  1. 1. Assessment of aggregate structure in porous asphalt using X-ray computed tomography

    Master-uppsats, KTH/Väg- och banteknik

    Författare :Mari Haagenrud Matsson; Malex Love Valdemar Åkerblom; [2023]
    Nyckelord :Tomography; non-destructive testing; destructive testing; air voids content; aggregate size distribution; porous asphalt;

    Sammanfattning : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

  3. 2. DELAMINATING PAINT IN AN 18TH CENTURY CANVAS WALL PAINTING A Case Study at the von Echstedt Manor

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Lisa Bandgren; [2021-10-28]
    Nyckelord :Delaminating Paint; Canvas Wall Paintings; Material Analysis;

    Sammanfattning : This study investigates the cause and progression of the ongoing deterioration in a canvas wall painting from the 1760s in the Green Chamber at the von Echstedt manor. In an area approximately 170 x 170 cm on the south wall, the paint is severely delaminating despite several attempt to consolidate it. LÄS MER

  4. 3. Determination of thermal conductivity for mastic asphalt by combining previously performed laboratory work and TASEF

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Martin Kruse Lindgren; [2021]
    Nyckelord :Mastic asphalt; BPGJA-11; thermal conductivity; TASEF; FEM; Timber; Gjutasfalt; BPGJA-11; termisk konduktivitet; TASEF; FEM; Trä;

    Sammanfattning : Mastic asphalt is a material which in Sweden mainly is used as coating for bridges, parking decks, courtyards and terraces. Mastic asphalt is a material built-up by a combination of bitumen (a type of binder), well-graded aggregate (consists of both coarse and fine ballast), filler, sand and sometimes also fine graded macadam.

  5. 4. Investigation of Air Void Structure in Double Layer Porous asphalt based on X-ray Computed Tomography

    Master-uppsats, KTH/Byggvetenskap

    Författare :Shuchen Gong; [2020]
    Nyckelord :Tomography; non-destructive testing; destructive testing; air voids content; porous asphalt drilled cores;

    Sammanfattning : The X-ray computed tomography is a technology to investigate air void structure of drilled asphalt cores, which provides a non-destructive alternative to traditional laboratory methods, usually destructive testing.In this work, six in-situ specimens from a double layer porous asphalt pavement in Linköping, Sweden, were taken and analysed using both qualitative and quantitative methods of tomography.

  7. 5. The myths and hazardous life of asphalt labourer : A pre-study on work environment and gender equality in the asphalt paving industry

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Pipar Julia Bahri; [2020]
    Nyckelord :Asphalt; road construction; male-dominated industries; safety work; gender equality; microwave heater; attractive workplace; Asfalt; vägarbete; mansdominerade industrier; säkerhetsarbete; jämställdhet; mikrovågsvärmare; attraktiva arbetsplatser;

    Sammanfattning : Road construction work is often regarded to be a dirty and strenuous job. The asphalt paving industry is male-dominated with a low percentage of women. This master thesis is part of Human Work Sciences at Luleå University of Technology's participation in the SMMART (Swedish Magnetite Microwave Asphalt Road Technology) project. LÄS MER
