  1. 1. An Ontology-Based Platform for Information Integration : Supporting Sustainable Smart Transportation Infrastructure

    Författare :Wiebke Belitz-Hellwich; Nicole Kringos; Annika Gram; Romain Balieu; Vangelis Angelakis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ontology; Semantic Web; Interoperability; Information Integration; Logistics; Simulation; Smart Port; ontologi; semantisk webb; interoperabilitet; informationsintegration; logistik; simulering; smart hamn.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Transportation and transportation infrastructure are major contributors to global emissions. Even though most of these emissions can be attributed to fuel consumption of vehicles, some of it is due to pavement construction and maintenance. LÄS MER

  3. 2. Towards a sustainable road infrastructure in an age of digitization: opportunities and challenges

    Författare :Zhuhuan Liu; Nicole Kringos; Romain Balieu; Aikaterini (Katerina) Varveri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable infrastructure; Pavement Maintenance; Optimization; Neutron tomography; Self-healing; Hållbar infrastruktur; Vägunderhåll; Optimering; Neutronavbildning; Självläkning; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : Pavement system plays an indispensable role in the socio-economic and sustainable development of every modern society. Yet, pavement construction and maintenance is also responsible for a significant fraction of the GHG emissions from the whole transport sector. LÄS MER

  4. 3. A multiscale approach for predicting freeze-thaw damage in asphalt mixtures

    Författare :Lisa Lövqvist; Nicole Kringos; Romain Balieu; Markus Oeser; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggvetenskap; Civil and Architectural Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : Cold and wet climates are a known threat to asphalt pavements, causing both an embrittlement of the material, making it more prone to failure, and increasing the risk of damage due to the presence of moisture in the material and freeze-thaw cycles causing expansion and contraction of the air voids as the moisture inside them freezes and thaws. This damage evolution can lead to an overall decrease of material properties and ultimately showcase itself as raveling, pot holes,and cracks. LÄS MER

  5. 4. Towards frost damage prediction in asphaltic pavements

    Författare :Lisa Lövqvist; Nicole Kringos; Romain Balieu; Robert Karlsson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Investigation on the self-healing capabilties of asphaltic materials using neutron imaging

    Författare :Adrian Markari; Nicole Kringos; Anders Kaestner; Romain Balieu; Lily Poulikakos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-healing; bituminous materials; neutron imaging; sample size effect; reconstruction; image processing; volumetric analysis; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : Bitumen acts as a binding agent in asphalt mixtures where it binds the aggregates together. It is known for its potential to heal small cracks and recover its mechanical properties under the right conditions. Though this self-healing property is known, there is currently a lack of knowledge about the mechanisms that drive the process. LÄS MER
