Gradation for WMM

2. Grading

Grading Total sample weight (gm)

Grading limits per MoRTH Table 400-13 (Grading for Wet Mix Macadam). Verify against the current edition for your project.

3. Sieve analysis

Enter weight retained (gm) on each sieve. % passing and the pass/fail check are computed automatically.

Fines requirement: the fraction passing 75 µm should not exceed two-thirds of the fraction passing 600 µm — and IRC:109-2015 states tighter fines limits than the older MoRTH table; confirm the limit set required by your contract specification before certifying. The “Passing 0.075 ≤ ⅔ × passing 0.6” row is computed automatically once weights are entered on both the 0.6 mm and 0.075 mm sieves.
