Characterizing Rider Safety in Terms of Asphalt Pavement Surface Texture

Measuring pavement friction directly involves specialized equipment with a relatively high initial cost. Many devices require that measurements be made on field pavement sections, incurring further delay in opening a new pavement to traffic. Several recent studies have correlated asphalt pavement surface texture with friction using relatively inexpensive, non-intrusive devices. These devices can be used in the laboratory as well as in the field and have shown promise in estimating not only pavement surface texture and friction, but also noise emissions and energy usage in terms of vehicle rolling resistance. With further development, these methods will give pavement designers the necessary tools to characterize asphalt pavement surface texture in terms of pavement friction, leading to safer roadways. This project refines and applies these methods to several plant produced mixtures to estimate surface texture and friction. This will allow for the assessment of rider safety in terms of surface texture and friction. Limits on the mix design parameters most affecting rider safety (friction) will be proposed and a straw-man specification may be drafted. It is expected that at least one peer-reviewed journal article and a final report will be produced.
