The purpose of this study was to evaluate chip seal performance with neat and polymer-modified asphalt cement. These chip seals were fabricated with various aggregate combinations to emphasize aggregate retention in cold climates with the accelerated chip seal simulation device. Three aggregate types at low temperatures were used to compare the aggregate retention performances of neat versus modified asphalt cement. A major finding of this research was that polymer modification of neat asphalt cement improved aggregate retention performance. In addition, results showed that a decrease in temperature causes increasing aggregate loss.
