Book Synopsis Pavement Friction Test Tire Correlation. Final Report by : Rudolph Reuven Hegmon
Download or read book Pavement Friction Test Tire Correlation. Final Report written by Rudolph Reuven Hegmon and published by . This book was released on 1975 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: A correlation has been established between skid resistance measurements with the newly adopted test tire (ASTM E501) and the previous standard test tire (ASTM E249). The correlation is based on a large scale field test program, supported by laboratory tests on a high speed facility. Both tires respond in a similar way to changing test conditions, but tire E501 is expected to measure about 4 percent higher than tire E249 under standard test conditions at 40 mph. Prediction equations and the associated estimated variances are given for an all-inclusive correlation, as well as separate equations for three speeds (20, 40, and 60 mph) and separate equations for each of the four pavements used in this program. Limited tests on dry pavements also show generally higher readings with tire E501.

Available in PDF, EPUB and Kindle. Book excerpt: The physical interaction between roadway surface and vehicle tires has been widely investigated. Roadway conditions, traffic characteristics, environmental factors, and driver habits all play important roles in skid resistance and safety characteristics of pavements. It is difficult, however, to use quantitative statements to describe these uncertain factors, and the poor correlation between pavement performance and these factors makes it impossible to predict skid-resistance properties with regression analysis. To evaluate pavement skid resistance, a new methodology has been introduced which uses fuzzy-sets mathematics. The skid performance of pavement sections can be grouped by fuzzy cluster analysis of the data obtained from sand-patch and British pendulum number testing, as well as skid numbers measured on test sections with blank and ribbed test tires. A computer model which predicts locations that have a high accident potential can be established from the fuzzy cluster results. These results can also be used to predict seasonal variations in pavement skid resistance. The principle discussed here can be valuable in all types of pavement-condition evaluations. This paper presents the state of the art in using fuzzy cluster analysis for evaluating pavement skid resistance, first describing the objectives and the scope of possible applications of this methodology, and then giving the calculation procedures and the results of a case study using this technique. Recommendations for future pavement-skid-resistance research are outlined.

Book Synopsis Skid Resistance of Wet-Weather Accident Sites by : RR. Hegmon
Download or read book Skid Resistance of Wet-Weather Accident Sites written by RR. Hegmon and published by . This book was released on 1986 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A small-scale, wet-weather accident study was conducted in the years 1981 to 1983 as part of a wider study on pavement texture. The researchers were notified of wet-weather accident occurrences, and the skid resistance was measured as soon as possible after the accident, usually within one day, but never more than two days. During the study period, 79 such sites were tested, 21 of which had multiple accidents. All sites were tested with the ribbed and blank test tires. Similar tests were made on control sections within 1.6 km (1 mile) of the accident sites. These were selected to have geometric and traffic characteristics similar to those of the accident sites. As it turned out, the data base was too small to warrant definitive conclusions. Uncertainties about accident causation were reflected in the fact that the data from the control sites were not significantly different from those of the accident sites. The results, however, show a trend consistent with findings by other researchers. Skid resistance measured with the blank tire is not only lower than that measured with the ribbed tire, but is also better as a predictor of skidding accident potential. Wet-weather accident data from Florida were also analyzed, and the results reinforced this conclusion. The use of data from both the blank and the ribbed tire for pavement evaluation is recommended for future study.
Book Synopsis Evaluation of Pavement Friction Characteristics by : John Jewett Henry
Download or read book Evaluation of Pavement Friction Characteristics written by John Jewett Henry and published by Transportation Research Board. 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.

Book Synopsis Surface Texture Classification by : GR. Musgrove
Download or read book Surface Texture Classification written by GR. Musgrove and published by . This book was released on 1982 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of a driver to stop on a wet pavement surface has been shown as a relationship between a tire and the pavement surface texture. For a number of years, the Ontario Ministry of Transportation and Communications has been classifying pavement surface textures and correlating these textures with the skid number of the surface, as measured by a brake-force trailer. The skid trailer number can be explained now in terms of the pavement surface texture. This paper contains a summary of the test procedure, a discussion of the texture classification system, and the relationship of the six texture parameters is discussed in terms of the equation used to generate a skid number at 100 km/h (62 mph). The advantages of using this system as a complement to present skid testing procedures are outlined, with particular attention to its use in those areas which cannot be tested by the brake-force trailer and in the area of mix design studies. The paper concludes with a discussion of some potential uses for the test method in future research work in Ontario, including the semiautomation of the interpretation procedure.
