Compaction logs
that close the lift.
Record nuclear gauge readings, Proctor results, and compaction test data lift by lift, test by test. Pass/fail against spec. Inspector-ready report at the end of each day.
What it does
Test method logging
- Nuclear gauge (Troxler, Humboldt, CPN)
- Sand cone density tests
- Clegg hammer impact values
- Proctor reference (AASHTO T 99/T 180, ASTM D698/D1557)
Lift-by-lift records
- Log each lift with depth, location, and test number
- Pass/fail against target compaction % (e.g. 95% Standard Proctor)
- GPS coordinates and station/offset for each test
- Corrective action triggered automatically on failing lifts
Compliance documentation
- FAA, DOT, and UFC compaction documentation formats
- Photo attachments for witness records
- Inspector-ready compaction summary PDF
- Share via link — no login required
Production integration
- Compaction logs tied to production quantities
- Track compacted area and remaining work
- Daily compaction summary for the super and PM
- Feeds into as-built reports automatically
How it works
01
Set your compaction spec
Define the target compaction percentage, test method, and Proctor reference for the job. These apply to every lift logged.
02
Log tests in the field
After each test, enter the reading, depth, location, and pass/fail against spec. Takes under 30 seconds per test.
03
Flag failing lifts
Out-of-spec results flag immediately. Log corrective action (rework, re-compact, retest) and note what was done.
04
Export the compaction report
At job closeout or on inspector request, generate the compaction summary PDF showing all lifts, tests, and pass/fail status.
Who uses this
Road & earthwork crews
Document every compaction lift so the DOT inspector can sign off. No more missing test records on the day of inspection.
Quality control managers
Review compaction pass rates by zone, lift, or date. See trends and address issues before they become rework.
Project managers
Compaction documentation is complete before closeout, not assembled afterward from paper sheets.

Common questions
What compaction test methods does Gradelog support?
Gradelog supports nuclear gauge (Troxler, Humboldt, CPN), sand cone density tests, Clegg hammer impact value tests, and direct shear methods. You can set the Proctor reference (AASHTO T 99/T 180 or ASTM D698/D1557) per job.
Can I attach photos to compaction tests?
Yes. You can attach one or more photos to each compaction test record — useful for witness testing documentation, gauge-on-ground photos, or soil condition records required by some DOT specs.
Does Gradelog support DOT compaction documentation formats?
Yes. The compaction report exports in a format accepted by most state DOT specs. Enterprise customers can request custom report templates for specific state or agency requirements.
How do failing compaction tests trigger corrective actions?
When a test result falls below the specified minimum, Gradelog automatically creates a corrective action record. The super or PM is notified, and the corrective action stays open until a passing retest is logged.
