Book excerpt: "It is generally agreed that the skid resistance of a pavement is controlled by the surface texture characteristics. Therefore, by measuring the relevant parameters describing texture, or by measuring a physical process dependent on texture, regression techniques can be used to relate skid resistance to the chosen texture parameter or process. Two scales of texture are of particular importance: microtexture (small-scale asperities) and macrotexture (large-scale asperities). This report describes work performed to: (1) review candidate macrotexture and microtexture measurement methods that can be made at highway speeds (at or above 40 mph), which are presently used or have potential for use in pavement texture measurement; (2) design and build a prototype of the most promising method; (3) evaluate the effects of pavement surface texture on skid resistance; and (4) investigate non-friction-related effects of pavement surface texture. A prototype noncontact vision system which takes texture measurements at highway speeds was developed, and several improvements were made to upgrade the system to provide an advanced-operational prototype. Both hardware and software enhancements have yielded a texture measurement system that is a fast, efficient, and reliable way of obtaining pavement macrotexture data"--Technical report documentation p.

Book excerpt: "This paper discusses the influence of roadway surface textures on the skid resistance, the speed-gradient, the wet-pavement accident rate, pavement wear, and the generation of tire-road interaction noise. The tendency of a vehicle to hydroplane is reduced by increasing the texture magnitude. Appropriate textures are developed by using open-graded asphalt friction surface courses and by grooving portland cement concrete with steel tines or a vibrating float while the concrete is plastic. Hardened pavements can be textured by grooving with a diamond saw or by resurfacing with an overlay. More development is needed in texture measurement techniques, especially in automating the stereo-photo interpretation method and the linear polarized laser technique"--Technical report documentation page

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.

Available in PDF, EPUB and Kindle. Book excerpt: It is well established among researchers in the pavement friction area that type of surface texture greatly influences the friction properties of pavement surfaces. Although it is recognized that other factors not necessarily related to surface texture also affect surface friction, various agencies in this country and abroad are engaged in developing methods for measuring pavement surface texture. Some 20-odd extant methods are currently used. The relative attributes of many of these methods are questioned, since results of tests using these methods have not, on the whole, produced consistent or reproducible quantitative results.
