Recycled Asphalt Pavements (RAP) Part 1: The What, Why, and How of RAP?
Asphalt pavement recycling has been conducted in some form since 1915. Today, recycled asphalt pavement (RAP) is utilized in the production of asphalt mixtures for applications ranging from driveways to airport runways. Asphalt pavement is one of the highest recycled products in the United States with over 82 million tons of RAP used in new asphalt mixtures in 2018. Utilization of RAP provides for favorable economic (lower mixture cost), environmental (less energy consumption and greenhouse gas emissions) and societal (extends available natural resources) impacts.
While the advantages of RAP use are immense, effective and responsible RAP use is critical and is driven by proper RAP processing and stockpile management to help ensure the final produced asphalt mixture has the performance characteristics to meet the intended service application and performance requirements.

In this webinar attendees will:
1. Learn about historical RAP use
2. Recognize the need for and advantages of RAP use
3. Understand the types of RAP products and how they differ
4. Learn the leading practices for processing and stockpile management
5. Understand RAP product variability compared to virgin aggregate and overall mix variability

This webinar is RECP approved.
