  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. Transportation planning from asphalt manufacturing to paving : A case study in the asphalt sector

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Jezper Löfberg; Oscar Ling-Vannerus; [2022]
    Keywords : ;

    Abstract : The purpose of this thesis was to map and evaluate the current transportation flow for transportation of asphalt at a Swedish construction company in the asphalt pavement sector. The mapping and evaluation target the transportation methods together with the information and material flow. READ MORE

  4. 3. An investigation of detecting potholes with UAV LiDAR and UAV Photogrammetry

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Linus Hedenström; Sebastian Eriksson; [2021]
    Keywords : UAV; LiDAR; photogrammetry; potholes; point clouds; SfM; paved; pavement; road; drone; UAV; LiDAR; fotogrammetri; potthål; drönare; asfalt; väg; punktmoln; SfM;

    Abstract : Potholes are caused by erosion and as such always emerging on our roadnetwork. Potholes may not only cause great damages to vehicles, but can alsocause road accidents, which in the worst case are fatal. READ MORE

  5. 4. 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.

  6. 5. Kontroll av projekterade tjocklekar på sättlager och sätt- och fogmaterialets kornstorleksfördelning i överbyggnader i Malmö

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Daniel Isgren; [2020]
    Keywords : sättlager; fogmaterial; kornstorleksfördelning; överbyggnad; bärlager; halvelastisk beläggning; naturstenshällar;

    Abstract : Bärlagret är det översta bärande skiktet i överbyggnaden. När ytor belagda med naturstenshällar och markbetongplattor besiktigas används oftast endast okulär observation trots att beställaren har rätt ”utöva den kontroll över entreprenaden som han anser lämplig” (Byggandets kontraktskommitté , 2014).
