Balancing Durability and Safe Function in Dense-Graded Asphalt Pavements

Thursday, January 11, 2018, 8:00 AM-12:00 PM, Convention Center
Danny Gierhart, Asphalt Institute, presiding
Sponsored by Standing Committee on Surface Requirements of Asphalt Mixtures; Standing Committee on Design and Rehabilitation of Asphalt Pavements; Standing Committee on Pavement Surface Properties and Vehicle Interaction; Standing Committee on Asphalt Pavement Construction and Rehabilitation; Standing Committee on Critical Issues and Emerging Technologies in Asphalt; and Standing Committee on Structural Requirements of Asphalt Mixtures

To improve the durability of their asphalt mixtures, transportation agencies have implemented volumetrically increased binders or performance-based balanced mix design and acceptance specifications. Even with training on best construction practices and such new technologies as intelligent compaction, these durability strategies could affect the safe function of a pavement. This workshop addresses ways to improve durability and maintain safety.
