The asphalt paving industry has always advocated recycling, including reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), tires, etc. In addition to conserving energy and protecting the environment, the use of RAP/RAS can significantly reduce the cost of hot-mix asphalt (HMA) paving. With the recent increased use of asphalt shingles in asphalt mixtures, there is a need to further study this issue. The main objective of this workshop is to present best practices for RAS collection, processing, screening, and stockpile management of processed shingles and RAS mix design, production, construction, and performance evaluation. This handbook is organized in four chapters. Chapter 1 provides an introduction, and Chapter 2 presents the best practices for the RAS processing and stockpile management in Texas. Chapter 3 discusses the balanced mix design for RAS/RAP/rejuvenators, and the production and field construction of RAS mixes. Finally, this report concludes with a summary described in Chapter 4.
