Environmental issues and sustainable development are key factors where asphalt pavement technology can play an even more positive active role in the future. Asphalt is ideally suited for recycling and re-use of materials, meeting the challenges of limited material resources. It has potential to reduce global warming through low energy concepts for mix production and placing. Furthermore, it allows meeting specific environmental demands of denser populated agglomerations, such as reduction of traffic noise by introducing new innovative materials and designs as well as reductions of congestion from road works by improving durability and aging resistance. Hence, it is now time to establish a holistic way of approach and introduce this concept in life cycle analysis as well as research and development.
In order to form a coordinate platform for progress in this field and based on the achievements of the Symposium ISAP2008 August 18th to 20th in Zurich (http://www.empa.ch/isap2008) a new ISAP Technical Committee TC APE Asphalt Pavement and Environment has been formed.
The goals of this TC APE are
- Promote recycling of asphalt as sustainable material of high value by considering technical, environmental and economical aspects. Re-use as much as possible at quality levels as high as possible.
- Promote safe and beneficial re-use of second mat. in asphalt
- Find new solutions and new techniques to improve the environmental compatibility of asphalt pavement
- Find new solutions and new techniques for asphalt pavements to improve environment (e.g. multifunctionality)
- Find new solutions and new technique & understand mechanisms!!
- Link with other international groups, e.g. RILEM TC SIB, WG05 Recycling and WG06 on Cold Recycling and the recently established RILEM TC RAP – Asphalt Pavement Recycling.
