dc.description.abstractAs a road surface is traveled on, a polishing phenomenon occurs. Depending on the binder used, aggregate used, and period in the life cycle of the road this polishing can either improve or hurt friction performance of the surface. Being able to accurately predict change in friction as wear occurs changing the surface texture of a road is desirable. Due to this desire, the studies discussed in this thesis aim to correlate the surface changes associated with state of wear of a surface with the available friction provided by the surface to the tire. During experimentation two road samples (pills) prepared in the lab were polished and tested at 15-minute intervals for a total of two hours. After polishing, the pills were tested on the British Pendulum Tester and then scanned using a laser texture scanner. The scan data was then filtered and post processed to obtain the spectral data of the surface profile. The results of surface spectra and friction responses were then examined for correlations. Examination of different comparisons between polishing time, friction response, and road surface data was conducted to search for a relationship between wear and friction.en_US
