### Construction
The coils may be deposited in two different ways: an in-situ method and a pre-cast solution. The pre-cast solution implies that the coils arrive at the site already embedded in their low-stiffness concrete boxes. Using a pre-cast system in this situation might be preferable as there would be no need to wait for the concrete to set compared to the case where the coils are inserted in situ. This means that the asphalt layer could be laid immediately, thus reducing construction times. The use of extendible trailers with a crane for the installation of pre-cast concrete tram tracks was considered for this solution. The technical data of a commercially available trailer crane was used to model the use of a trailer. Once the boxes containing the coils have been installed, they are again covered with binder and wear layers. The repaving procedure involves the following steps:  
* A paver distributes asphalt over the lane, ensuring that the full width of the lane is covered. * A roller then compacts the asphalt to make the thickness and compaction uniform. More than one passage is usually required to obtain the desired compactness. * The application of an emulsion linking layer over the binder: An adequate joining coat is necessary between the road layers to ensure a longer life of the e-road structure. This connection may be done with a bituminous emulsion. In order to obtain the fuel consumption for the reconstruction of the lane after the WPT module has been embedded, a paver with an operating width of 3.75 m was considered (power 130 kW, weight 19 t). The consumption of diesel depends on the quantity of asphalt that has to be paved, and on the thickness of the layers. The speed of the paving machine for a 6 cm thick layer is 1028.8 m\({}^{2}\)/h and the hourly fuel consumption is 23.2 L/h. A paving machine with a 1.4 m operating width and a weight of 6.4 t was selected for the binder layer. Its clearance width of 1.4 m allows the two lateral areas to be covered, without damaging the coils. A paving speed of 30 m/min and a nominal power of 55.4 kW were considered. As the hourly consumptions were not available, they were derived from the consumption of the larger paving machine, assuming a linear relationship between power and consumption. A roller machine with a roller width of 2 m was chosen for the compaction of the wear layer. Another roller with an operating width of 1.5 m was considered for the binder layer. The fuel consumptions of the aforementioned machinery are reported in Table 6.  
The larger roller has to repeat the rolling twice, for both the binder and the wear layers, in order to cover the full width of the lane. The slimmer roller was selected for the binder, as it has to pass along the lane twice, without pressing the coils. For precautionary reasons, the same fuel consumption was assumed for each passage, even though the consumption decreases as the compaction of the layers grows. The quantities can be set at the typical value of 0.6 kg/m\({}^{2}\) for the bituminous emulsion layer [24]. An emulsion spraying machine is used to spray bituminous emulsion, which acts as a binder between the wear and binder layers. The considered machine had a power of 265 kW and an operation width of 4 m (see Table 6). The operating speed was 20 km/h and the hourly fuel consumption was 8.3 L/h.
