B. Possible Application Problems
1. Not achieving specified
A. Frequency too high or too low - Use vibration meter or follow guide line
B. Too few passes.
C. Too many passes - density can be achieved and lost with too many passes.
D. Laboratory density is not correct.
2. Loose, rough surface
A. Too high a frequency on last pass - use 1200 vibrations
after last pass.
per minute or no vibration to tighten surface.
