  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. 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.

  4. 3. Porous asphalt as a method for reducing urban storm water runoff in Lund, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gea Hallen; [2017]
    Keywords : PCSWMM; urban flood modelling; porous asphalt; Physical geography and Ecosystem Science; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Flooding is a major risk to the ever increasing urban population, posing a threat to human lives but also causing traffic interruptions, economic losses and pollution. Built up areas are prone to flooding due to the changes of previously pervious surfaces being covered by buildings and impervious pavements, such as asphalt. READ MORE

  5. 4. Porous Asphalt Clogging Performance Under Swedish Conditions

    University essay from KTH/Byggvetenskap

    Author : Fuad Ahmed; [2015]
    Keywords : Air voids; clogging; noise; porous asphalt; X-ray; maintenance; Hålrum; igensättning; buller; bullerreducerande beläggning; tomografi; rengöring;

    Abstract : Porous asphalt has gradually gained a lot of popularity in the past ten years for its ability to reduce traffic noise, especially noise generated between tire and road surface. The acoustical absorption properties are mainly due to the pore structure and the texture of the mixture. READ MORE
