Abstract
This directed project examined the idea that increasing the amount of recycled asphalt product in road construction will result in a comparable performance to the current levels of recycled asphalt product in today’s pavement. A critical review of literature is structured in four areas: describing the need (financial and environmental) for the increased use of recycled materials, describing how others have addressed the issue and technology needed for increasing the use of recycled content, describing how some contractors have created the technology needed, and finally describing the direction needed in order to encourage customers and government agencies to embrace the idea of using asphalt created from a high percentage of recycled materials. Data collection involved actual projects using asphalt with an increased recycled content, comparing the performance and costs to a conventional asphalt mix.
