Evaluation of VDOT Chip Seal Practices: Materials and Design

Project No: 118820

Target Completion Date: August 31, 2023 Pavements

About the project:

There have been considerable research efforts conducted, in recent years, at local and national levels to investigate the effect of material characteristics as well as design techniques on the performance of chip seals. In addition, with the advancement of technology, new materials and additives have been introduced into the construction market with the goal of enhancing the performance of chip seals. Despite these advances, and the long history of chip seal use on its roadway network, the Virginia Department of Transportation (VDOT) has not undertaken a thorough review of its chip seal practices in more than 25 years. The objective of this research study will be to evaluate VDOT’s single layer (single layer and modified single layer) chip seal practices from a materials characterization and design perspective.
