The resonant crushing hammer head moves forward rapidly while exciting the road surface resonance, with the resultant impact force pointing downward. This creates a certain angle between the fractured cracks and the road surface. This angle allows the碎石 blocks to interlock, and after compaction, they fit together more tightly, thereby enhancing the gravel stabilizing layer's performance. In contrast, the impact force of the conventional heavy hammer crushing method is vertically downward, and the碎石 cracks can only be roughly perpendicular to the road surface, which is不利于 the bearing and stability of the stabilizing layer.
