Gauge to verdict
Enter the readings in the order the gauge gives them. RollPass shows dry density, water content, relative compaction, and a giant PASS or FAIL.
RollPass: Compaction PASS
Nuclear density gauge compaction app for soil techs who need a clean PASS or FAIL at the lift. Key wet density and moisture, pick the Proctor curve, and export signed PDF, CSV, or My Proof ZIP reports.
RollPass DC works offline on Android. It does not read or control the gauge, and it is not official acceptance. Verify every reading, curve, standardization, and project floor before accepting a lift.
Curve discipline
Store project Proctor curves, standard counts, gauge profile, areas, lifts, test pins, and re-test lineage on the device.
Signed reports
Preview the report before sharing. Export PDF, CSV, or My Proof ZIP files through Android share actions.
