This book was released on 1992 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2000 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book Design of Open graded Asphalt Friction Courses written by R. W. Smith and published by . This book was released on 1974 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to improve pavement skid resistance have shown the advantages of using open-graded asphalt paving mixtures. The concept used is that the open-graded asphalt friction course consists predominantly of a narrowly-graded coarse aggregate fraction with a sufficiently high interstitial void capacity to provide for a relatively high asphalt content, a high air void content, and a relatively small fraction of fine mixture while the fine aggregate fraction acts as a filler and imparts a "chocking action" to stabilize the coarse aggregate. The high asphalt content provides for mixture durability and the high air void content provides for adequate subsurface water drainage. The described method is relatively new, but has been used successfully on several FHWA, R & D Demonstration Projects.
Download or read book Laboratory Evaluation on the Performance Comparison Between OGFC Asphalt Reinforcement with Fibers and Modified with Nanosilica written by Javad Tanzadeh and published by . This book was released on 2020 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open-graded friction course (OGFC) is a mixture with gap-graded aggregate that is used in pavement surfacing. This research proposes methods to improve the durability and structural contribution of OGFC mixtures through laboratory performance testing. A draindown test, a Cantabro test, a permeability test, and an indirect tensile strength test were used to evaluate the performance of OGFC mixtures. The main parameters of this research specify optimum bitumen and desirable air voids, maximum reduction of draindown and abrasion loss, and retained tensile strength ratio. It was observed that the effect of fiber in both states on bitumen percentage caused increased sensitivity to oxidation of the asphalt mixture; however, the effect of nanosilica on the reduction of sensitivity to oxidation was considerable. The effect of glass fiber in enhancing tensile strength was far higher than that of basalt fiber. In both states, nanosilica caused improved tensile strength of the mixture. Additionally, the moisture sensitivity of the OGFC mixtures with glass fiber was far better than that of the basalt fiber, and addition of nanosilica caused further improvement. The results showed a negative effect of the addition of basalt fiber alone in the asphalt mixture with a higher between percentage, necessitating the addition of nanosilica in conjunction with basalt fiber.
