Abstract:
Lack of understanding of the compaction mechanism, both in the laboratory and field, could result in significant under/overestimation of the RCCP performance. The literature (1987-2022) depicts that there are numerous techniques to design the RCCP in the laboratory; however, which method could closely simulate the field compaction is not fully explored. The present paper critically reviews the fundamental parameters affecting the strength characteristics of RCCP when compacted with different compaction mechanisms in the laboratory and attempts to rank the compaction methods based on the field performance. Also, recommendations have been made on how to fabricate the specimens without having much impact on the considered compaction technique. The techniques that have been considered are the vibratory hammer, vibratory table, modified Proctor, gyratory compactor, and special compactors such as the California kneading compactor, Marshall hammer, and duplex rollers. Based on the present review, future research prospects are outlined to improve the performance of RCCP.
