Book excerpt: Real-time measurement of the tire-road friction coefficient is extremely valuable for road-maintenance operations and highway safety management. This paper presents a systematic framework to predict skid resistance of wet pavement with a non-contact method, which could be a potential approach for real-time measurements of pavement friction. The grip potential of pavement is estimated according to the measured pavement texture based on theoretical simulation of the complete hysteresis and partial adhesive effects during tire sliding on wet pavement. Such a method could be potentially used for the purpose of harmonization analysis of skid resistance and potential capability of optimization of pavement surface texture.

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.

Book Synopsis Skid Resistance and Road-Surface Texture by : H. Augustin
Download or read book Skid Resistance and Road-Surface Texture written by H. Augustin and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important factor resulting from the investigation of the effects of road-surface texture characteristics on skid resistance is the technological consequences with a view to the composition of the wearing course. In the course of this work, qualitative data were obtained and evaluated, which shall later be supplemented by quantitative data, about the coefficient of friction measured with the locked wheel on the one hand and through tracings of the surfaces of cores and laboratory samples on the other hand. The tracings were carried out with a device that has a measuring accuracy of ±5 ?m and a step length of 12.5 ?m. To investigate the time-dependent changes of the road-surface texture under traffic, tests were carried out with a polishing simulator. Through the tracing of selected profiles and the statistical evaluation of the results before and after polishing, comparisons can be made with other existing systems for the measurement of the surface texture as well as prescriptions for new technological demands on materials for the construction of wearing courses. As a result of these investigations, the polishing test according to the British Standard Polished Stone Value (PSV) has been made obligatory for Austria.
Book Synopsis Road Surface Micro and Macrotexture Influence on Skid Resistance by : Murat Ergün
Download or read book Road Surface Micro and Macrotexture Influence on Skid Resistance written by Murat Ergün and published by . This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The fast development of car technology has led to a steady increase ofthe speed of the vehicles. International studies show that increase causes increase in the accidents. The transport infrastructure such as pavement surface texture has not followed this development. In the wet weather, even at low speed, the skid resistance between the road surface and tyre can be quite low. International studies emphasise that there is a relation between the accident rate and the friction coefficient. The main goal of this study is to analyse the influence of road surface texture on skid resistance. The ultimate goal is to investigate the possibility of assessing pavement skid resistance by means of a new model which only uses surface texture parameters. In Chapter 1, the influence of skid resistance on the accident rates isexplained. Then, necessity of monitoring to road surface texture is highlighted. Thedefination of the surface texture is made in Chapter 2. The main surface texturedescriptors are surface texture (microtexture, macrotexture, and megatexture) and(un)evenness (longitudinal- and transverse evenness). The measuring methods ofsurface texture and (un)evenness are explained in Chapter 3. The description of skid resistance is explained from the historical development point of view in Chapter 4. In Chapter 5, the measuring methods of skid resistance are explained. Nowadays, different methods are in use to measure skid resistance.The main factors that affect skid resistance are pavement surface texture, the tyre, vehicle speed, and water film thickness as explained in Chapter 6. Recent researches on those factors are demonstrated. Then, the previously proposed models about skid resistance are explained in Chapter 7. In Chapter 8, the tests to study the influence of surface micro- and macrotexture on skid resistance are explained as mainly field and laboratory tests.The field tests are namely: skid resistance test by Odoliograph, the macrotexture by Mobile Laser Profilometer, and low-speed skid resistance spot tests by British Pendulum. Then, the cores are extracted from these spots. In the laboratory test, the new contactless microtexture measurement method is developed by using the Image Analysis Technique and applied on the extracted cores to measure microtexture of samples.The results of field and laboratory tests are presented in Chapter 9. The analysis of the results is made in Chapter 10.Finally, this study concluded that it is possible to predict the skid resistance of road surfaces by means of a new model which only uses surface texture parameters. Also, the road surface microtexture can be measurable with using the Image Analysis Technique. This study shows that it should be possible for systematic network monitoring of low friction spots on the road surface by using fast, non-contact texture measurement methods in the future.
