3.5 Application
This plate is designed for compacting patchwork on asphalt, cohesive soils, granular soils,
sticky soils (clay or slit), gravel, sand, or mixed soils. It is designed to compacts cohesive and
granualr soils up to 28 inches, while its self-cleaning, open base plate minimizes rock and
dirt build up.
3.6 Operation
3.6.1 Run engine at full throttle and allow plate to pull itself along at its normal speed. When
operating on an incline it may be necessary to assist plate by pushing it forward slightly.
Depending on the material being compacted, three or four passes are recommended to
achieve the best compaction.
While a certain amount of moisture in the soil is necessary, excessive moisture may cause
soil particles to stick together and prevent good compaction. If soil is extremely wet, allow it
to dry somewhat before compacting.
3.6.2 If soil is so dry as to create dust clouds while operating plate, some moisture should be
added to the ground material to improve compaction. This will also reduce service to the air
filter.
When using the plate on paving stones, attach a pad to the bottom of the plate to prevent
chipping or grinding surface of the stones. A special polyurethane pad designed for this
purpose is available as an optional accessory.
4. MAINTENANCE
4.1 Cleaning the Plate
Clean the plate aer use to remove dirt, stones, and mud caught under the engine console.
If plate is being used in a dusty area, check engine cylinder cooling fins for heavy dirt
accumulation. Keep engine cylinder fins clean to prevent engine from overheating.
CAUTION
DO NOT operate plate on concrete or on extremely hard, dry, compacted
surfaces. The plate will jump rather than vibrate and could damage both
plate and engine.
4.2 Periodic Maintenance
The chart below lists basic engine maintenance. Refer to engine manufacturer's Operation
Manual for additional information on engine maintenance.

9. MORE COMPACTION TIPS
9.1 Soil Drop Test: Soil preparedness refers to the “wetness” of the dirt or soil. Soil
needs to be 50% dry and 50% wet, before starting compaction. A simple “hand test” can
determine this. Pick up a handful of soil with your hand and squeeze the dirt. Observe
whether the soil is powdery or if it breaks apart when dropped. If the soil does break apart,
it means that it is too dry. If the soil keeps together in one piece when dropped, it is ready
for compaction.
9.2 Soil Testing: Testing: The function of this step is to measure the density of an aggregate
material to ensure the increase of density when driving out air. At a low moisture content
level, there are more soil particles assembling together. In order to determine if the soil is
compacted properly, there are several methods.
9.2.1 Soil Testing: Test strips are useful to determine the method of compaction and
understand how many passes of your plate compactor are needed to achieve the optimum
compaction. Every layer of compacted soil meets a specific percentage on the proctor
curve. Through soil testing, it is possible to identify optimum moisture. Soil testing mea-
sures the soil density compared to the degree of compaction specifications, as well as the
eect of the moisture.
A common laboratory method called the Proctor Compaction Test can be used to deter-
mine the optimal moisture content for a given soil type. The goal of this method is to
understand the soil’s maximum dry density. A second method of soil testing is known as
the California Test 216 and is used to find the relative compaction of untreated and treated
soils.
Four factors account for optimum compaction including li thickness, pressure, and soil
moisture content. During the compaction process, the soil's moisture adds density and
lubricates soil particles, until there is a maximum dry unit weight without voids in the soil.
The table below explains the dierent outcomes and properties of fill materials.
21
9.3 Compaction Terms
9.3.1 Cohesive soils: Clays and mixes have a particular particle size of less than .003” or
.002” and are typically classified as cohesive soils. This type of soil is primarily used for
retaining pond beds and mound fills. These soils are dense due to the strongly bound mo-
lecular attraction. Cohesive soils and water will not mix easily, but only once the soils are
moist it will feel sticky.
9.3.2 Granular soils: These soils have particle sizes of .003” or greater, like sand. Water
drains easily through the soils particles of granular soils. The larger the particles, the larger
the equipment needed to achieve lower frequencies and higher compaction force. Plate
compactors are typically the best option for compacting granular soils - however, depend-
ing on the vibration frequency and particle size, reversible plate compactors and double
drum rollers may be more appropriate for this type of work.
9.3.3 Mixed soils: Sometimes soils can be a mixture of both types, cohesive and granular.
Thus choosing the appropriate compaction equipment is more diicult. We recommend
testing your equipment to match the best machine to the desired job.

9.4.4 Static Force: Found in the deadweight of machines, static force applies pressure
downward on soil surfaces. As a result, soil particles compress in the topsoil layer.
9.4.5 Vibratory Force: This force is engine-driven, creating a downward force, in addition
to the machine's static weight. Vibrations compress the soil material closer together to
increase density.
9.4.6 Types of Compaction: There are four types of compaction that can be applied to soils
or asphalt. Each one takes place using one of the two types of the forces explained above
(static or vibratory).
A. Vibration: Periodic motion of particles with rotating weight in opposite directions
from a position of equilibrium.
B. Impact: An action of one object coming into contact with another.
C. Kneading: Force is applied by alternating movement in adjacent positions.
D. Pressure: The process of continuous physical force against solid materials.
