  7. 5. 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
