  2. 16. Soil Modification by adding small amounts of binders : A laboratory study

    Author : Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.

  4. 17. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests

    Author : Richard Nilsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; viscoelastic; Fatigue; deterioration models; Continuum Damage Mechanics; laboratory test; uniaxial; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

  5. 18. Laboratory Investigations of Frost Action Mechanisms in Soils

    Author : Deniz Dagli; Jan Laue; Tommy Edeskär; Lukas Arenson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold Regions Soil Mechanics; Frost Action; Frost Depth; Frost Heave; Heat Flow in Soils; Ice Lens Formation; Image Analysis; Laboratory Freezing Test; Soil Mechanics; Geoteknik;

    Abstract : Phase change of the water in the soil skeleton under cold climate conditions (also known as frost action in soils) affects soil properties and can be responsible for serious alterations in a soil body; causing damages (due to the volumetric expansion known as frost heave) to structures on or below the ground surface such as foundations, roads, railways, retaining walls and pipelines, etc. In order to improve the current design methods for roads against frost action, the Swedish Transport Administration (Trafikverket) has initiated a research program.

  6. 19. On a mathematical basis for constitutive drivers in soil plasticity

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

    Abstract : Huvudsyftet med denna avhandling har varit att vidareutveckla en matematisk grund för konstitutiva drivenheter inom området plasticitetsteori för jord. Med en konstitutiv drivenhet avses här en datorrutin som innehåller ett antal utvalda konstitutiva modeller jämte integrationsmetoder och med vilken olika laboratorieförsök och fältförsök kan simuleras numeriskt och modellparametrar bestämmas genom optimering.

  7. 20. Identification of soil parameters in an embankment dam by mathematical optimization

    Author : Pooya Vahdati; Hans-Åke Häggblad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The finite element method (FEM) has been widely used to analyse earth and rockfill dams. In a finite element analysis a proper constitutive model has to be chosen for each part of the dam in order to simulate the relation between stresses and strains. The zones of an earth and rockfill dam have different functions. READ MORE
