    Sammanfattning : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. LÄS MER

  3. 2. Analysis of Response and Development of Permanent Deformation of Unbound Granular Materials Using a Testing Box Technique

    Författare :Ebrahim Parhamifar; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unbound granular materials; testing box; response; permanent deformation;

    Sammanfattning : The main objective of this thesis is to study the response and development of permanent deformation in unbound granular materials, theoretically and experimentally. A testing box technique is used here to more closely simulate the behaviour of unbound aggregates subjected to external vertical loading. LÄS MER
