[0072]Take the construction of a highway project in Jiangxi Province as an example. The compaction operation of AC-25 (gradation A) under a certain road surface mainly adopts two kinds of compaction machines, Hummer HD130 vibratory roller and Sany SPR300 tire roller. The HD130 road roller is a vibratory roller with double drums. During the operation, the front wheel mainly vibrates. The amplitude is 0.75mm, the vibration frequency is 42HZ, and the driving speed is roughly controlled at about 5km / h. The construction process of the compaction operation is a double-steel-wheel vibratory roller for static pressure once, followed by a double-steel-wheel vibratory roller for front wheel vibration compaction 2 to 4 times, and then two rubber-tired rollers for 1-2 times , the final double-drum roller static pressure until the road surface is flat and free of wheel marks.
[0073] Through data processing, each 0.4 second is a detection unit, and an effective acceleration value A is ob...
