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.

Available in PDF, EPUB and Kindle. Book excerpt: Highway noise is one of the most pressing of the surface characteristics issues facing the concrete paving industry. This is particularly true in urban areas, where not only is there a higher population density near major thoroughfares, but also a greater volume of commuter traffic. In 2004 and 2005, the Federal Highway Administration, Iowa State University, and the American Concrete Pavement Association initiated a five-year, multi-million dollar Portland Cement Concrete Surface Characteristics Program. This program is administered through the National Concrete Pavement Technology Center located at Iowa State University. The purpose of the program is to determine the interrelationship among noise, friction, smoothness, and texture properties of concrete pavements. This report addresses work conducted under Part 2 of the program. In Part 2, data were collected on 1,012 test sections totaling 240,000 ft., representing 395 unique pavement textures. This is the most comprehensive inventory of concrete pavement surface textures ever compiled. The inventory includes transverse and longitudinal tining, diamond grinding, various drag textures, grooving, exposed aggregate, shot peening, cold milling, and some asphalt pavements and surface treatments. A preliminary analysis of the data has revealed a number of important findings. For example, relationships between texture and noise are beginning to emerge. These are not based on nominal texture dimensions, however, since a second finding is that nominal dimensions are rarely observed to be found in place. Friction and noise are also found to have no relationship, demonstrating that quieter concrete pavements can be achieved without compromising this important characteristic.

This book was released on 1976 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents evaluation of one type of asphalt pavement that has shown it can provide superior skid resistance when wet. When first developed, this surface was called "Plant Mix Seal Coat" because of its resemblance to chip seals in common use; through development and usage it has been renamed "Open Graded Asphalt Friction Course."

Book excerpt: Safety is an important aspect of highway design. Texture and frictional properties are important characteristics in providing safe roadways. Longevity of desirable frictional properties is highly dependent on the aggregate within asphalt pavement. Iowa unfortunately has areas of the State where the locally available aggregate will not give long lasting desirable frictional properties. Iowa has utilized sprinkle treatments to improve the safety of many new asphalt concrete pavements.

Download or read book Identification of Laboratory Technique to Optimize Superpave HMA Surface Friction Characteristics written by Karol J. Kowalski and published by . This book was released on 2010-10-15 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wet pavement friction is known to be one of the most important roadway safety parameters. In this research, frictional properties of flexible (asphalt) pavements were investigated. As a part of this study, a laboratory device to polish asphalt specimens was refined and a procedure to evaluate mixture frictional properties was proposed. Following this procedure, 46 different Superpave mixtures, one stone matrix asphalt (SMA) mixture and one porous friction course (PFC) mixture were tested. In addition, 23 different asphalt and two concrete field sections were also tested for friction and noise. The results of both field and laboratory measurements were used to develop an International Friction Index (IFI)-based protocol for measurement of the frictional characteristics of asphalt pavements for laboratory friction measurements. Based on the results of the study, it appears the content of high friction aggregate should be 20% or more of the total aggregate blend when used with other, polish susceptible coarse aggregates; the frictional properties increased substantially as the friction aggregate content increased above 20%. Both steel slag and quartzite were found to improve the frictional properties of the blend, though steel slag had a lower polishing rate. In general, mixes containing soft limestone demonstrated lower friction values than comparable mixes with hard limestone or dolomite. Larger nominal maximum aggregate size mixes had better overall frictional performance than smaller sized mixes. In addition, mixes with higher fineness moduli generally had higher macrotexture and friction.

Download or read book Development of a Friction Performance Test for Compacted Asphalt Mixtures written by Rebecca S. McDaniel and published by . This book was released on 2018-03 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In a previous JTRP project published in 2010, Identification of Laboratory Techniques to Optimize Superpave HMA Surface Friction Characteristics, a laboratory procedure to polish and test the frictional properties of asphalt mixtures was developed. Subsequently, the procedure has been used in other research efforts to evaluate the frictional properties of recycled asphalt pavement (RAP) and local (possibly marginal) aggregate blends and for other testing purposes. Most notably, the procedure has been developed into Indiana Test Method (ITM) 221, "Acceptance Procedures for HMA Surface Mixture Coarse Aggregates for ESAL ¿10,000,000." The method requires compaction, polishing and testing of 500 mm by 500 mm (20 in. by 20 in.) square slabs of asphalt mix. This research project was initiated based to explore the possibility of expanding use of the lab polishing/testing procedure to test gyratory specimens or field cores. It was envisioned that such a method could be used during mix design as a check on potential frictional properties and/or as a quality acceptance test. A means of fabricating a circular test ring from seven cylindrical specimens was developed and used to test five different plant produced mixtures. Comparisons of ITM 221 slabs, gyratory specimens compacted to different air void contents and field cores showed cylindrical specimens could yield similar results to the accepted slab test method.

This book was released on 2000 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement design, construction, management, and research engineers, highway safety officials, and others concerned with pavement friction characteristics. It describes the current state of the practice and discusses the methods used for evaluating wet pavement friction characteristics of new and restored pavements. This synthesis reviews models used for measuring and evaluating friction and texture, causes for friction changes over time, and aggregate and mix design to provide adequate friction. Also presented are construction and surface restoration practices for providing good pavement surface characteristics. In addition, considerations of noise and ride quality are discussed when compromise may be required.
