A rammer compactor delivers high impact force which is great for those cohesive and semi-cohesive soils from clay to sandy soils that require that high impact. These pieces of equipment are powered by an engine powering a piston set with two sets of springs on a plate that is angled forward so that as the machine jumps it travels forwards.

Dec 21, 2020The pneumatic tired roller is ideal for compaction of cohesion-less or slightly cohesive soils. These soils include gravels, sands, clayey sands, silty sands and even sandy clays. The pressure applied by them is distributed over relatively larger areas, which prevents the soil from collapsing. Wobble Wheel Roller

All three examples of small compaction equipment listed below may be referred to by different names. Upright Rammers Also known as wacker packers or jumping jacks, upright rammers work great when compacting cohesive soils because of the size of the plate. The smaller plate size allows for a more focused and direct compaction.

Soil compaction is most likely to occur when soil moisture is at or near field capacity, that is, when soil pores or voids are filled with equal amounts of air and water. Under these conditions, aggregates can be "lubricated" by water and readily reposition themselves through the air spaces under heavy traffic and when farm equipment is used.

The right equipment. For best results, use a machine that applies a vibratory force to the soil, such as vibratory or oscillating rollers. These machines apply a rapid series of blows to the surface of the soil, which impacts the deep layers below the surface, resulting in better compaction.

So as machines get bigger, they get more efficient and effective, but also heavier, so they also can create more damage through soil compaction.". The rule of thumb is that whatever pressure is in the tire, the resulting pressure exerted on the ground is 10% to 20% more than that, Harris says. Excess ground-contact pressure from the tires is ...

The heavier the machine, the more effective the compaction. Understand the soil. Before you begin compacting, you must identify the soil group you are working with. Different soil types have different maximum densities and optimum moisture levels that can impact results and consistency. The three basic soil groups are: cohesive, granular, and ...

Randall Reeder, a retired Extension ag engineer from Ohio State University, has done research on soil compaction for more than 30 years. Reeder conservatively estimates that most farmers can expect a 5% to 10% yield loss from compaction. However, research has shown that the yield loss can be as great as 55%.

Soil handling - The movement, transport, handling and stockpiling of soil destroys aeration pore spaces and disrupts soil aggregates. Soil cuts, fills and leveling compacts the soil. Soil handling equipment can be large and heavy, allowing compaction many inches deep. Avoidance. Compaction can occur on any soil texture.

Soil particles stick together. High impact compaction is the best choice. Clay is a type of cohesive soil. Granular Soils. Soil particles are bigger in size than the clay particles. These soils offer good drainage. Shaking or vibratory compaction technique is the best choice. Sand or gravel is a type of granular soil. Granular and Cohesive Soils

An Ohio State study comparing compaction down to a depth of 20-inches caused by tracked and wheeled tractors found that the best result for minimizing soil compaction was achieved with duals running at low inflation pressure (Table 6). Another Ohio State study compared half-tracks and four different tire configurations on a combine.

Compaction of soils in the field can be done by a variety of compaction equipment. The following are the different actions or effects of various compaction equipment on soils: 1. Static compaction - smooth wheel rollers. 2. Kneading compaction - sheep's foot rollers. 3. Vibration compaction - vibratory rollers. 4. Tamping - tampers.

The rate of the needed compaction test degree is determined by the soil property and the water content in the soil. A successful soil compaction procedure subjects the soil to utmost maximum dry unit of the soil moisture content at an optimum moisture content level. For compressibility, water is added to dry soil to optimally act as a lubricant.

There are three basic types of compaction machines: rammers, vibratory plates, and rollers. Rammers. Rammers apply high-impact compaction forces generated by a small gasoline or diesel engine that powers a piston with two sets of springs. The machines are inclined slightly so as to travel forward with each bounce, guided by the operator.

Single-plate compactors with up to 5,000 pounds of force are ideal for smaller areas and work on both dirt and gravel. Reversible compactors have up to 9,000 pounds of force, making them better for deeper compaction. If you have clay soil, you might need a heavy-duty plate compactor since clay soil requires more force for compaction.
