  4. 3. Towards frost damage prediction in asphaltic pavements

    Författare :Lisa Lövqvist; Nicole Kringos; Romain Balieu; Robert Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frost damage; winter damage; asphalt; pavements; micromechanical model; microstructure; freeze-thaw cycles; finite element model; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Roads are subjected to mechanical loads from the traffic as well as deteriorating mechanisms originating from the surrounding environment and climate. The damage arising is particularly severe during the winter season, when for example raveling, pot holes and cracks can emerge on the surfaces of asphaltic roads. LÄS MER

  5. 4. Spherical Indentation Technique for Multiscale Characterisation of Asphalt Mixtures

    Författare :Hassan Fadil; Denis Jelagin; Manfred Partl; Per-Lennart Larsson; Said Safwat; Eshan Dave; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building Materials; Byggnadsmaterial;

    Sammanfattning : The viscoelastic properties of asphalt  mixtures  strongly  influence the  performance of flexible pavements  with respect to  their resistance to several common distress modes. Therefore, accurate measurement of these properties and their change during the service life is an important area of ongoing research. LÄS MER

  7. 5. New Experimental and Modelling Tools for Multiscale Characterization of Asphalt Mastic

    Författare :Hassan Fadil; Denis Jelagin; Robert Ingemar Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building Materials; Byggnadsmaterial;

    Sammanfattning : Asphalt mastics act as a binding phase in asphalt mixtures and their rheological properties strongly affect the performance of asphalt mixtures with respect to virtually all damage modes. In order to measure mastics properties, relevant for field performance, testing should be performed at size-scales representative for the morphology and material inhomogeneity of asphalt mixtures.
