1. Assessment of aggregate structure in porous asphalt using X-ray computed tomography
Master-uppsats, KTH/Väg- och banteknikSammanfattning : 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.

2. Determination of thermal conductivity for mastic asphalt by combining previously performed laboratory work and TASEF
Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : 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.

3. Investigation of Air Void Structure in Double Layer Porous asphalt based on X-ray Computed Tomography
Master-uppsats, KTH/ByggvetenskapSammanfattning : 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.

4. 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 samhälleSammanfattning : 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
5. Metodik för utmattning av asfaltbruk
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och vägSammanfattning : The durability of asphalt can be investigated with fatigue tests, which unfortunately are very laborious and costly. Therefore, they are not used as often as they should. At LTH in Lund, an alternative method is utilized using a dynamic shear rheometer, DSR, on asphalt’s mastic for fatigue properties testing.
