Segregation of asphalt mixtures has become a serious problem on coarse base mixes when they are improperly handled. One method to minimize segregation is to increase the fine aggregate portion. However, this may potentially adversely affect rutting resistance of the asphalt mixture. The objective of the study was to evaluate the effect of mix gradations on the rutting resistance of asphalt mixes. Six gradations from three aggregate sources were used in the study. Rutting was measured in the laboratory using the loaded wheel tester. Both standard and modified mixes were tested. Results from this study indicated that some modified mixes can improve rutting resistance and that aggregate sources can significantly affect the rutting potential of asphalt mixtures.
