Enter aggregate data.
Design Settings
Uses standard Marshall volumetric equations. Acceptance limits are shown as a MoRTH-style guide only — always verify against the exact specification and mix grade governing your project.
Marshall Specimen Data
Enter one row per bitumen content. Gmb = bulk specific gravity (enter directly, or fill Weight in Air / SSD / Water Weight and it will be calculated for you). Gmm = maximum theoretical specific gravity. Stability in kN; Flow in mm.
| Bitumen % | Gmb | Gmm | Stability (kN) | Flow (mm) | Weight in Air (g) | SSD Weight (g) | Water Weight (g) | VA % | VMA % | VFB % |
