This pavement macrotexture review is for highway engineers and administrators concerned with the improvement of pavement surface texture as a countermeasure for skidding accidents. A summary is presented of the fundamentals of tire-pavement skid resistance and the importance of pavement surface texture in reducing skidding accidents. This includes a discussion of the skid number and skid number-speed gradient and of the role of pavement surface microtexture and macrotexture in skid resistance. The most commonly used methods of measuring pavement macrotexture are described, and ways of achieving high macrotexture in new pavements and of restoring high macrotexture in existing pavements are given.

"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.

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.

Macrotexture, which influences vehicle-roadway skid resistance, refers to the texture of the pavement due to the arrangement of aggregate particles. Pavement surfaces are subjected to seasonal variations, and over time the embedded aggregates become polished due to the onslaught of traffic. Research has shown that wet-weather crashes are influenced by the macrotexture of the pavement surface. The TRB National Cooperative Highway Research Program's NCHRP Research Report 964: Protocols for Network-Level Macrotexture Measurement provides state transportation pavement engineers and other practitioners with recommended protocols for macrotexture test measures, equipment specifications, and data quality assurance practices.
