Compaction Equipment - Pavement Interactive
There are three basic pieces of equipment available for HMA compaction: (1) the paver screed, (2) the steel wheel roller and (3) the pneumatic tire roller. Each piece of equipment compacts the HMA by two principal means: By applying its weight to the HMA surface and compressing the material underneath the ground contact area. Since this compression will be greater for longer periods of contact, lower equipment speeds will produce more compression.

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 ...
