidents such as flooding, landslides and roads being washed away will probably increase. Stronger demands will be placed on the function of road drainage systems. LÄS MER

  3. 12. Seasonal variation of road runoff in cold climate

    Författare :Camilla Westerlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of this thesis was to characterize and study the behaviour and transport of pollutants, i.e., suspended solids, particles and heavy metals, in road runoff from a small urban catchment during snowmelt and rainfall. LÄS MER

  4. 13. Sustainable Personal Road Transport : The Role of Electric Vehicles

    Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

    Sammanfattning : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. LÄS MER

  5. 14. Urban Climate and Air Pollution in Ouagadougou, Burkina Faso

    Författare :Jenny Lindén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sub-Saharan Africa; Sahel; semi arid; nocturnal cooling; urban vegetation; evening evaporative cooling; cooling rate; atmospheric stability; thermal wind; carbon monoxide; particulate matter; road dust; exposure differences;

    Sammanfattning : ABSTRACT Africa has recently been singled out by UN Habitat as the fastest urbanizing continent in the world. The most extreme case was found in the Sahelian city of Ouagadougou, Burkina Faso, where the population is expected to almost double over the next ten years. LÄS MER

  7. 15. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations

    Författare :Raheb Mirzanamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal properties; slippery condition; hydronic heating pavement; energy harvesting; asphalt concrete; road; anti-icing; finite element method;

    Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER
