dc.description.abstractThere is a continuous challenge to uphold the standard of Norwegian roads. As the volume of traffic is increasing, the roads are exposed to a bigger traffic load. On the basis of this, a study from Statens Vegvesen (Norwegian Public Roads Administration, hereinafter referred to as “SVV”) Region Midt was conducted, with focus on quality and the long-term building of roads. This report is therefore a contribution to a far greater work. In able to argue for a real project, the stretch between Fjerdingen – Grøndalselv has been used as basis. At this stretch, a part of an allotment of 11, 7 km is to be corrected, which is a part of the project E6 Grong – Nordland border. In totally, there has been deposited ca. 360 million NOK for the improvement of this specific allotment. In this study different factors that could contribute to the quality of the road during construction has been reviewed. Furthermore, there has also been looked upon how a greater focus on quality during construction, could contribute to a longer lifetime for the roads. In addition is advantages and disadvantages with building a new road and improving an old road compared. In order to gather information to the discussion part, literature study has been used, as well as interview. The objects of these interviews were employees at SVV who are working in different departments. The questions and answers will therefore vary, given that the persons being interviewed had different experiences from different fields of study. As all the interview objects were found within the same company, it should also be taken into account that the information might be somewhat unilateral in their perceptions. An important factor in roadconstruction is always cost. It has therefore been relevant that this factor has been taken into account during the discussion, without this being of crucial importance. This so other factors like quality and long-term would be deliberated in mainfocus. By the help from SSV’s standard price, the group developed an accounting over the expenses linked to the construction of a new road, as well as the improvement of an already existing road. The method Best Value Procurement emphasize the suppliers’ competence and presentation by help of project management and procurement. By using this method, the goal is to be able to give the assignments to the suppliers who hold the correct experience and in addiction put a greater focus on quality in the road construction. After the discussion part several results emerges, and has been important for the conclusion in this report. In order to achieve a road with the desired quality and durability, good conditions of the soil must be present. The choice of corridor can reduce great cost on a project and is affected by the roads’ appropriated capital, average daily traffic and location. The capital of the already existing road is largely a determinative factor for whether or not the existing road structure can be used. How much maintenance a road needs, is connected to the amount of traffic and the carrying capacity of the road. If damages on the pavement are continuously arising, there is generally the carrying capacity and strength of the road that is too poor. A broader road will provide better safety against oncoming traffic, as well as obstacles in its own lane. This is because it will provide better space for parallel displacement. The problems arising by weak or none frost protection are typical damages that will reduce the quality of the road, as well as the driving comfort. There are several moments that must be taken into consideration when choosing whether to correct a road, or build a new one. By choosing the latter, the advantages would be that one could achieve a higher quality on the road conditions, lower maintenance cost, longer lifetime expectancy and greater opportunities for design. However, it is still a costly and comprehensive process, which is time consuming in both engineering and embodiment. An improvement of the already existing road will be challenging due to greater uncertainty in relation to already existing road capital, greater risk for later damages and problems with movement of the road. The improvement will therefore be a far more reasonable solution, a shorter process and as such less time consuming. In conclusion, there is possible that the improvement of an already existing road will achieve an equivalent lifetime as the construction of a completely new road. However, it will demand more comprehensive and costly remediation process. It turns out that several measures increase the quality of the road, but not necessarily its lifetime. Further research should be conducted by comparing several projects, by obtaining a sufficient data base and considering challenges in relation to the climate and environment. In conclusion, it should also determine whether or not the conclusion of this study can be proven in larger projects.nb_NO
