Keeping the Asphalt in the Road - Experiences from Different Asphalt Recycling Technologies

This paper reviews modem technologies for the recycling of asphalt, which is a key element for effective use of resources. The major goal of the industry is to create a true recycling, meaning that the reclaimed asphalt is used in the same road layer where it has been used before. This requires the ability to produce high-quality asphalt while incorporating high-ratios of reclaimed asphalt. Depending on the situation of the regional road construction industry different strategies for re-using reclaimed asphalt are appropriate. In this paper, we provide an overview on best practices for recycling on asphalt mixing plants.
