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

    University essay from KTH/Väg- och banteknik

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

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

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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.

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

    University essay from KTH/Byggvetenskap

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

    Abstract : 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.

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

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

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

    Abstract : 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. READ MORE

  6. 5. The effect of filler type and shape on HMA energy dissipation performance.

    University essay from KTH/Väg- och banteknik

    Author : Yohannes Gebremeskel Kiflat; [2013]
    Keywords : Hot mix asphalt; mastic; fillers; compaction energy index; superpave;

    Abstract : Hot mix asphalt pavements require adequate compaction to achieve the required density to resist rutting. The amount of energy required to achieve the optimum degree of compaction depends on the type of gradation, bitumen content, filler type and shape, type of compaction equipment etc. READ MORE
