2. 1. Life Cycle Assessment of Asphalt Roads : Decision Support at the Project Level

   Author : Ali Azhar Butt; Björn Birgisson; Nicole Kringos; Susanna Toller; Stephen T. Muench; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt roads; life cycle assessment; feedstock energy; warm mix asphalt additives; green procurement; decision support; laboratory investigation; pavement design.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

   Abstract : Transport infrastructures such as roads are assets for the society as they not only ensure mobility but also strengthen society’s economy. Considerable amount of energy and materials, that include bitumen, aggregates and asphalt, are required to build and maintain roads. READ MORE

4. 2. Sustainable Implementation of Electrified Roads : Structural and Material Analyses

   Author : Feng Chen; Niki Kringos; Andreas Loizos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrified road; Structural performance; Constitutive modelling; Asphalt; Dielectric loss.; Elektrifierade vägar; Strukturellt beteende; Konstruktivt modellerande; Asfalt; Dielektrisk förlust.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

   Abstract : Given the promise of the Inductive Power Transfer (IPT) technology for eRoad applications, the potential challenges for a successful integration of dynamic IPT technology into the physical road structure are explored extensively in this research work. The Finite Element Method (FEM) is selected for studying the structural performance of an eRoad under operational conditions. READ MORE

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

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

   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

6. 4. Towards frost damage prediction in asphaltic pavements

   Author : Lisa Lövqvist; Nicole Kringos; Romain Balieu; Robert Karlsson; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Mechanistic-Empirical Modeling of Permanent Deformation in Asphalt Concrete Layers

   Author : Erik Oscarsson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; modeling; Mechanistic-Empirical; rutting; asphalt concrete; full-scale pavements;

   Abstract : Three mechanistic-empirical permanent deformation models were evaluated under Swedish conditions with respect to traffic, climate and materials using accelerated pavement testing and long-term pavement performance studies. The mechanistic-empirical pavement design guide (M E PDG), the incremental-recursive mechanistic-empirical CalME model (CalME), and the PErmanent Deformation of asphalt concrete layer for ROads (PEDRO) model generally showed both useful features and limitations.
