Compaction of Materials
BTI compactors achieve material compaction by using impulse force and
vibration to displace air and water pockets in the material. Compaction
performance depends on 3 items:
• Type and size of material being compacted
• Moisture content of the material
• Depths of lifts being compacted
Use a short trial of the compactor to determine the optimum depth of lift
and speed of boom travel to achieve the required density. This value will
vary depending on the material's composition and size. For example,
marbles being a uniform shape do not pack as well as gravel, which has
uneven shapes allowing the stones to interlock with each other.
You can reach nearly 100% of the maximum material density with a BTI
compactor by using smaller lifts, and increasing the holding time in each
spot. Typical hourly production rates to compact soil to over 95% its
original density are;
TC51L/FC / TC51H/FC: 14-22 cu yds (11-17 cu M) per hour
TC71 / TC71FC: 18-27 cu yds (14-21 cu M) per hour
TC80: 23-32 cu yds (18-25 cu M) per hour
TC91S: 25-35 cu yds (19-27 cu M) per hour
TC151S / TC151SH: 65-75 cu yds (50-57 cu M) per hour
TC301 / TC301H: 110-130 cu yds (84-99 cu M) per hour
Always operate the carrier engine at the minimum speed required to
achieve the desired result. This allows the hydraulic system to run cooler.
Excess flow beyond recommended levels can damage the compactor
motor.
Ensure the compactor base plate is in contact with the soil before operat-
ing.
When using a BTI compactor it is the amplitude (up and down motion)
of the plate, which does the compaction and not the compactor weight or
the carrier boom down-force. As you apply down-force to the compactor,
the carrier will lift slightly giving you an indication that the compactor is
properly pressed onto the material. Too much boom down-force inhibits
the up and down motion, reducing the compactor's impact force.
(Improper operation of the compactor can result in premature failure of
the rubber isolators.)
