To determine this combined portion, the flaky stone from a representative sample should first be separated out. Flakiness index is weight of flaky stone metal divided by weight of stone sample. Only the elongated particles are separated out from the remaining (non-flaky) stone metal. Elongation index is weight of elongated particles divided by total non flaky particles. The values of flakiness index and elongation index so found are added up. How to calculate Quantity and Loose volume of WMM Layer | Compaction of WMM for Road Construction
