Requirements for layered filling thickness and maximum particle size of FSW and detection methods of compaction degree.

Subgrade position	Compacted thickness (mm)	Maximum particle size (mm)	Detection methods of compaction degree
Upper roadbed	150	≤50	Sand replacement method
Lower roadbed	≤300	≤100	Settlement difference method
Upper embankment	≤300	≤300
Lower embankment	≤400	≤300
