  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. SuDS water storage capacity calculator : A decision support tool for the implementation ofSustainable Drainage Systems in Östersund.

    Master-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Tess van der Hulle; [2022]
    Nyckelord :Sustainable Drainage Systems SuDS ; Decision Support Systems DSS ; precipitation; calculator; stormwater model; Östersund; Sweden;

    Sammanfattning : Heavy precipitation events are expected to increase in intensity and frequency, due to global warming. Sewer systems might overload during heavy rainfall, resulting in floods which potentially affect all municipalities in Sweden. LÄS MER

  4. 3. Bullerreducerande beläggningar

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Max Filinic; [2020]
    Nyckelord :Lågbullerbeläggningar; bullerreducerande beläggningar; ansvarsform; ABD; teknisk och akustisk livslängd; stenlossning; Huskvarna; Flädie E6.02; Technology and Engineering;

    Sammanfattning : Bulleremission från vägtrafik är på många ställen i Sverige ett påtagligt problem. Många fastigheter och rekreationsområden ligger så nära vägnätet att de utsattas hälsa och livskvalitet riskerar att försämras vid långvarig exponering. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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. LÄS MER

  7. 5. Porous Asphalt Clogging Performance Under Swedish Conditions

    Master-uppsats, KTH/Byggvetenskap

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

    Sammanfattning : 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. LÄS MER
