THE RESILIENT AND FATIGUE CHARACTERISTICS OF ASPHALT MIXTURES PROCESSED BY THE DRYER-DRUM MIXER

This report summarizes the findings of a study to evaluate the engineering properties of asphalt mixtures produced using a dryer-drum plant. Included is a comparison of the elastic and fatigue properties of dryer-drum mixtures with the properties of asphalt mixtures produced with conventional plants. The effects of curing treatment and mixing temperature were evaluated; however, it was not possible to study the possible effects of moisture since no moisture differences were obtained. All specimens were plant mixed and laboratory compacted. The engineering properties of the dryer-drum mixtures generally were equal to those of previously evaluated inservice and laboratory-prepared mixtures. Based on the findings of this study and the experience and findings of others, it is felt that satisfactory mixtures can be produced with dryer-drum plants. /Authors/
