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

This study proposes to evaluate changing the current mix design strategies for surface asphalt concrete hot-mix (ACHM) used around the state of Arkansas by moving away from volumetric based mix design strategies to first establishing cracking and rutting properties (balanced mix design) followed by reporting the volumetrics. This combination of releasing a gyration requirement with performance testing is anticipated to create longer lasting, more durable flexible pavements. Increasing the durability of asphalt pavements will result in both a reduction in the extent of necessary maintenance, preservation, and rehabilitation costs, and will also result in a longer pavement life, which will also significantly reduce the life-cycle costs of pavements.
