Techniques and Tools for Improving Density

This is the second of four Technical Briefs on Enhancing Durability of Asphalt Pavements Through Increased In-Place Density associated with the Federal Highway Administration (FHWA) Accelerated Implementation and Deployment of Pavement Technologies (AID-PT) program. The AID-PT program advances practices and technologies for constructing and maintaining high-quality, long-lasting pavements in accordance with six goals established by Congress. The overall objective of the demonstration project was to show that additional density could be obtained through improved techniques. This set of Tech Briefs focuses on the importance of mat and joint density, techniques and tools that have been demonstrated to help improve density, examples of specifications, and overcoming obstacles to achieving density. The information used to develop them was obtained through the literature, a series of workshops and support of 29 field demonstration projects performed by State Departments of Transportation (DOTs). This is the second in a series of four planned Technical Briefs meant to complement each other that are organized as follows: (1) Density Demonstration Projects and Related Specifications; (2) Techniques and Tools for Improving Density; (3) Overcoming Obstacles to Achieving Density; and (4) Improving Longitudinal Joint Performance.
