This synthesis will be of interest to construction, maintenance, pavement design, and materials engineers, pavement contractors, and others interested in the use of open-graded friction courses (OGFC) as an asphalt concrete pavement wearing surface. Information is provided on performance benefits and limitations of OGFC, material and mixture properties, and current construction practices in use in the United States and Europe. Advances in mixture design and construction techniques have overcome several of the performance limitations identified in early applications of OGFC, as well as enhanced the performance benefits associated with OGFC use. This report of the Transportation Research Board describes the current state of the practice with respect to the use of OGFC. Experience with the design, construction, and performance of OGFC is summarized, based on a review of the literature, documentation of experience from applications in the U.S. and Europe, and site visits to several states.

This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.

The issues concerning the IDT testing on the friction course were also identified and dealt with. In case of Georgia PEM, the primary objective was to compare its fracture performance with FC-5 limestone and granite. The Georgia PEM mixes were prepared using the same mix design as used by Georgia DOT. Both unaged and aged mixes were evaluated for their fracture performance using IDT testing and the results were compared with FC-5 and Novachip.

There are several issues of concern regarding indirect tension testing systems to evaluate and characterize tensile properties of open graded friction course (OGFC) mixture.It is necessary to evaluate the Superpave Indirect Tension Test (IDT) in terms of its ability to accurately determine tensile properties of OGFC mixture with an independent testing system.For this purpose, Superpave IDT and Dog-Bone Direct Tension Test (DBDT) were performed in resilient and creep loading modes to determine tensile properties of dense graded and OGFC mixture.It is also necessary to further verify with asphalt mixture, previously established correction factors based on three-dimensional finite element analysis to determine mixture properties accurately from the DBDT testing system.Prior verification was based only on polymer specimen of known properties.The tensile properties of dense graded and OGFC mixtures were successfully obtained with both testing systems employed in this study.Both Superpave IDT and DBDT provided reasonable and consistent test results with respect to test temperature, aging, and binder modification.Observed differences in creep response between the two were explained by well known phenomena involving effects of stress state on mixture properties (lower creep rate were obtained in Superpave IDT where the mixture is subjected to greater confinement) Thus, continued use of the Superpave IDT is recommended because it provides reasonable properties and is much more practical than DBDT.However, relationships to account for stress state effects need to be considered for mechanisms involving uniaxial stress states.DBDT creep compliance is more appropriate for uniaxial stress states (surface tension away from tires), while Superpave IDT creep compliance is more appropriate for stress states involving confinement (bottom or near-surface tension between tires).

Roads and Airports Pavement Surface Characteristics contains the papers presented at the 9th International Symposium on Pavement Surface Characteristics (SURF 2022, Milan, Italy, 12-14 September 2022). The symposium was jointly organized by the Italian company that manages Italy’s National Roads (ANAS –Ferrovie dello Stato Italiane Group), the World Road Association (PIARC) and Politecnico di Milano. The contributions aim to improve the quality of pavement surface characteristics while accomplishing efficiency, safety, sustainability, and addressing new generation mobility needs. The book covers topics from emerging research to engineering practice, and is divided in the following sections: Advanced and performing construction methods and equipment Next generation mobility Data monitoring and performance assessment Surface features and performances| Maintenance and preservation treatments Pavement management Economic and political strategies Safety and risk issues Minimizing road impacts Sustainability and performances issues about materials and design Pavements surfaces and urban heat islands Weather conditions impact Airport pavements Roads and Airports Pavement Surface Characteristics is of interest to academics, engineers and professionals in the fields of pavement engineering, transport infrastructure, and related disciplines.
