Comparison Experimental Study on Subgrade Compaction Quality Test Methods

Abstract:

The principles of the continuous test methods for compaction degree is introduced based on subgrade engineering cases. The compaction parameter CMV associated with subgrade compaction is obtained through spectrum analysis on the response of a vibratory drum during compaction operations. Comparative analysis is conducted on CMV and the in situ test index E_vd, which verifies that the continuous test index CMV has a high reliability and a good correlation with E_vd and can objectively and comprehensively reflect the subgrade compaction quality and provides necessary basis for the application of the continuous quality test methods for subgrade.
