Skid resistance and accident data were collected on 517 rural sections that represented random sample of Texas highways; skid resistance values were obtained through use of towed trailer employing locked-wheel principle on artificially wetted pavements; composite skid resistances of 0.4 and 0.3 for testing velocities of 20 and 50 mph, respectively, were selected as guidelines for considering surface improvements; skid resistance values of 0.31 and 0.24 at 20 and 50 mph, respectively, were recommended as minimum values.
