Aggregate Crushing Value Calculator

Calculate ACV from original mass and fines produced per BS 812-110. Classifies aggregate strength for pavement design.

Last updated 28 July 2026

About this tool

Calculate Aggregate Crushing Value from original specimen mass and mass of fines after applying 400 kN over 10 minutes per BS 812-110. Classified from strong (≤16%) to weak (>30%).

How to use this tool

Enter original mass and mass passing 2.36mm after test

Technical information

ACV (%) = (fines mass / original mass) × 100

Limitations

BS 812-110 has been superseded by BS EN 1097-2. ACV remains widely used in UK practice.
