  2. 1. Effect of Compactive Effort on the Behaviour of a Gypsiferous Subgrade Soil

    Author : Dina K Kuttah; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gypsum; Soil; Clay; Compaction; California bearing ratio; Triaxial; Moisture content; Pore water pressure; 62 Road: Soil mechanics; 62 Road: Soil mechanics;

    Abstract : Presented in this thesis is a study of the effect of compactive effort and long-term soaking on strength, stiffness and deformation characteristics of a gypsiferous subgrade soil from Kirkuk city.The tested soil is sandy lean clay (CL) according to the Unified Soil Classification System and A-6 (6) soil according to AASHTO soil classification system.

  4. 2. Soil compaction: effects on soil hydraulic properties and preferential water flow

    Author : Mona Mossadeghi Björklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. READ MORE

  5. 3. Frequency Optimization of Vibratory Rollers and Plates for Compaction of Granular Soil

    Author : Carl Wersäll; Stefan Larsson; Michael Mooney; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compaction; vibratory roller; frequency; resonance; vibration; sand; gravel; soil dynamics; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Vibratory rollers are commonly used for compaction of embankments and landfills. This task is time consuming and constitutes a significant part of most large construction and infrastructure projects. By improving the compaction efficiency, the construction industry would reduce costs and environmental impact. READ MORE

  6. 4. Compaction- and strength properties of stabilised and unstabilised fine-grained tills

    Author : Per Lindh; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Väg- och vattenbyggnadsteknik; Compaction; Fine-grained tills; Strength; Civil engineering; Soil stabilisation modification; hydraulic engineering; soil mechanics; offshore technology; Material technology; Materiallära; materialteknik;

    Abstract : Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. READ MORE

  7. 5. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

    Author : Yevheniya Volchko; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soil ecosystem services; Contaminated sites soil; minimum data set; remediation; sustainability assessment; soil quality indicators; soil functions;

    Abstract : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. READ MORE
