The ideal vibratory frequency and amplitude settings are a compromise based on desired mat smoothness, HMA characteristics and lift thickness. d. Poor performance on sandy gravels o Not suitable for compact sand. Vibratory steel wheel rollers offer potential compaction advantages over static steel wheel rollers but they also require the operator to control more compaction variables (amplitude, frequency and vibratory mode use) and there are certain situations under which they must be used with caution (e.g., over shallow underground utilities, in residential areas, thin overlays).
