br Working principle of impact roller
brThe compaction feature of impact roller is to use an object of a certain mass to fall from a certain height and be compacted by the impact The material produces a large stress change speed. The difference from ordinary vibratory compaction is that impact compaction changes the high-frequency and low-amplitude vibration-beating compaction mode of the vibratory roller into a low-frequency, high-amplitude, high-energy vibration compaction. Impact
Compaction method. The impact roller impacts the filling body with its huge impact force, and is supplemented by rolling, kneading and other comprehensive effects. The original asphalt concrete structural layer of the old road and the earth-rock mixed roadbed under the structural layer are sheared and broken and filled closely with each other. , as the shock wave propagates, a
