  1. 1. 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

  3. 2. Biomechanical Analysis of Fall Injuries using Finite Element Modeling

    Författare :Pooya Sahandifar; Svein Kleiven; Viveca Wallqvist; Yunhua Luo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fall induced injury; finite element analysis; rubberized asphalt mixture; shock-absorbing pavement; hip fracture; elderly; sideways fall; whole-body model;

    Sammanfattning : A fall is a serious health issue for the elderly. Among different fall types, the sideways fall is considered to be more severe concerning the injury outcome. LÄS MER

  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. 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

  7. 5. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations

    Författare :Raheb Mirzanamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal properties; slippery condition; hydronic heating pavement; energy harvesting; asphalt concrete; road; anti-icing; finite element method;

    Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER
