Effect of HMA properties on pavement surface characteristics

This paper discusses an extensive investigation conducted to evaluate the texture and skid resistance properties of seven wearing surfaces used at the Virginia Smart Road. Variation in skid resistance and surface macrotexture measurements due to HMA design characteristics and testing conditions (tire, test vehicle speed, and grade) were analyzed. The mixtures studied include five different SuperPave(tm) mixes, a stone mastic asphalt, and an open-graded friction course. The evaluation of the surface skid characteristics was based on measurements conducted using a locked-wheel trailer utilizing ASTM-specified ribbed and smooth tires. The macrotexture measurements were conducted using mainly a laser profiler. Statistical results indicated that, for the mixes studied, the roadway slope had insignificant effect on skid number measurements. Friction measurements, however, are dependent on the tire used, surface texture, age in service, and surface temperature.
