Description

Heavy Compaction Test Set

The Heavy-Duty Compaction Test Apparatus from azalab is engineered for determining the maximum dry density and optimum moisture content (OMC) of soils using the Modified Proctor Method, as per IS 2720 (Part VIII).

This method is essential in geotechnical testing, roadwork, foundation design, and earthworks. The heavy compaction test simulates real-life compactive effort experienced in the field, ensuring reliable soil behavior prediction under load.aza

This version includes a 150 mm diameter mould with 2250 cc volume, making it suitable for coarse and granular soils.

What’s Included

Steel Compaction Mould – 150 mm I.D. × 127.3 mm height (volume 2250 cc)
Detachable Collar – Fits snugly on the mould
Base Plate – Threaded or clamp-lock type
Heavy Rammer – 4.89 kg with 450 mm drop, manually operated

Note: Mould available in both steel and gunmetal variants (as per request).

Applications

Heavy Proctor compaction tests
Construction compaction quality control
Subgrade and embankment testing
Foundation soil preparation
Soil stabilization research

FREQUENTLY ASKED QUESTIONS (FAQ)

Q1: Why use a 150 mm mould instead of 100 mm?
Larger moulds (150 mm) are used for coarse-grained soils with bigger particles, ensuring better accuracy.

Q2: What is the difference between steel and gunmetal moulds?
Gunmetal moulds offer higher corrosion resistance and durability but are heavier and costlier than steel.

Q3: Is this apparatus suitable for field use?
Yes, it is field-compatible, though typically used in mobile or lab setups due to its weight.

Q4: Can the rammer be used with different mould sizes?
This 4.89 kg rammer is calibrated for the 150 mm mould. For 100 mm moulds, a different compaction energy setup is required.

Q5: Is this test same as Modified Proctor?
Yes. In IS terms, it’s called the Heavy Compaction Test and is equivalent to the Modified Proctor Test (ASTM D1557).
