Mix Volumetrics — Dust-to-Binder Ratio
Dust-to-Binder Ratio calculation for asphalt mix design and QC.
The minus-75-micron dust doesn't act like aggregate — it dissolves into the binder and stiffens it into mastic. Too much and the glue turns brittle; too little and the mat stays tender under rollers. Baghouse fines returned inconsistently are the classic cause of a drifting ratio.
Formula
Note: Paving estimates only — the project mix design, agency specification and the plant's QC data govern. Temperature models are simplified; verify with an infrared gun and density gauge on the mat.

About Mix Volumetrics — Dust-to-Binder Ratio
Mix Volumetrics — Dust-to-Binder Ratio computes the governing relationship D/B = P₂₀₀ / Pbe live as you type. The minus-75-micron dust doesn't act like aggregate — it dissolves into the binder and stiffens it into mastic. Too much and the glue turns brittle; too little and the mat stays tender under rollers. Baghouse fines returned inconsistently are the classic cause of a drifting ratio. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Mix Volumetrics — Dust-to-Binder Ratio
- 1Enter your values — Passing 75 µm (P200), Effective binder Pbe (sensible defaults are pre-filled).
