  4. 3. Smart pavement maintenance and infrastructure operation through digital twins : Case study for Norvik Port, Sweden

    Författare :Julian Dario Rodriguez; Nicole Kringos; Romain Balieu; Plati Christina; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement management; digital twins; finite element model pavement; infrastructure maintenance.; Vägunderhåll; Digitala tvillingar; Ändliga elementmodeller för vägar; Infrastrukturförvaltning; Civil and Architectural Engineering; Byggvetenskap; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. LÄS MER

  5. 4. Vehicle-Pavement Interaction

    Författare :Parisa Khavassefat; Björn Birgisson; Denis Jelagin; David Cebon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element; Viscoelasticity; Moving load; Dynamic axle loads; Road roughness; Flexible pavement; Stochastic;

    Sammanfattning : Several aspects of vehicle-pavement interaction have been studied and discussed in this thesis. Initially the pavement response is studied through a quasi-static and a dynamic computationally efficient framework under moving traffic loads. LÄS MER

  7. 5. Deterioration Models and Road Capital as Tools in Performance Contracts for Pavement Maintenance

    Författare :Peter Ekdahl; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; pavement management system; performance contract; pavement maintenance; deterioration model; Technological sciences; road capital; Social sciences; Samhällsvetenskaper;

    Sammanfattning : A reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. LÄS MER
