Proctor Compaction Test Lab — MDD & OMC
NABL Accredited Laboratory (Certificate No. TC-12176) as per ISO/IEC 17025:2017
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.

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.
Light vs Heavy Compaction — Which Do You Need?
IS 2720 defines two compaction energies. Your project specification determines which applies:
| Parameter | Light Compaction (Standard Proctor) | Heavy Compaction (Modified Proctor) |
|---|---|---|
| IS Standard | IS 2720 Part 7 | IS 2720 Part 8 |
| Rammer Weight | 2.6 kg | 4.89 kg |
| Drop Height | 310 mm | 450 mm |
| Number of Layers | 3 layers | 5 layers |
| Blows per Layer | 25 blows | 25 blows |
| Typical Application | General fill, low-traffic embankments | Highway subgrades, heavy-traffic pavements |
Most NHAI and PWD highway projects specify Heavy Compaction (Modified Proctor) per IS 2720 Part 8. If your specification does not state a variant, call us before dispatch and our Materials Engineer will advise.
Applicable Standards
IS 2720 Part 8 — Heavy Compaction
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.
Conducted With No Shortcuts
Jancy Labs therefore conducts this test strictly as per IS 2720 Part 8, with calibrated equipment, verified procedures, and no shortcuts. Our scope is verifiable on the NABL India portal → under Certificate TC-12176.
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. View all soil testing services →
Why Choose Jancy Labs for Proctor Compaction Testing
Your MDD and OMC values set the acceptance criteria for every compacted layer on site — therefore the lab producing them must be beyond question.
- Calibrated compaction moulds and standard rammers for both variants — 2.6 kg / 310 mm for Light and 4.89 kg / 450 mm for Heavy, with valid calibration certificates available on request.
- Both Light Compaction (IS 2720 Part 7) and Heavy Compaction (IS 2720 Part 8) conducted in-house — consequently, you get the exact variant your specification demands without outsourcing.
- Five or more specimens compacted at incrementally increasing moisture contents — therefore your compaction curve is properly defined, not interpolated from too few points.
- Every Proctor report reviewed and signed by a qualified Materials Engineer — moreover, results are cross-checked against project acceptance criteria before dispatch.
- NABL accredited laboratory — Certificate TC-12176 | ISO 17025:2017 — so our technical competence is independently verified, not self-declared.
- Reports routinely accepted by NHAI, PWD/TNPWD, PMGSY, and CPWD for road, rural, and building project approvals across Tamil Nadu.
Jancy Labs is built on one principle: every result must hold up at a DPR review, site inspection, or client audit. See our NABL accreditation → · Talk to our team today →
How to Get Your Proctor Compaction Test Done
Getting your test done at Jancy Labs is straightforward. Simply follow these three steps:
Send Your Sample
Pack your soil sample in a sealed polythene bag inside a rigid container to preserve moisture. Label clearly with project name, site location, sample ID, and test type required.
We Test It
On receipt, our team logs your sample and begins preparation as per IS 2720 Part 8 — air-drying, pulverising, sieving, and preparing five or more specimens.
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.
