Asphalt Goes Green
Energy-saving warm-mix technology has saved more than $2.2 billion during the 2011 paving season. Approximately 60.2 million tons of reclaimed asphalt pavement (RAP) and 1.08 million ton of reclaimed asphalt shingles (RAS) are used in the United States (US) for use in new pavements and, about 19% of all asphalt produced in the country was made using warm-mix asphalt (WMA) technologies. Asphalt pavements are the sustainable option for paving roads and highways. The use of warm mix requires less energy to produce high-quality pavements and, at the same time, saves cost and preserves natural resources. But there is still room to do more, and the asphalt pavement industry in the US is working to reach higher levels of road sustainability. However, this is not the case in Europe which has been reluctant to use this technology. Some key trials using warm asphalt in Europe could result in wider use of the technology.
