TRC2201 - Update to ARDOT Superpave Gyratory Compaction (SGC) Specification to Increase Pavement Durability

项目名称：	TRC2201 - Update to ARDOT Superpave Gyratory Compaction (SGC) Specification to Increase Pavement Durability
摘要：	The overall objective of the proposed research is to increase the durability of asphalt pavements. This study proposes to evaluate current mix designs for surface asphalt concrete hot-mix (ACHM) used around the State of Arkansas when reducing the number of design gyrations (Ndes) and examine its effect(s) on change in mixture durability (rutting and cracking performance). In particular, the key is to assure that the mixtures produced with reduced Ndes will have sufficient asphalt binder content to provide enhanced long-term cracking performance in conjunction with maintaining adequate aggregate structure to resist the permanent deformation (rutting) in the field for a given traffic level. Increasing the durability of asphalt pavements will result in both a reduction in the extent of necessary maintenance, preservation, and rehabilitation efforts/costs, and in a longer pavement life which will significantly reduce life-cycle costs of pavements. Also, the proposed study is the next logical step in fully implementing a performance engineered mixture design (PEMD) system for Arkansas.
