摘要：

Recent improvements in warm mix asphalt technologies have spurred an aggressive adoption of these new practices within the asphalt paving industry. Concerns have arisen among federal and state agencies about the effects of this line of products on the performance of asphalt pavements. An investigation of the effects of lowering mixing, aging and compaction temperatures using Meadwestvaco's Evotherm 3G (TM) 09 chemical additive while varying the loose mix aging time was performed. Hamburg Wheel-Track Testing, Flow Number, Dynamic Modulus and Fracture Energy testing were used to evaluate mechanistic properties of the materials. It was found that lowering production temperatures has a significant influence on rutting related testing and a limited to negligible effect on dynamic modulus and low temperature fracture energy testing.
