Book excerpt: A study was conducted on the use of porous friction courses for airport pavements as a means of alleviating aircraft hydroplaning. The study consisted of a laboratory investigation of material requirements and mix design development and of a field study of construction control, construction processes, and long-term performance. The laboratory results were correlated where possible with the field observations. Satisfactory performance was obtained with a recommended aggregate gradation. A procedure for obtaining a design asphalt content and field mixing temperature, minimum field permeability values, and laboratory procedures for conducting permeability tests are described. A standard recommended guide specification is also included as an appendix.

Available in PDF, EPUB and Kindle. Book excerpt: Hydroplaning is the loss of traction between tire and pavement due to the presence of a layer of water. This loss of traction can result in loss of vehicle control. A porous friction surface (PFS) applied over an existing pavement permits the water to drain laterally and vertically away from the tire path, effectively lowering hydroplaning potential. Equipment used to measure pavement drainage (permeability) is discussed with respect to usage on porous friction surface. Background information on hydroplaning, flow theory, and PFS field performance as they are affected by permeability are also presented. Pavement permeability equipment is divided into two groups: static test devices and dynamic test devices. Static test devices measure pavement permeability up to the hydrodynamic pressure range. Dynamic test devices measure pavement permeability in the hydrodynamic pressure range. Two dynamic test devices and four static devices are considered for measuring PFS permeability. Permeability tests are recommended to measure PFS permeability for maintenance purposes and construction control. Dynamic devices cited in this report could possibly estimate hydroplaning potential; further research must be done to determine this. Permeability devices cannot be used to accurately estimate friction of a pavement surface, however, decreased permeability of a pavement infers a decrease in friction. A static test device, is recommended to measure PFS permeability.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the construction and early performance of a field trial of a Porous Friction Course (PFC) in Indiana. The PFC is compared to an adjacent section of Stone Matrix Asphalt (SMA) constructed at the same time using the same binder, coarse aggregate and fiber. Those mixes are also compared to a similar conventional Hot Mix Asphalt (HMA) surface constructed one to two months earlier. This evaluation shows that the PFC produces significantly lower noise levels than the HMA and SMA as measured by both the pass-by and close-proximity methods. The SMA produces higher noise levels than the HMA. The PFC also had the highest surface texture, as measured by the Circular Texture Meter; the HMA had the lowest texture. Data from the Circular Texture Meter and Dynamic Friction Tester were combined to determine the International Friction Index (FN60). The PFC provided the highest friction value, followed by the SMA. Both the PFC and SMA had substantially higher friction values than the HMA even though they were tested before opening the road to traffic. The friction values for the PFC and SMA are expected to increase after traffic wears away the binder film coating the protruding aggregate particles. The PFC also reduced splash and spray and improved visibility during rain events, as observed qualitatively. Long term performance of the PFC should be monitored to determine how long these benefits last, but initially the PFC appears to offer an efficient and economical way to reduce noise and maintain or even improve friction and visibility.

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.
