16. Sustainable Implementation of Electrified Roads : Structural and Material Analyses
Sammanfattning : 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. LÄS MER
17. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide
Sammanfattning : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. LÄS MER
18. Harvesting in the boreal forest on soft ground : ways to reduce ground damage
Sammanfattning : The overall aim of the studies underlying this thesis has been to acquire knowledge relating to potential methods of reducing both the amount and severity of ground damage caused by forest machinery used in the boreal forest. The work focused on technical solutions applied to the forwarders that had the potential to reduce ground damage such as rutting and soil compaction. LÄS MER
19. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests
Sammanfattning : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

20. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives
Sammanfattning : Roads are assets to the society and an integral component in the development of a nation’s infrastructure. To build and maintain roads; considerable amounts of materials are required which consume quite an amount of electrical and thermal energy for production, processing and laying. LÄS MER
