Book Description
In 2003, the Indiana Department of Transportation and the Federal Highway Administration allowed a test section of Porous Friction Course (PFC) to be placed on I-74 east of Indianapolis. The design, construction and early performance of that surface were compared to an adjacent SMA surface and a conventional Superpave HMA surface in a report prepared for the Institute for Safe, Quiet and Durable Highways. The early performance indicated that the PFC offered several advantages over the SMA and the conventional surfaces, including reduced tire/pavement noise, high friction and surface texture, and reduced splash and spray. There was a concern, however, that porous surfaces can lose their porosity, and therefore their performance advantages, over time. Consequently, the project summarized in this report was planned to continue monitoring the performance of the PFC and the comparison surfaces in order to investigate the durability of the porous surface over a five-year period (after construction). After five years under traffic, there have indeed been some changes in these properties. Most of the changes, however, took place quickly as the asphalt binder film coating the exposed aggregate particles was worn off by traffic. Since then, the changes have been relatively minor. The PFC section is still significantly quieter than the adjacent SMA section to which it has been compared. The PFC has retained most of its texture and is still providing good friction levels. Both the PFC and the SMA are still in very good condition with little distress and have higher friction levels than a section of dense graded asphalt constructed with similar materials that has also been evaluated for the duration of the study.

Book Description
"This report will be of interest to state DOT pavement engineers, environmental specialists, and noise analysts. The relationship between pavement surface texture and highway traffic noise is discussed. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search of both domestic and foreign publications."--Avant-propos.

Book Description
Performance-Based Mix Design for Porous Friction Courses presents a proposed mix design method for porous asphalt friction course (PFCs). PFCs have been used in the United States for many years. Their open aggregate gradations and resultant high air void contents provide PFCs with the ability to quickly remove water from the surface of a roadway, thus reducing the potential for vehicles to hydroplane and improving skid resistance. Splash, spray, and glare are also reduced, improving pavement marking visibility in wet weather. PFCs can also provide additional environmental benefits by reducing the pollutant load of storm water runoff as well as traffic noise. Despite their many benefits, the use of PFCs has been limited in part because of cost, lack of a standard mixture design method, premature failure by raveling or stripping, and loss of functionality by clogging with debris. In addition to the need to develop improved maintenance methods to address clogging, the performance of PFC mixtures will benefit from the development of a standardized mixture design method that balances durability in terms of resistance to premature failure with functionality in terms of permeability and noise reduction. The goal of this project was to achieve the required balance in the mix design between PFC durability and functionality.
