  3. 22. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations

    Författare :Raheb Mirzanamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal properties; slippery condition; hydronic heating pavement; energy harvesting; asphalt concrete; road; anti-icing; finite element method;

    Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER

  4. 23. Subsurface Environmental Impact in Urban Areas. Shallow Groundwater Composition, Corrosion of Soil-Buried Constructions, and Leachates from Reclaimed Asphalt Pavement

    Författare :Malin Norin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GC MS screening; soil-buried constructions; subsurface urban environment; shallow groundwater quality; corrosion; reclaimed asphalt pavement;

    Sammanfattning : Worldwide, groundwater represents the largest and most important source of potable water. Usually, urbanisation affects shallow urban aquifers in two ways: by radically changing patterns and rates of aquifer recharge, and by adversely affecting the quality of groundwater. LÄS MER

  5. 24. 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

  7. 25. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models

    Författare :Sven Agardh; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore technology; Civil engineering; hydraulic engineering; Teknik; Technological sciences; PM-system; deterioration models; rutting; pavement design; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. LÄS MER
