Future Trends in Sustainable Asphalt Materials and Emission Reduction in Nordic Countries

DESCRIPTION

This article explores the increasing focus on environmental considerations in asphalt production and its impact on sustainability. With 60% of emissions linked to materials, Nordic countries like Iceland, Denmark, Norway, Finland, and Sweden are implementing life cycle assessments and requiring eco-friendly practices from contractors. Recent initiatives such as the introduction of bonuses for low-temperature asphalt production signal a shift towards tackling CO2 emissions. As the demand for environmentally certified materials rises, the construction industry is poised to adopt greener technologies and processes.

  15. Flere udbud hvor asfaltentreprenørernes miljøprofil er et af tildelingskriterierne

  16. Krav til at entreprenøren er: • miljø- og arbejdsmiljøcertificeret • tilbyder miljøvenlige produkter/belægninger udlægningsprocesser • har en formaliseretmiljøvurderingsproces

  17. Rullemodstand: endnu ikke et centralt tema for danske belægninger

  18. Endnu kun ganske få udbud, hvor WMA har været omtalt.

  19. Miljøvurderingværktøjer kun været anvendt i meget begrænset omfang.

  21. 2013 sesongen: Statens vegvesen har innført en bonus for å produsere lavtemperaturasfalt med skumteknikker.

  22. Bonus på 30 kr pr tonn for faktisk lagt asfalt som produseres ved temperatur minst 25oC lavere enn normal temperatur

  24. Eftersom gammal asfalt klassificeras som avfall, så får inte asfaltavfall användas obundet i markbyggnadarbeten i Finland.

  25. LTA-tekniken har ännu låg volym. Inga krav eller «morötter» från beställare eller myndigheter har getts för att befrämja LTA-tekniken.

  26. En viss konservatism och fastlåsta attityder

  27. Man förväntar sig att LTA-beläggningar ökar i framtiden

  28. Under 2000-talet har mera fokus lagts på CO2-utsläpp.

  29. I Finland har man inte ännu krävt att asfaltbranschen eller asfaltproducenterna skall redovisa för olika livscykelutredningar.
