  2. 1. Influence of aggregates on permanent deformation of asphalt

    Author : Bernardita Francisca Lira Miranda; Robert Lundström; Stefan Larsson; Alan Carter; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt; deformation; rutting; gradation; flakiness index; Asfalt; kornstorleksfördelning; flisighetsindex; permanent deformation; spårbildning.; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : One of the most common failure modes for asphalt pavements is the occurrence of permanent deformation on the wheel path. This leads to not only other distresses, such as potholes and stripping, but also decreases substantially road safety and increases maintenance costs. READ MORE

  4. 2. DISCO - Drivers and Impacts of Coastal Ocean Acidification

    Author : Laurie Charrieau; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coastal ocean acidification; Foraminifera; Environmental changes; pH; Salinity;

    Abstract : Ocean acidification, mainly attributed to the increasing anthropogenic CO2 in the atmosphere, is characterised by a lowering pH together with a shift in the sea water carbonate chemistry toward lower concentration of carbonate ions. On the coasts, where the environmental variability is high due to natural and human impacts, ocean acidification mainly affects the frequency, magnitude, and duration of lower pH and lower calcium carbonate saturation events.

  5. 3. Modelling effects of climate change and forestry on weathering rates and base cation cycling in forest soils

    Author : Veronika Kronnäs; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; weathering; forest; biogeochemistry; Dynamic Modelling; ForSAFE;

    Abstract : Base cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. READ MORE
