  1. 1. Ligninn i bindemedel för hållbara asfaltbeläggningar. Reologiska undersökningar

    Master-uppsats, Lunds universitet/Trafik och väg

    Författare :Nikola Maka; Luan Imeri; [2021]
    Nyckelord :lignin; asphalt binders; DSR; RVB; sustainability; Technology and Engineering;

    Sammanfattning : Bio-based binders have recently been introduced to reduce the dependence on fossil raw materials, which bitumen is produced of. Measurements with dynamic shear rheometer (DSR) and rotational viscometer (RVB) were performed on mixtures with bitumen and two different types of bio-based binders, namely Lignin 1 and Lignin 2.

  3. 2. Förbättring av asfaltens konsistens med tillsatsmedel - Mätningar med rotationsviskosimeter på bitumen och asfaltsbruk

    Kandidat-uppsats, Lunds universitet/LTH Ingenjörshögskolan vid Campus Helsingborg

    Författare :Martin Bakalov; Arwa Shukir; [2017]
    Nyckelord :bitumen; föryngringsmedel; återvinning; asfalt; återanvändning; asfaltbruk; tillsatsämnen; Technology and Engineering;

    Sammanfattning : Asphalt is the most common material on the roads visible to our eyes. Asphalt occurs as both wearing coat and bearing coat. Asphalt consists of rock material in different grain sizes joined by a binder, bitumen, and eventually added additives. Bitumen is extracted from crude oil. LÄS MER

  4. 3. 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

  5. 4. Dynamisk skjuvreometer och kompletterande metoder för bitumenundersökningar

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Khalid Kamil; Henrik Jakobsson; [2014]
    Nyckelord :dsr; dynamisk skjuvreometer; bitumen; sasobit; polymermodifierat; mscr; kryptest; reologi; superpave; Technology and Engineering;

    Sammanfattning : Increasing heavy traffic on the roads raises demands on pavements and especially the binder of the pavements. The rutting and other deformations resistances are constantly improved. As a part of the development wax mixes and polymer modified variants are produced. LÄS MER

  7. 5. Optimal Tempererad Asfalt - OTA - en undersökning av asfalt med Sasobit

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Johan Lund; Azur Kujundzic; [2012]
    Nyckelord :asfalt; sasobit; vax; stabilitet; bitumen; viskositet; Technology and Engineering;

    Sammanfattning : The concept of OptimalTempered Asphalt, OTA, stands for the best temperature all aspects considered for the bitumen and the manufacturing process as well as the end-product. This is achieved in various ways using additives, choice of manufacturing procedure and changing mixture of asphalt. LÄS MER
