Abstract [en]

The continuous growth in road transportation demand requires the development towards

sustainable strategies. The concept of Smart Roads is arising as a convergence of technologies

that will lead the mobility by road into a more efficient and interactive system between

infrastructure, environment and vehicles. Within this context, e-mobility appears as one of the

key components.

The implementation of e-mobility based on Electric Vehicles (EVs) has been restricted by

numerous shortcomings such as their driving range, the battery size, the dependence on

charging stations and the time required for its charging. However, the electrification of the

road infrastructure, which will enable a dynamic charging of the EVs while driving, is

becoming a potential solution to overcome these deficiencies.

This study aims to contribute for the future introduction of electrified roads (eRoads) into the

current network, by focusing on the effects and consequences of embedding Inductive Power

Transfer (IPT) systems in the road infrastructure. A structural design of an eRoad is

conducted through a Finite Elements Analysis (FEA) by analysing the behaviour of a

pavement structure based on Swedish conditions subjected to traffic loading. Valuable

conclusions can be displayed from this analysis and thus, a summary concerning

considerations and effects over the design, construction and maintenance of eRoads can be

built. Nevertheless, this analysis must be complemented and coordinated from a lifetime

perspective to reach the social, environmental and economic requirements related to the

development of road infrastructure nowadays. Hence, a guideline from a life cycle approach is

stated over the integration of eRoads in order to enable the assessment of the infrastructure

during its different phases.

To be sustainable, the development of road infrastructure must reach not just structural and

appropriate performance requirements, but also preserve the environmental and economic

impact. This thesis pretends to combine all these aspects as a state of the art, providing a basis

that stands out the most relevant issues related to the feasible implementation of eRoads in the mid-long term.
