  1. 1. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen : Characterization and Modelling

    Författare :Jiqing Zhu; Niki Kringos; Dallas Little; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

    Sammanfattning : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. LÄS MER

  3. 2. Towards a Viscoelastic Model for Phase Separation in Polymer Modified Bitumen

    Författare :Jiqing Zhu; Niki Kringos; Jean-Pascal Planche; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer modified bitumen; storage stability; viscoelastic phase separation; PMB model; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : In this thesis, a review is given on the most popular polymers used today for polymer modification of bitumen. Furthermore, the development of a model for phase separation in polymer modified bitumen (PMB) is proposed, that will enable a better control and understanding of PMB phase behaviour, allowing thus to enhanced long-term performance.

  4. 3. Morphology of Polymers - Development of Electron Microscopy Methods

    Författare :Helen Hassander; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; polymer; electron microscopy; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. LÄS MER

  5. 4. Sample preparation effect on measured rheological properties of bitumen using Dynamic Shear Rheometer

    Författare :Maya Sheidaei; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bitumen rheology; dynamic shear rheometer; complex modulus;

    Sammanfattning : Through improved bitumen characterization, which will increase the road'sdurability, stability, and performance, pavement engineering can apply thesustainability notion that should be followed in all disciplines nowadays. The newtechniques distinguish between the rheological properties of bituminous binders as a function of loading time and temperature to depict real-world behavior rather than only considering empirical properties.

  7. 5. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives

    Författare :Ali Azhar Butt; Björn Birgisson; John Harvey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment; feedstock energy; asphalt binder additives; mass-energy flows; bitumen healing; wax; polymer;

    Sammanfattning : Roads are assets to the society and an integral component in the development of a nation’s infrastructure. To build and maintain roads; considerable amounts of materials are required which consume quite an amount of electrical and thermal energy for production, processing and laying. LÄS MER
