Automatic Laboratory Soil Compactor — High-Precision Compaction for Professional Soil Testing

The Automatic Soil Compactor is built to perform uniform, repeatable soil compaction while eliminating human error. This automated system compacts and rotates the mold after each blow, ensuring even distribution of force across the entire surface of the soil specimen. The compactor also tracks the number of hammer blows and automatically shuts off once the preset number is reached.

This intelligent automation not only improves testing accuracy but also helps laboratories maintain consistent results across multiple samples. Whether performing standard Proctor tests or modified Proctor tests, the Automatic Soil Compactor offers complete control, reliability, and uniformity.

 How the Automatic Soil Compactor Enhances Testing Accuracy

The advanced design of the Automatic Soil Compactor ensures the hammer achieves the correct drop height every time. This is critical for meeting the requirements of both standard and modified compaction tests. The unit supports:

• A 5.5 lb hammer with a 12-inch drop height for standard Proctor testing

• A 10 lb hammer with an 18-inch drop height for modified Proctor testing

Additionally, the mold rotates in a smooth circular motion after each hammer blow, ensuring the soil is compacted uniformly. This method eliminates uneven compaction patterns that often occur in manual testing.

The result?
Precise, repeatable, laboratory-grade compaction data.

Automatic Soil Compactor — Engineered for Efficiency and Long-Term Durability

Every component of the Automatic Soil Compactor is designed with durability and performance in mind. Its heavy-duty construction allows long operation periods without overheating or mechanical wear. The automated system significantly reduces operator involvement, improving workflow efficiency and boosting laboratory throughput.

Key performance features include:

• Automatic hammer blow count tracking

• Preset blow number shutdown

• Rotating mold system for uniform compaction

• Precision hammer drop mechanism

• Compatibility with both 4-inch and 6-inch compaction molds

The compactor’s intelligent operational design ensures clean, consistent compaction for every test cycle.

 Automatic Soil Compactor — Compatibility with Compaction Molds

To ensure flexibility, the Automatic Soil Compactor is compatible with both 4-inch and 6-inch compaction molds. These molds—models 2814114 and 2814115—must be ordered separately. They are constructed to meet ASTM and AASHTO specifications and ensure accurate sample preparation for moisture-density relationships.

Using the correct compaction molds ensures that each soil sample is compacted to the required standard, helping engineers evaluate:

• Maximum dry density (MDD)

• Optimum moisture content (OMC)

• Soil strength and stability

• Suitability for construction applications

Applications of the Automatic Soil Compactor in Geotechnical Engineering

The Automatic Soil Compactor is widely used in:

• Commercial soil laboratories

• Highway and pavement engineering

• Geotechnical engineering firms

• Civil engineering departments

• Construction material testing facilities

Accurate compaction testing is essential for ensuring the quality and safety of infrastructure projects such as roads, railways, embankments, airfields, and building foundations.

Why the Automatic Soil Compactor Is a Powerful Investment for Your Laboratory

The Automatic Soil Compactor offers multiple benefits:

• Higher accuracy than manual compaction

• Faster test processing

• Reduced operator fatigue

• Greater repeatability and reliability

• Compliance with ASTM and AASHTO standards

• Uniform compaction due to automatic mold rotation

By integrating automation with precise mechanical engineering, this compactor delivers consistent, scientifically valid compaction data that enhances laboratory efficiency and project reliability.
