  1. 6. 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. 7. On a finite element method for estimating the penetration of frost in ground : discussion and numerical experiences

    Författare :Harry Hanse; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : .... LÄS MER

  4. 8. Modeling of frost heave and surface temperatures in roads

    Författare :Åke Hermansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Temperature and moisture are very essential parameters when describing the condition of a pavement. In most cases, a high moisture content involves a decreased bearing capacity and, consequently, a shorter durability of the pavement. A frozen pavement has a greater bearing capacity than the corresponding construction in spring or late autumn. LÄS MER

  5. 9. Environmental Actions and Response - Reinforced Concrete Structures exposed in Road and Marine Environments

    Författare :Anders Lindvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement corrosion; marine environment; frost action; bridges; concrete; chloride; de-icing salt; environmental actions; road environment; moisture conditions;

    Sammanfattning : The expenses for repair, maintenance and remediation of existing concrete structures have significantly increased. A large proportion of these expenses are due to problems related to a lacking durability of the structure. LÄS MER

  7. 10. Building Physics Tools: Needs, Use and the Lack of Use in the Building Process. Modelling Non-Isothermal Moisture Flow and Frost Penetration

    Författare :Stephen Burke; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal; costs; building physics tools; moisture damages; learning loop; experience; causal loop diagrams; non-isothermal; moisture transport;

    Sammanfattning : Despite advances in material science, computers and building technology, building failures related to building physics continue to occur. These failures range from a building not meeting its energy use target to a building causing people to become ill from exposure to various chemicals or biological organisms. LÄS MER
