Rolling Techniques
A well laid mat can end up with a poor ride quality if
proper rolling methods are not followed. Consult your
compaction equipment manufacture's manuals and
handbooks on compaction techniques.
Controlling Mat Quality
The primary purpose of the asphalt paver is to place a
smooth mat of material. The primary function of System
Five is to control the vertical position of the screed in
relation to the surface being paved. Automatic grade and
slope control systems can help tremendously in controlling
mat smoothness but mat quality is also dependent on the
following factors:
• Non-stop, continuous operation of paver
• Constant speed of paver
• Truck exchange
• Head of material
