Abstract
Approximately 95 million metric tons of asphalt is recycled each year in the US; making it one of the most recycled materials. The technology for use of close to 100% recycled asphalt (RAP) is available. This study examines how owners of projects view the idea of using 100% RAP. The objectives of this study were to obtain city, town, county, and state government officials’ opinions on the use of 100% RAP and to find out how respondents felt about the use of RAP in their current asphalt roads. A survey was sent to 250 industry officials from all over the country. Statistical tests were conducted to see if the results were indicative of the population. Results show that there is some hesitation in the use of 100% recycled asphalt due to the unknown properties of the asphalt, past performance issues dealing with asphalt containing less than 100% RAP, and the unknown life expectancy of the 100% recycled asphalt. Also it was determined that 100% recycled asphalt would have to be less expensive than current asphalt on the market for it to be attractive.
