Compaction Equipment
Rammers deliver a high impact force (high amplitude)
making them an excellent choice for cohesive and semi-cohesive soils. Frequency range is 500 to 750 blows per minute. Rammers get compaction force from a small gasoline or diesel engine powering a large piston set with two sets of springs. The rammer is inclined at a forward angle to allow forward travel as the machine jumps. Rammers cover three types of compaction: impact, vibration and kneading.
Forward Plate Compactors are low amplitude and high frequency,
designed to compact granular soils and asphalt. Gasoline or diesel engines drive one or two eccentric weights at a high speed to develop compaction force. The resulting vibrations cause forward motion. The engine
and handle are vibration-isolated from the vibrating
plate. The heavier the plate, the more compaction force it generates. Frequency range is usually 2500 vpm to 6000 vpm. Plates used for asphalt have a water tank and sprinkler system to prevent asphalt from sticking to the bottom of the baseplate. Vibration is the one principal compaction effect.
Reversible Plate Compactors have two eccentric weights that allow smooth transition for forward or reverse travel, plus increased compaction force as the result of dual weights. Due to their weight and force, reversible plates are ideal for semi-cohesive soils.
A reversible is possibly the best compaction buy dollar
for dollar. Unlike forward plates, the reversible's forward travel may be stopped and the machine will maintain its force for 'spot' compaction.
Rollers are available in several categories: walk-behind and ride-on, which are available as smooth drum, padded drum and rubber-tired models; and are further divided into static and vibratory sub-categories.

Forward Plate Compactors - Single Direction
Forward Plate Compactors are low amplitude and high frequency,
designed to compact granular soils and asphalt. Gasoline or diesel engines drive one or two eccentric weights at a high speed to develop compaction force. The resulting vibrations cause forward motion. The engine
and handle are vibration-isolated from the vibrating
plate. The heavier the plate, the more compaction force it generates. Frequency range is usually 2500 vpm to 6000 vpm. Plates used for asphalt have a water tank and sprinkler system to prevent asphalt from sticking to the bottom of the baseplate. Vibration is the one principal compaction effect.

Rollers
Rollers are available in several categories: walk-behind and ride-on, which are available as smooth drum, padded drum and rubber-tired models; and are further divided into static and vibratory sub-categories.
Walk Behind A popular design for many years, smooth-drum machines are ideal for both soil and asphalt. Dual steel drums are mounted on a rigid frame and powered by gasoline or diesel engines. Steering is done by manually turning the machine handle. Frequency is around 4000 vpm and amplitudes range from .018 to .020. Vibration is provided by eccentric shafts placed in the drums or mounted on the frame.
Ride On Configured as static steel-wheel rollers, ride-ons are used primarily for asphalt surface sealing and finishing work in the larger (8 to 15 ton) range. Small ride-on units are used for patch jobs with thin lifts.
The trend is toward vibratory rollers. Tandem vibratory rollers are usually found with drum widths of 30in up to 110in, with the most common being 48in.
The ideal solution for asphalt patching jobs too small to be handled with tandem rollers. Dependability and performance make these rollers a favorite of contractors, highway repair agencies and municipalities. A fully enclosed hydrostatic-drive system offers infinitely variable speed control, smooth acceleration and braking.
Double-drum rollers easily tackle large asphalt compaction jobs and feature built-in water tanks, hydrostatic drive and spray bars. The MRH800-Series tandem rollers feature a streamlined design that allows access to tighter areas. These versatile rollers are ideal for asphalt patching or compaction of granular soils.
Multiquip Tandem Drum Rollers
These models are lightweight for easy maneuvering, but engineered for heavy-duty work with hydraulic drive, articulated steering and tight clearance ability: 19" high curb clearance and 1.25" near walls and structures.

Soil compaction is defined as the method of mechanically increasing the density of soil. In construction soil compaction is a significant part of the building process. If preformed incorrectly it could result in unnecessary maintenance costs or structure failure. There are two different types of compaction force, static and vibratory. Static force is the weight of the machine its self. That weight is applied downward on the soil, compressing the soil particles. The only way to change the pressure of the compaction is to add or subtract weight to the machine. With the static force compaction is limited to the upper soil layers. Vibratory force of compaction uses a engine powered mechanism to create a downward pressure along with the machine static weight. In rammers that mechanism is usually a rotating eccentric weight or piston/spring combination. Unlike the static force, with this vibration that the mechanism creates it compacts the top layers of soil as well as deeper layers.
The different types of soil need to be taken into consideration when dealing with soil compaction. Every soil type has its own unique requirements. Soil types are classified by grain size. A soil's makeup determines the best compaction method to use. There are three basic soil groups, cohesive, granular, and organic. Cohesive soils have the smallest particles of all three soils; they are dense and tightly bound together by molecular attraction. Proper water content and the soil must be evenly distributed for proper compaction. Granular soil has fine to medium gravel, and are know for there water-draining properties. Granular soil can be seen with the naked eye, and is gritty when rubbed together. Also when it is dry it has no cohesive strength, and a soil sample will crumble easily.
Although soil type is key to determining the type of machine that should be used for the job, compaction specs and job site conditions must all so be considered. With cohesive soils a machine with high impact force is required, to give pressure to the soil and force out the air. A rammer would be the best choice for a compaction job with cohesive soil, and a pad-foot vibratory roller would be ideal if higher production is needed. Since granular soil particles require a vibratory action to move them. A forward vibratory plate would be ideal for these conditions. Again for higher production level a reversible plate or a smooth drum vibratory roller. Granular soil particles, depending on size respond to vibrations differently. Smaller particles require high vibrations. When larger particles are present a larger machine is required to obtain lower vibrations and higher compaction forces.
