  1. 11. Rullflaskemetoden

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Ida Kellokoski Adamsson; [2014]
    Nyckelord :rullflaska; okulär bedömning; vidhäftningsförmåga; bildanalys och täckningsgrad; Technology and Engineering;

    Sammanfattning : Abstract Today large amounts of macadam are being delivered for the production of asphalt. One of the requirements of the material that´s being used is the adhesion. The adhesion is essential for the performance of the coating. It minimizes the risk of stone chips and makes the construction of the pavement stronger etc. LÄS MER

  3. 12. Rotationsviskosimeter, RVB

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Erik Nilsgart; Tobias Grybb; [2014]
    Nyckelord :bitumen; viskositet; rotationsviskosimeter; brookfield; sasobit; polymermodifiering; Technology and Engineering;

    Sammanfattning : To most people bitumen is an unknown material although it is the most important ingredient in asphalt pavements, something that everyone knows and uses every day. By merely distilling crude oil a substance is produced with unique properties and durability, which could not have been produced by synthetic means, at least not in those quantities used. LÄS MER

  4. 13. Dynamisk skjuvreometer för reologisk undersökning av bitumen

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Andreas Jansson; Anders Emanuelsson; [2013]
    Nyckelord :bitumen; dsr; reologi; komplex modul; fasvinkel; superpave; funktionell mätteknik; Technology and Engineering;

    Sammanfattning : The Rheology of asphalt binders is crucial for the function and durability of road pavements. In the American road concept Superpave, which has been in use for about 20 years, old empirical methods has been replaced with a rheological measurement technology in the form of DSR. LÄS MER

  5. 14. Evaluating surface energy components of asphalt binders using Wilhelmy Plate and Sessile Drop Techniques

    Master-uppsats, KTH/Väg- och banteknik

    Författare :Anohe Bahramian; [2012]
    Nyckelord :Asphalt binder; Adhesion; Surface energy; Bitumen surface;

    Sammanfattning : In this Study, the surface energy was investigated for six penetration grade 70/100 bitumen binders. Wilhelmy Plate and the Sessile Drop were used to determine the contact angles. LÄS MER

  7. 15. ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel

    Uppsats för yrkesexamina på grundnivå, Byggteknik

    Författare :Pontus Norrlander; [2012]
    Nyckelord :Bioasphalt; Biobitumen; Alternative asphalt pavements; Environmentally friendly asphalt; Bioasfalt; Biobitumen; Alternativa asfaltsbeläggningar; Miljövänlig asfalt;

    Sammanfattning : This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly. LÄS MER
