In recent years, warm technologies have made enormous changes to the flexible pavement industry in a variety of ways. Warm-mix asphalt is the most recognizable warm technology product, although other advantages are associated with better compaction over a wide range of temperatures and have made long-haul distances appealing for some applications. This paper focuses on using warm-mix technology at traditional hot-mix production temperatures for the purpose of facilitating long haul distances. The primary objective of this study was to investigate how binder-related properties change with haul time when material was mixed at hot-mix temperatures. A secondary objective was to determine if any behavioral differences were present between asphalt binders with no additive, foamed asphalt binders, and asphalt binders with a chemical additive. Plant-mixed asphalt was used for the investigation. The overall conclusion of the research was that haul times of 1 to 8 h produced no major differences in aging for a given binder type or between binder types. Subtle differences were observed between binder types in some instances (e.g., low-temperature properties were slightly better for mixes using warm-mix technologies).
