This roller automates vibration frequency depending on the
amplitude as set by the operator. BOMAG offers intelligent
compaction, which controls the compactive effort based on
density levels being “read” by the machine.  Without exception,
the crews in charge of asphalt pavers and compactors have to
hustle to get their jobs done and open the roads to traffic. In
response to public pressure to minimize time spent with lane
closures and traffic disruption, contractors recently have
increased the production rates of their asphalt paving trains.
To achieve specified densities, however, it is commonly accepted
that an asphalt mat needs 10 to 14 impacts per foot from the
vibratory compactor as it rolls along. So to move faster, the
roller's frequency, or vibrations per minute, must increase.
“Rollers used to work at 2400 vibrations per minute, and now you
have highway compactors that do 4000 vibrations per minute,”
said Chuck Deahl, national accounts manager for BOMAG Americas
Inc. “We must control impacts per fo
