DBM Marshall Stability Test

1. Sample details

Description of mix Source Location Date of casting Date of testing Tested by

2. Test parameters

Grading Binder type Blows GSB (bulk sp. gravity of aggregate) GSE (effective sp. gravity of aggregate) Sp. Gravity of bitumen (Gb) Proving Ring Factor (kgs) (reference only) Design air voids used for min. VMA reference (%)

GSE (effective specific gravity of aggregate) is used in the Gmm formula; GSB (bulk specific gravity) is used in the VMA formula — the standard Asphalt Institute MS-2 treatment. If GSE has not been separately determined, enter the same value as GSB.

3. Marshall test results

One row per specimen. Weights in grams. Load in kN is the value read off the proving-ring/machine calibration for the dial gauge reading.

4. Additional requirements (single-point tests)

Coating of aggregate particle (%) Tensile Strength Ratio, TSR (%) Minimum VMA required (%) (auto-suggested from Table 500-12; edit if needed)

5. Summary & conformity (average of specimens)

Averages are taken across every specimen row with complete data, then checked against MoRTH Table 500-11 by binder type.

6. Report

This app saves everything (test data) for the active project in your browser, tied to this folder. Logos and project details are entered once on the main Projects page and shared by every module.
