GRADING CATEGORY (Gc)
There is now a Grading Category (Gc) which specifies the percentage of material passing d/D, therefore a 10/20 would have a grading category Gc85/20 this means that up to 85% of the material can pass the 20mm sieve (D) and up to 20% can pass the 10mm sieve (d).
The grading for a 10/20 Gc85/20 would be

FLAKINESS (FI)The Flakiness test has changed you now use a bar sieve along with the new sieve sizes, the results are lower then the old method and for Asphalts a Flakiness of less then 35 is now acceptable FI35.
