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. Towards frost damage prediction in asphaltic pavements

   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
