1. 1. 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

3. 2. A System Perspective on Energy End-Use Measures in a District Heated Region : Renovation of Buildings and Hydronic Pavement Systems

   Författare :Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Jan Akander; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A district heating and cooling (DHC) system can be a viable piece of the puzzle in the efforts of reducing the greenhouse gas (GHG) emissions. Especially if the DHC system include combined heat and power (CHP) plants which enable electricity production from renewable resources. LÄS MER

4. 3. Utilizing solar energy for anti-icing road surfaces using hydronic heating pavement with low temperature

   Författare :Raheb Mirzanamadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar energy; asphalt concrete; ground heat exchanger; anti-icing; optimization;

   Sammanfattning : During summer, the surface temperature of an asphalt road pavement can rise up to 70°C due to absorbed solar radiation. The high temperature degrades the performance of the asphalt concrete by accelerating the thermal oxidation and plastic deformation, especially under heavy traffic loads. LÄS MER

5. 4. Low temperature deicing of road infrastructure using renewable energy

   Författare :Josef Johnsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; borehole thermal energy storage; renewable energy; BTES; numerical simulations; Pavement solar collector; Hydronic heated pavements;

   Sammanfattning : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.
