Title: Combined Aggregate Gradation As A Method for Mitigating Studded Tire Wear On PCCP
Abstract: Two sections of pavement were built with different specifications for the gradation of the aggregates, one with the standard WSDOT specification and one with a combined gradation, to determine if the use of the combined gradation would result in a pavement more resistant to studded tire wear. The standard gradation can result in a gap-graded aggregate whereas the combined gradation produces a more uniform gradation. Wear rates calculated for the most recent data set collected in the fall of 2006 reveals no difference in wear rates between the pavements paved with the standard gradation versus those paved with the combined gradation.
