The Superpave Gyratory Compaction gyrates specimen molds at a rate of 30.0 gyrations per minute throughout compaction. Then the compactor tilts the specimen molds at an internal angle of 1.16 ± 0.02° (~1.25°) and the ram applies and maintains a pressure of 600 ± 18 kPa (~600 kPa) perpendicular to the cylindrical axis of the specimen during compaction.
Answer: Option B
