  1. 1. The Future of Smart Road Infrastructure : A Case Study for the eRoad

    Author : Feng Chen; Nicole Kringos; Björn Birgisson; Angelos Amditis; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : In the future, physical roads will not only serve for the mobility of the vehicles but also have the capability of enabling different smart functionalities, such as car2road communication, energy harvesting or dynamic charging of electrical vehicles. To ensure the sustainability of these advances, the environmental, economic and social costs for the road infrastructure itself should not offset its possible advances. READ MORE

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

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

    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

  3. 3. A blueprint for sustainable consumption and design including performance requirements

    Author : Martin Erlandsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : A Sustainable Consumption Evaluation(SCE) system framework is developed which is based on anextension of current LCA methodology. The SCE system results inEnvironmental Performance Requirements(EPR's) as the key means for its implementation insustainable design that can be used for product orproduct-service system benchmarking, monitoring and evaluation.

  4. 4. Internal Erosion Phenomena in Embankment Dams : Throughflow and internal erosion mechanisms

    Author : Farzad Ferdos; Anders Wörman; Bijan Dargahi; Fredrik Johansson; Willi Hager; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal erosion modelling in porous material; Constitutive law of erosion for closure of continuum-mechanics-based balance equations for numerical modelling; High Reynolds-number turbulent flow; Flow laws; Coarse rockfill material throughflow; Computational Fluid Dynamics.; Civil and Architectural Engineering; Byggvetenskap;

    Abstract :  In this study, two major internal erosion initiation processes, suffusion and concentrated leak mechanisms, which lead to both defect formation in a dam’s body and its foundation and high throughflow in dams subjected to internal erosion were studied. This understanding has the potential to facilitate numerical modelling and expedite dam safety assessment studies. READ MORE

  5. 5. Towards the enhanced applicability of cold mix asphalt: : An experimental study focusing on surface free energies and the breaking and coalescence of bitumen emulsions

    Author : Abdullah Khan; Nicole Kringos; Per Redelius; Andreas Loizos; KTH; []
    Keywords : Bitumen; Cold Asphalt Mixtures; Minerals Aggregates; Surface Free Energy; Sorption; Contact Angle; Bitumen Emulsions; Breaking and Coalescence; Emulsifiers; Adhesion Promoters.; Bitumen; kallblandad asfalt; mineraler aggregat; fri ytenergi; sorption; kontaktvinkel; Bitumenemulsioner; brytning och koalescensen; emulgatorer; adhesionsegenskaper; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the road-engineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. READ MORE
