  1. 11. Investigations of binder rejuvenation related to asphalt recycling

    Author : Robert Karlsson; KTH; []
    Keywords : bitumen; rejuvenator; diffusion; ageing; aging; asphalt recycling; FTIR-ATR; RAP; structural stability; Hansen solubility parameters;

    Abstract : Investigations described in this doctoral thesis concernmaterial behaviour related to asphalt recycling. More indetail, the thesis describes development and application ofmethods for characterisation of the rejuvenation process, inwhich old and new binders are mixed. READ MORE

  3. 13. Towards frost damage prediction in asphaltic pavements

    Author : Lisa Lövqvist; Nicole Kringos; Romain Balieu; Robert Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frost damage; winter damage; asphalt; pavements; micromechanical model; microstructure; freeze-thaw cycles; finite element model; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Roads are subjected to mechanical loads from the traffic as well as deteriorating mechanisms originating from the surrounding environment and climate. The damage arising is particularly severe during the winter season, when for example raveling, pot holes and cracks can emerge on the surfaces of asphaltic roads. READ MORE

  4. 14. Resonance Testing of Asphalt Concrete

    Author : Anders Gudmarsson; Nils Rydén; Björn Birgisson; Mihai Marasteanu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance frequencies; Modal testing; Frequency response functions; Cyclic loading; Tension-compression tests; Complex modulus; Complex Poisson’s ratio;

    Abstract : This thesis present novel non-destructive laboratory test methods to characterize asphalt concrete. The testing is based on frequency response measurements of specimens where resonance frequencies play a key role to derive material properties such as the complex modulus and complex Poisson’s ratio.

  5. 15. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction

    Author : Jens Bergenudd; Jean-Marc Battini; Roberto Crocetti; Patricia Hamm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic analysis; Modal analysis; Pedestrian bridge; Timber; Railings; Asphalt; Slip modulus; Finite element modelling; Dynamisk analys; Modal analys; Gång- och cykelbro; Trä; Räcken; Asfalt; Förskjutningsmodul; Finita element modellering.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. READ MORE
