A compaction device was developed that permits aggregate samples to be compacted by using the dynamic test equipment. Use of the device eliminates the need to move the specimen after it has been prepared. Tests were conducted to establish compaction procedures and to determine whether specimens compacted with the device experienced moisture or fines migration. The tests demonstrated that the method can be used to compact dense-graded aggregate materials to the modified Proctor (AASHTO T 180) maximum density without creating segregation or moisture migration. However, fines and moisture migration were observed when dry material and material significantly wetter than optimum were used. Recommendations are presented for preparing samples for dynamic testing using the device developed. Also included is an engineering drawing of the compaction device.
