SURFACE TEXTURE VERSUS SKIDDING: MEASUREMENTS, FRICTIONAL ASPECTS, AND SAFETY FEATURES OF TIRE-PAVEMENT INTERACTIONS. A SYMPOSIUM
Surface texture, with its attendant effects on phenomena at the tire-pavement interface, greatly influences the frictional properties and therefore the safety of highway and runway surfaces. Tire-pavement interface frictional forces must be sufficient to prevent skidding and loss of directional control under generally accepted normal operating conditions. Texture at the pavement surface not only contributes directly to development of frictional forces, but also provides sources of contact with the tire by projecting through lubricating films of water, oil, or other contaminants. Type and amount of texture are important variables in both cases. Texture plays an increasingly more important role as increasing vehicular speeds increase the lubricant film thicknesses encountered by the moving tire. Measurement and description of textural parameters have not been standardized with regard to procedures and terminology. Recognizing this fact, ASTM Committee E-17 on Skid Resistance organized and sponsored this symposium, emphasizing the following four areas of interest in the contribution of surface texture to tire-pavement interaction processes: (1) findings from recent research directed toward measuring and describing surface texture for purposes of predicting skid resistance from texture, (2) effects of the frictional aspects of surface texture on skid resistance, (3) procedures for characterizing standard surfaces, and (4) surface texture in relation to highway and runway safety. The initial four papers are primarily concerned with procedures for measuring and evaluating surface texture; the next four papers address the more fundamental aspects of tire-pavement interface phenomena; the concluding two papers are directed more toward the safety aspects of pavement surface texture.
