Abstract
This document provides information to facilitate better understanding of how to effectively use asphalt mixtures with varying levels of reclaimed asphalt pavement (RAP). It highlights key practices employed by several State Departments of Transportation (DOTs) to achieve engineering, economic and environmental benefits when using high RAP mixtures. Additionally, it presents a staged approach based on the identified key practices and strategies for reliably increasing RAP content.
