| Abstract: | Rijkswaterstaat has given Witteveen+Bos the assignment to widen parts of the A58 from two to three lanes and to start the plan elaboration. This must be done in an innovative way and therefore all possible innovative applications that can be implemented at the A58 need to be considered. Two of these applications are the asphalt collector and the solar road. The aim of this thesis is to give Witteveen+Bos and Rijkswaterstaat insight in the potential of the asphalt collector and solar road on the A58 in the study area. To reach the aim, the main question of the thesis is formulated as followed: What is the potential for applying the asphalt collector and solar road on the A58 within the study area? The asphalt collector is a way to collect heat out of the asphalt and the solar road is a road covered with photo-voltaic cells. To give an answer to the main question, information out of literature and several interviews have been used, also geospatial data have been analysed. The technical conditions of the asphalt collector and solar road have been discussed first. The most important findings out of this are that the presence of an aquifer and the distance to the heat consumer is largely determining the potential of the asphalt collector and the costs, efficiency, strength and driving comfort are largely determining the potential of the solar road. After the technical conditions were discussed, an overview of the pros and cons has been given. The largest pro for both the asphalt collector and the solar road is that when they are implemented, the road has been given an extra function, not only transporting but also generating sustainable energy. The largest cons of the asphalt collector are the possible threat of losing an important heat consumer and that there is always a large number of involved parties what makes it difficult who is going to be in charge of the collector. For the solar road the largest cons are its costs and that it is hard to deal with the decrease in transparency of the top layer. From the above-mentioned and the effect of the asphalt collector and solar road on the technical conditions of the A58 the best potential implementation for both applications is determined. For the asphalt collector that is to use the Pipes-In-Asphalt collector at 5 lanes of 571 meter on the A58 close to the Sint Elisabeth hospital. The best potential implementation for the solar road on the A58 is to use the application that is used by Pavenergy at 2.1 km of emergency lane. From this research can be concluded that there is potential for applying the asphalt collector on the A58 within the study area because of the suited location and the ability to give the road two functions. On the other hand, there is not much potential to implement the solar road on a large scale when the A58 will be widened because of its high costs. A pilot project on a small scale to test the performance of the solar road on the Dutch highway has potential when there is support from subsidy. |
