Title: A STUDY ON COMPACTION CONTROL BY FWD IN RAILWAY EMBANKMENT WORK
Abstract: The intensity of compaction in railway embankment is controlled by K30-value in the plate loading test for road. However, the plate loading test takes much time and needs a large reaction equipment. Thus, it is necessary to work out a simple and easy method for compaction control in railway embankment work. The present paper gives an outline of the rolling compaction test to applying FWD to compaction control in railway embankment work. The result from rolling compaction test shows that K-value by FWD correlates with several values indicating the compaction level (degree of compaction, air void ratio, K30-value), leading to the conclusion that it is possible to apply FWD to compaction control in railway embankment work.
