Ensure Proper Aggregate Shape for Stronger Pavements
The Flakiness & Elongation Index Test determines the percentage of flat and elongated particles in coarse aggregates.
Excess flaky and elongated particles can cause:
Weak interlocking
Reduced strength
Poor compaction
Lower pavement durability
This professional Excel Auto-Calculation Format simplifies the testing and reporting process.
What This Format Calculates
✔ Flakiness Index (%)
✔ Elongation Index (%)
✔ Combined FI + EI (%)
✔ Sieve-wise Observation Table
✔ Final Acceptance Check
Prepared strictly as per:
IS 2386 Part 1
MoRTH Specifications for Road & Bridge Works
Why This Test is Important?
In highway construction, aggregate shape significantly affects:
Load transfer capacity
Stability of DBM & BC layers
Concrete strength
Workability
Compaction efficiency
MoRTH generally limits Combined FI + EI to specified values for pavement layers.
Accurate calculation ensures compliance and prevents mix rejection.
