Empa - Concrete Asphalt - Highrap

Highly Recycled Asphalt Pavement (HighRAP) Stockpiles of Reclaimed Asphalt Pavement keep accumulating in Switzerland. The reasons for this include lack of long-term performance experience, as well as the unreliable nature of high RAP mixture design and quality control procedures. The HighRAP project will address these problems by building on ...

2011-3-1  The selected project consisted in rehabilitating the pavement of a section of highway A-140, located in Huesca, Spain. The section was 5.9 km long and the annual average daily traffic was 6980 with 8.5% of heavy vehicles.The top 80 mm of the asphalt mix was milled from the damaged pavement, and an 80 mm asphalt layer of S-20 recycled mixture containing 60% RAP (S20R60) was then laid.
