  1. 1. Ground freeze-thaw, snow and roads in northern Sweden

    University dissertation from Uppsala : Kulturgeografiska institutionen

    Author : Maria Sarady; Uppsala universitet.; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ground freeze-thaw; snow depth; roads; northern Sweden; geography; Geography; Geografi;

    Abstract : In this thesis freeze-thaw along roads in northern Sweden is examined. The examinations are put in a context of changing climate and its amplification towards the Arctic region on earth. The research focuses on the impact of a warmer climate on ground freeze-thaw and in exten- sion road maintenance in the region. READ MORE

  2. 2. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    University dissertation from Uppsala : Kulturgeografiska institutionen

    Author : Bo Li; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; chloride; concrete; freeze-thaw cycles; water uptake; chloride profile; frost action; transport;

    Abstract : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. READ MORE

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  5. 5. Compaction and thaw deformation of frozen soil permeability and structural effects due to freezing and thawing

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Peter Viklander; Luleå tekniska universitet.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : This thesis is the result of the two projects:"Deformations in winter compacted soils" and "Permeability changes in a fine-grained till due to freeze/thaw". The aim of the first project was to study whether it is possible to compact frozen soils, in road embankments etc. READ MORE
