Skid Resistance Guidelines for Surface Improvements on Texas Highways
The report pertains to the selection of a minimum skid resistance coefficient for use as another guideline for surface improvements of Texas highways. The selection of the skid coefficient was approached from an accident standpoint, since experience on several sections of roadway indicated a sharp reduction of accidents after surface improvements. Skid resistance and accident data were collected on 517 rural sections that represented a random sample of Texas highways. The skid resistance values were obtained through the use of a towed trailer employing the locked wheel principle on artificially wetted pavements. An analysis of these data showed that the possibility of a roadway section having a high accident rate increased as the coefficient of friction decreased. On the basis of this study, skid resistance values of 0.4 and 0.3 for testing speeds of 20 and 50 miles per hour, respectively, were selected as guidelines for considering surface improvements. In addition, skid resistance values of 0.31 and 0.24 at 20 and 50 miles per hour, respectively, were recommended as minimum values. (Author)
