  4. 2. Thaw Mechanism in Subgrades

    Author : Amin Zeinali; Jan Laue; Tommy Edeskär; Sven Knutsson; Guy Dore; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Freezing-thawing, changes the properties of soil due to the phase change of the water in the soil body. Freezing-thawing cycles in the soil have been studied for several decades including extensive laboratory research. In this study, the main focus is thawing based on laboratory investigation.

  5. 3. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

    Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

  6. 4. The behaviour of mica-rich aggregates under the temperate climate conditions

    Author : Evgeny Novikov; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : In regions of temperate climate the destructive influence of frost action such as frost heave in winter and thaw weakening in spring are the main contributors to severe deterioration of the pavement structure. A number of studies on construction aggregates and field observations of road failures, especially caused by seasonal fluctuations of temperature, have revealed a negative influence of unbound mica-rich rock aggregates on the service life of road construction.
