:hmhd:dh:hm:h Compaction of impact roller The characteristic is that an object of a certain mass is used to fall from a certain height to impact the compacted material, causing the material to produce a large stress change speed. What is different from ordinary vibration compaction is that impact compaction changes the high vibration frequency and low amplitude
vibration beating
mode of the vibratory roller into a low vibration frequency and high amplitude
High energy impact compaction method. The impact roller impacts the filled 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, as well as the earth-rock mixed roadbed under the structural layer, are sheared, broken and interacted with each other. Filling and compacting, with the propagation of shock waves, a
