  1. 21. Morphology Characterization of Foam Bitumen and Modeling for Low Temperature Asphalt Concrete

    Författare :Biruk Hailesilassie; Manfred Partl; Kim Jenkins; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; foam characteristics; evolution of foam bitumen bubbles; image analysis; modeling rising of bubble; foam asphalt mixture; Transportvetenskap; Transport Science;

    Sammanfattning : Development of new asphalt technologies to reduce both energy consumption and CO2 production has attracted great interest in recent years. The use of foam bitumen, as one of them, is attractive due to the low investment and production cost. LÄS MER

  3. 22. Characterisation of thermally modified wood for use as component in biobased building materials

    Författare :Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.

  4. 23. Surface characterisation of thermally modified spruce wood and influence of water vapour sorption

    Författare :Susanna Källbom; Magnus Wålinder; Kristoffer Segerholm; Dennis Jones; Marko Petrič; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermally modified wood; Norway spruce; inverse gas chromatography IGC ; dynamic vapour sorption DVS ; X-ray photoelectron spectroscopy XPS ; surface energy; Värmebehandlat trä; gran; omvänd gaskromatografi IGC ; dynamic vapour sorption DVS ; röntgenelektronspektroskopi XPS ; ytegenskaper; ytenergi;

    Sammanfattning : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. LÄS MER

  5. 24. Non-Exhaust PM10 and Road Dust

    Författare :Joacim Lundberg; Sigurdur Erlingsson; Mats Gustafsson; Sara Janhäll; Göran Blomqvist; Brynhild Snilsberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road Dust; Abrasion Wear; Road Surface Macro Texture; Mean Profile Depth; Mean Texture Depth; Emissions; Abrasion Wear Model; NORTRIP; PM10; Air Quality; Particles; Vägdamm; Vägslitage; Dubbslitage; Textur; Emissioner; Slitagemodell; NORTRIP; PM10; Partiklar; Luftkvalitet; Byggvetenskap; Civil and Architectural Engineering; 15 Road: Environment;

    Sammanfattning : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. LÄS MER

  7. 25. Development of a Morphology-based Analysis Framework for Asphalt Pavements

    Författare :Ibrahim Onifade; Björn Birgisson; Nicole Kringos; Denis Jelagin; William G. Buttlar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; damage; X-ray computed tomography; top-down cracking; fracture; Morfologi; skador; röntgendatortomografi; ’top-down’sprickbildning; fraktur; Byggvetenskap; Civil and Architectural Engineering; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The morphology of asphalt mixtures plays a vital role in their properties and behaviour. The work in this thesis is aimed at developing a fundamental understanding of the effect of the asphalt morphology on the strength properties and deformation mechanisms for development of morphology-based analysis framework for long-term response prediction.
