Property	Value (Approx.)	Note
Material Composition	Crushed Limestone + Fines	Optimized for maximum compaction.
Loose Density	2,400 – 2,600 lbs/yd³	As it sits in the truck.
Compacted Density	2,800 – 3,000 lbs/yd³	After being rolled or tamped.
Tonnage Multiplier	1.5	This accounts for both the weight and the 15% extra volume needed due to compaction.
