Proctor Compaction Test Lab — MDD & OMC
Your road project is on hold until compaction data is confirmed. Therefore, every day without your MDD and OMC values costs you schedule. Jancy Labs provides NABL accredited Proctor compaction testing — both Light and Heavy variants — as per IS 2720 Part 8, from our Madurai laboratory. Our reports carry NABL stamp TC-12176, accepted directly by NHAI, PWD, and PMGSY field offices.

WHAT IS THE PROCTOR COMPACTION TEST?
This test tells you the Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) your soil achieves under controlled compaction energy — consequently, these are the critical values for designing road subgrades, embankments, and backfills. Without these values, your field compaction has no verified target — therefore, every compacted layer becomes a compliance risk. Moreover, compaction without MDD/OMC data is the leading reason for pavement failures and project rejection during departmental inspections.
APPLICABLE STANDARDS
IS 2720 Part 8 specifies the exact compaction energy, mould dimensions, number of layers, and blows per layer for both standard and modified Proctor tests. Furthermore, it defines the precise rammer weight and drop height — so results stay consistent across all accredited labs. Jancy Labs therefore conducts this test strictly as per IS 2720 Part 8, with calibrated equipment, verified procedures, and no shortcuts.
WHY THIS TEST MATTERS FOR YOUR PROJECT
- NHAI & PWD approval requires it: Highway and road projects under NHAI, PWD, and PMGSY mandate MDD/OMC data before field compaction begins — no certified value, no layer clearance.
- Subgrade failure prevention: Compacting soil without knowing OMC produces weak subgrades; consequently, premature pavement failure becomes nearly unavoidable.
- PMGSY rural road compliance: PMGSY quality manuals require Proctor test results as part of the material approval register for every new road section.
- Embankment settlement control: Fill compacted at wrong moisture content settles unevenly; therefore, MDD/OMC data is essential for embankment design.
- DPR and tender documentation: Moreover, design project reports for highway tenders require certified soil compaction data from NABL accredited laboratories.
- Site engineer accountability: Field QC teams use MDD values to set compaction acceptance criteria — without lab-certified data, field engineers have no baseline.
Skipping the Proctor compaction test means your compaction targets are guesswork, and furthermore, departmental site inspections will flag non-compliance immediately.

How to Get Your Proctor Compaction Test Done
Getting your test done at Jancy Labs is straightforward. Simply follow these three steps:
1st step — Send Your Sample Pack your soil sample in a sealed polythene bag inside a rigid container to preserve moisture.
2nd step — We Test It On receipt, our team logs your sample and begins preparation as per IS 2720 Part 8.
3rd step — Get Your Certified Report Your report is couriered within 3–5 working days. The report is accepted directly by NHAI, PWD, PMGSY, and CPWD field offices.
Our Proctor Compaction Test Process — as per IS 2720 Part 8
Sample Preparation
- First, we receive and log your sample — assigning a sample ID and verifying quantity and labelling.
- Next, we air-dry the soil and pulverise clods to pass the required IS sieve size.
- We then prepare five or more specimens at incrementally increasing moisture contents.
- Consequently, each specimen undergoes compaction in the IS 2720 Part 8 mould — three layers, 56 blows per layer, using the 4.89 kg rammer at 450 mm drop.
Plotting the Compaction Curve
- We record the mass of compacted soil in the mould for each specimen.
- Subsequently, we extract sub-samples from each compacted specimen and determine water content in the oven.
- We then calculate dry density for each moisture content point and plot the compaction curve.
- Finally, we identify Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) from the peak of the curve.
A qualified Materials Engineer reviews every Proctor Compaction Test result and signs the report before we dispatch it.
Frequently Asked Questions — Proctor Compaction Test
1. How long does a Proctor Compaction Test take at Jancy Labs?
At Jancy Labs, the Proctor Compaction Test is typically completed within 3 to 5 working days from the date of sample receipt. However, turnaround may vary depending on current lab workload. Contact us directly at +91-8680049004 for time-critical project requirements.
2. Can I send my soil sample by courier to Jancy Labs?
Yes — Jancy Labs accepts soil samples dispatched by courier, goods transport, or personal drop-in at our Madurai facility. However, make sure you seal the sample in double polythene bags inside a rigid container — this prevents moisture loss in transit. Additionally, label the package clearly with project name, site location, sample ID, and test type required.
3. Is your Proctor Compaction Test report accepted by NHAI and PWD?
Yes, it is. Jancy Labs holds NABL accreditation TC-12176 under ISO 17025:2017, and our Proctor Compaction Test reports are routinely accepted by NHAI, PWD/TNPWD, PMGSY, and CPWD for road, rural, and building project approvals across Tamil Nadu.
4. Do you conduct both Light Compaction and Heavy Compaction testing?
Yes — Jancy Labs conducts Light Compaction (Standard Proctor) as per IS 2720 Part 7 and Heavy Compaction (Modified Proctor) as per IS 2720 Part 8. Therefore, please specify which variant you need on your sample label or submission form. Moreover, a qualified Materials Engineer oversees both test procedures and signs every report before dispatch.
5. How much soil sample do I need for a Proctor Compaction Test?
As per IS 2720 Part 8, the Heavy Compaction test requires approximately 25 kg of disturbed soil — enough to prepare five or more compaction specimens at varying moisture levels. Similarly, Light Compaction needs a comparable quantity. Therefore, send air-dried, representative samples from the proposed compaction zone to ensure accurate MDD and OMC results.
