  1. 1. Modeling frost heave damages throughout the asphalt layer

    Författare :Saeed Vosoughian; Romain Balieu; Inge Hoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt pavement; Frost heave; Viscoelastic damage model; Thermomechanical approach.; Asfaltbeläggning; tjällyft; viskoelastisk skademodell; termomekanisk ansats.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : There are various distresses arising from traffic loads and the surrounding environment to whichan asphalt pavement is subjected during its life span. The environment-associated damages aremore severe during winter when abundant moisture and freezing temperature are presentsimultaneously. LÄS MER

  3. 2. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures

    Författare :Ibrahim Onifade; Björn Birgisson; Linbing Wang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-based models; damage; X-ray computed tomography; continuum plasticity mechanics CPM; effective micro-crack stress; Transportvetenskap; Transport Science;

    Sammanfattning : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this  is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.
