  2. 1. Development of a Morphology-based Analysis Framework for Asphalt Pavements

    Author : Ibrahim Onifade; Björn Birgisson; Nicole Kringos; Denis Jelagin; William G. Buttlar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; damage; X-ray computed tomography; top-down cracking; fracture; Morfologi; skador; röntgendatortomografi; ’top-down’sprickbildning; fraktur; Byggvetenskap; Civil and Architectural Engineering; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The morphology of asphalt mixtures plays a vital role in their properties and behaviour. The work in this thesis is aimed at developing a fundamental understanding of the effect of the asphalt morphology on the strength properties and deformation mechanisms for development of morphology-based analysis framework for long-term response prediction.

  4. 2. Reliability-based Design Procedure for Flexible Pavements

    Author : Yared Hailegiorgis Dinegdae; Björn Birgisson; Nicole Kringos; Nils Rydén; William Buttlar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Top-Down fatigue cracking; asphalt mixture morphology; fracture mechanics; response surface; reliability analysis; load resistance factor design; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This failure mode has been observed in many parts of the world, and in some regions, it was found to be more prevalent and a primary cause of pavements failure. READ MORE

  5. 3. Mechanics-based Design Framework for Flexible Pavements

    Author : Yared H. Dinegdae; Björn Birgisson; David Newcomb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanics-based; asphalt; fatigue; reliability; traffic; variability; Mekanik-baserade; utmattningssprickor; pålitlighet; lastbilstrafiken; variabilitet; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This paper presents a mechanics-based design framework in load and resistance factor design (LRFD) format for the top-down fatigue cracking performance evaluation of flexible pavements. READ MORE
