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

    University dissertation from Chalmers University of Technology

    Author : Raheb Mirzanamadi; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road; slippery condition; asphalt concrete; energy harvesting; thermal properties; finite element method; anti-icing; hydronic heating pavement;

    Abstract : 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. READ MORE

  3. 3. Measurements for winter road maintenance

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mats Riehm; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; winter road maintenance; sensors; infrared thermometry; energy efficiency; road salt;

    Abstract : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl). READ MORE

  4. 4. Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lina Nordin; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Road climate; RWIS; frost; snow; fuel consumption; heavy-duty vehicles; route optimisation programme; energy efficiency; winter road maintenance;

    Abstract : Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency potentials in the different aspects of the road maintenance area. READ MORE
