Abstract:

Providing cost-effective, safe and smooth pavement surface is a priority for transportation agencies. The major challenge, however, is to provide a sustainable surface skid resistance for economy and preservation of superior safety, yet smooth enough for quiet and comfortable ride. Some advancement in smoothness indices and texturing methods has occurred as part of this balancing act between the pavement smoothness and surface friction. However, the sustainability issue of different surface textures has not yet fully addressed. There is also a need to develop comprehensive models that predict the short-and long-term performances of different surface textures. This paper addresses the performance of concrete pavement surface textures using the Federal Highway Administration (FHWA) Long Term Pavement Performance Program (LTPP) data in GPS 3, 4 and 5. The analysis shows that tined/grooved textures maintain consistently higher skid resistance over time and concrete pavements surface friction is insensitive to ambient condition. Cumulative traffic passes was more sensitive to frictional performance than the cumulative axle loads. Two alternative models have also been successfully developed for prediction of concrete pavements long-term skid resistance as a function of texture type, cumulative traffic passes, speed, and concrete compressive strength. These models were shown to be statistically significant at 95% confidence levels with reasonable prediction accuracy.
