This study focused on the association of the dry process crumb rubber (CR) modification and Warm Mix Asphalt (WMA) methods. The effects of conditioning time, mixing and compaction temperatures were analyzed to overcome the binder-CR interaction problems at lower temperatures. Three different asphalt mixes were prepared: Hot Mix Asphalt (HMA), Dry process CR modified HMA (Dry HMA) and Dry Process CR modified WMA (Dry WMA). Since the conditioning time was significant to facilitate the bond between the CR particles and binder, CR modified mixes were conditioned for four different periods, (0, 45, 90 and 120 min.) to analyze the effects on the mixture properties and to come up with the optimum duration. In addition, to investigate the effect of mixing and compaction temperatures on the compactability and stability, Dry WMA mixes were prepared at three different temperature configurations.
