Assessment of Real-Time Compaction Quality Test Indexes for Rockfill Material Based on Roller Vibratory Acceleration Analysis

Table 1

Compaction parameters of the test material.

Testing material	Standard rolling parameters			Requirements of compaction quality indexes
	Rolling times	Layer thickness (cm)	Driving speed (km/h)	Relative density	Dry density (g/cm^3)	Porosity
Main rockfill	Static roll (2), vibratory roll (8)	100	2.7 ± 0.2	—	≥2.22	≤21%
Secondary rockfill	Static roll (2), vibratory roll (8)	50	2.7 ± 0.2	≥0.90	≥2.33	≤20%
Filter material	Static roll (2), vibratory roll (8)	30	2.7 ± 0.2	≥0.85	≥2.08	—
