|Rapid Impact Compaction... Another form of Dynamic Compaction?|
Rapid impact compaction (RIC) is a technique that was developed in the United Kingdom in the 1990’s for rapid densification of soils to repair bomb craters on runways. The primary usage in the U.K. is for shallow compaction of floor slab and roadway subgrades. RIC has recently been introduced in the United States and some engineers in the U.S. are mistakenly equating RIC and conventional dynamic compaction. While RIC performs well for the shallow applications for which it was intended, it is categorically not suited for deep compaction of soils. The purpose of this paper is to provide a technical comparison of the two techniques.
