Performance-Based Mix Design of Porous Friction Courses

  Project Data
Funds: $300,000
Research Agency: National Center for Asphalt Technology--Auburn University
Principal Investigator: Don Watson
Effective Date: 7/31/2014
Completion Date: 1/31/2017

OBJECTIVE

The objective of this research was to develop a performance-based mix design method for PFC mixtures. For purposes of this research, a PFC is defined as having a typical layer thickness of 0.75 to 1.25 inches and a design air void content above 15%. The mix design method shall be based on the use of the Superpave gyratory compactor and shall include (a) selection of materials, i.e., binder, aggregate, additives, etc.; (b) consideration of climate and traffic; and (c) laboratory performance tests and criteria for properties related to rutting, raveling, cracking, moisture susceptibility, permeability, noise reduction, and friction, to achieve a balance in the mix design between PFC durability and functionality.
