The goal of the study was to correlate the results of a laboratory test procedure measuring aggregate polish resistance with skid resistance in bituminous pavements. This correlation would be instrumental in identifying skid-resistant aggregates and would create the potential for assuring lifelong skid-resistant bituminous pavements. The study was conducted in two phases. The first estimated the empirical relationship between aggregate microtexture and cumulative polishing using a modification of ASTM D-3319 and ASTM E-303. An exponential model was developed which realistically approximantes the minimum polish value observed with the theoretical asymptote of the polishing rate curve. The magnitude of this asymptote, PV, correlated well with New Jersey's skid resistance experience with specific aggregate types and was subsequently used in the study's second phase. In the second portion of the study, a more detailed relationship between PV and long-term minimum skid resistance was sought. Experiments were conducted to evaluate polish values of aggregates and skid resistance of bituminous pavements composed of these aggregates, and to collect environmental data on selected skid test sites over a period of one year.
