Compaction machines use downward force and precision control to achieve the density you need for foundations or pavement. Our selection of road rollers includes a variety of drum sizes as well as vibratory controls that help you achieve your target asphalt density.

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.

4 Tips to Achieve Optimal Asphalt Compaction | World of Asphalt

Compaction in its most basic form is the act of getting the air out of your asphalt mix in order to reach peak performance of your mix. Compaction starts behind the screen – both tamping and vibratory. Operators only have a limited amount of time to get the best density from your asphalt mix. Smoothness of the road is directly impacted by the ...

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 ...
