This report is the first step in a doctoral project related to optimisation of the functional properties of concrete roads with respect to public factors. The aim of the report is to survey and quantify the relationships between the different properties. These will subsequently establish the bases for further research. _x000D_ _x000D_ Concrete is a suitable material for road pavements, both technically and economically. That holds especially for roads with great traffic intensity and heavy loads. High wear resistance and loadbearing capacity, good durability and a light surface are some of its advantages. _x000D_ _x000D_ A survey of the different properties have given the following: _x000D_ _x000D_ Concrete pavements are very wear resistant which results in small rutting. The experiencies from the concrete roads outside Falkenberg and Arlanda confirm this. Despite of this good results, it is eaven possible to build two to three times more wear resistant concrete pavements then has been done so far. The results from Falkenberg are so good that maintenance because of rutting will not be necessary during the 35-40 years to come. Concrete roads are normally maintenanced for rutting after 15-20 years. Comparable asphalt pavements outside Falkenberg and Arlanda have also shown good results, but they are not as good as those for the concrete pavements. It shall be noted that the used asphalt pavements were optimized with regard to wear resistance. _x000D_ The smoothness of the road surface is important for the riding comfort. Today, it is possible to obtain equal or better smoothness with a concrete pavement than with an asphalt pavement. _x000D_ Earlier, transverse texture was used to obtain a good friction. With respect to the noise levels, there has been a change to other textures such as longitudinal textures or exposed aggregates. Even with this kind of surface treatments, it is possible to achieve high friction values. This means that there is no contradiction between high friction and low noise level. _x000D_ The brightness of the pavement has a great importance for the traffic saftey and the sight comfort for the road-users. Besides that, it influences the costs for investment, operation and maintenance of the lighting plants. Concrete pavements has high brightness, even initally, and the value is almost twice as high as for asphalt pavements. _x000D_ Concrete pavements traditionally have had higher noise levels than asphalt pavements. But the change to longitudinal texture and the development of new concrete surfaces have led to that it today is possible to build concrete roads with similar noise levels as for asphalt surfaces. Concrete roads with exposed aggregates and maximum grain size 8 or 16 mm lower the noise levels and this method is very common in Europe. _x000D_ There are studies showing that concrete pavements have lower rolling resistance, which in turn leads to lower fuel consumption for the road-users. The greatest difference in fuel consumption between different materials is obtained for heavy vehicles such as trucks and buses. Measurements have showed differencies of up to 20 % between different materials for trucks and buses and 9 % for private cars. The disadvantage of aspalt pavements is that they also deform which leads to an increase in fuel consumption, foremost for heavier vehicles. _x000D_ During the concrete production, the environment is most influenced by the effects from the cement production. The environmental problems during the maintenance period are often related to particles due to wear of the pavement from the traffic. The dust can also effect human health. Concrete can be recycled and used as a road material or as aggregates in new concrete. Recycling of concrete is very common in several countries. _x000D_ The riding comfort is depending on the surface texture and the quality of the pavement. For the road users, a good riding comfort is often defined as a good car standard in combination with a good road standard. _x000D_ Life cycle costs (LCC) of road pavements show that in a long time perspective concrete pavements are often more economically than asphalt pavements. _x000D_ The results from life cycle analasys (LCA) for roads, including traffic, show that the fuel consumptions stands for 90 % of the road´s total impact on the environment. Lightning (5 %) and the pavement material (5 %) stand for the rest of the environmental impact. The results from the conducted LCA of roads show that concrete pavements have equal or lower impact on the environment than asphalt pavements. _x000D_ When the relationships between the different properties are surveyed, the bases is established for the optimisation process. A first suggestion for a optimisation model has been processed in this report. The model will then be used as a basis for the continuing work. _x000D_ _x000D_ For futher research, the following topics are of interest: brightness, fuel consumption, dust and health and economical/environmental impact of the different properties. _x000D_
