Abstract
We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the savings, both economic and environmental, that could be made by optimizing material transport. To show this, calculations of real objects have been made in combination with qualitative interviews with people from the industry. The way in which transport is made today is not optimal.

We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the savings, both economic and environmental, that could be made by optimizing material transport. To show this, calculations of real objects have been made in combination with qualitative interviews with people from the industry. The way in which transport is made today is not optimal. When renewing the road-surface, the old milled asphalt material is being transported to the asphalt plant and newly manufactured asphalt back to the worksite. However, milled asphalt is being transported back to the plant with one set of trucks, and at the same time another set of trucks are transporting new asphalt back to the worksite. This mean that all vehicles are running empty in one direction. The results from this report have shown that the proposed improved method, which means that the same vehicles carrying both old material and newly made asphalt is very profitable both in economic and environmental terms when used at the ideal worksites. The definition of an ideal of worksite denotes those with longer transport lengths as well as those when guaranteed time payments are avoided through better use of each transport unit. In these cases, both the economic and environmental improvement can be up to 40 %. When interviewing people from the industry, it emerged that there are indeed a lot of technical problems to solve, mainly concerning the design of the vehicles. It was also discovered that there was a lot of interest for the proposed method, and results suggest that the method is not in any way impossible to implement. However, it would initially involve a lot of administration and planning. In order to implement this method, it would initially require higher compensation to the haulage companies, mainly because of the increased costs in form of more wear on the vehicles as well as higher fuel consumption, which leads to the more efficient use of the vehicles loading capacity. This additional compensation would also serve as a bonus to make the haulers themselves more motivated in developing more adapted vehicles. (Less)
