Consequences for road designs with regard to changes in temperature (English)
Abstract [sv]

SMHI:s data tyder på att temperaturen i Sverige kommer att öka. Dessutom kommer det framtida temperaturintervallet att vara mindre. Dessa två beräknade förändringar kommer att påverka den dimensioneringsprocess som idag används för vägar. Idag tar trafikverket hänsyn till temperaturen i ett bitumenbundet lager samt klimatperiodernas längder och båda dessa variabler kommer att förändras med tiden. Detta kommer att påverka val av material, materialåtgång vid nybyggnation, underhållsåtgärder samt vägens beräknade livslängd och kraven på de bitumen som skall används i framtiden. Förutom detta kan trafikverket behöva se över ett antal tabellvärden samt den klimatzonsindelning organisationen för närvarande använder sig utav.

Abstract [en]

The data from Sweden’s meteorological and hydrological institute suggests the temperatures in Sweden will rise in the future. It also suggests that the future temperature intervals will be smaller than they are today. This will affect the methods that are used for designing roads. Currently Trafikverket takes into account the temperature of the asphalt and the number of days of a specific climate period when considering climate temperature. Both these variables will have to be checked and possibly redone. This change will affect several areas that are important for the design, among these are the choice of materials, the amount of materials used, the cost of building and maintaining a road, a roads expected lifetime and the requirements for future asphalt layers. Add to that Trafikverket will probably need to recheck several table values and the climate zones that the organization uses today.
