Soil and Asphalt Compaction Equipment

Vibratory compaction relies on sending high frequency centrifugal force blows radiating downward through the asphalt-aggregate mix. When those forces hit a stable base structure, they “bounce” back and shake the material from the bottom up. This is the key concept in the vibratory principle - compaction actually starts at the bottom and
