“…a high water drainage capacity) can improve the skid resistance over a wide range of speeds. Pioneering studies on the role of micro/macrotexture under wet braking conditions can be found (Giles, 1957(Giles, , 1965Schulze, 1959Schulze, , 1969Schulze, , 1970Moore, 1969Moore, , 1975Geyer, 1972;Holla and Yandell, 1973;Moore and Humphreys, 1973;Balmer, 1975;Rhode, 1976;Holla, 1977;Taneerananon and Yandell, 1981;Holt and Musgrove, 1982;Horne and Bü hlmann, 1983). Size, density and shape (slope) of the microasperities on top of the aggregates are essential to overcome the thin water film and to make direct contact with the rubber.…”

a b s t r a c tThere is a wide range of routine skid resistance measurement devices on the market. All of them are measuring the friction force between a rubber wheel and the wetted road surface.Common to all of them is that they are relatively complex and costly because generally a truck carrying a large water tank is needed to wet the surface with a defined water layer.Because of the limited amount of water they can carry they are limited in range. Besides that the measurement is depending on factors like water film thickness, temperature, measurement speed, rubber aging, rubber wear and even road evenness and curviness. All of these factors will affect the skid resistance and are difficult to control. We present a concept of contactless skid resistance measurement which is based on optical texture measurement and consists of two components: measurement of the pavement texture by means of an optical measuring system and calculation of the skid resistance based on the measured texture by means of a rubber friction model. The basic assumptions underlying the theoretical approach and the model itself based on the theory of Persson are presented. The concept is applied to a laboratory device called Wehner/Schulze (W/S) machine to prove the theoretical approach. The results are very promising. A strong indication could be provided that skid resistance could be measured without contact in the future. © 2015 Periodical Offices of Chang'an University.

“…The second possible source of difference was the presence of the film of oil drippings, worn rubber, and dust on the highway during testing. Previous research (10,25) has noted this film as a factor contributing to the so-called seasonal effect, since it is more pronounced during the summer months. It has also been noted that a dense surface is more sensitive to the seasonal effect than an open-textured one.…”

“…A análise dos dados dos trabalhos de Carpenter (1956), Giles (1957), Krummer e Meyer (1968), Mortimer et al (1970) (1987) interpretaram como a demanda de aderência de um veículo que possui 100% de eficiência de frenagem tanto para o caso de pista molhada quanto para seca. A demanda de aderência de um veículo de passeio trafegando em vias públicas com eficiência de frenagem menor do que 100% pode ser obtida a partir da apresentada por Mortimer et al (1970) (Fig.…”
