Overview & Cost Implications
Crushed stone gravel is essential for laying solid bases. Since angular gravel aggregates lock together under compaction, bulk material ordering includes a compaction factor of 10-15%.
Standard Formula Used
For estimating materials quantity and weight on job sites, estimators use this mathematical model:
Weight = Volume × Bulk Density INTEGRATED ESTIMATOR
