Logistics & Transport Recommendations

Pallet Packaging Rule

Safe stacking limit: 17 pieces per pallet to stay within the 2,500 lbs standard wood pallet rating.

NMFC Item Guidance

Reference code: 40000 (Crushed Stone in Bulk). Rated under Class 50 based on 105 PCF density.

  • Shipment utilizes 1.6% of a standard 53ft trailer's 45,000 lbs legal cargo payload (44,300 lbs capacity remaining).
  • Standard GMA pallet recommendation: Maximum 17 units per pallet to remain within the 2,500 lbs safe working limit.

Shipping, Packaging & Stacking Specifications for Crushed Gravel

Transport & Palletizing Rules

Shipped in dump trailers or tandem axle tri-axles. Bulk density changes significantly when saturated with rainwater.

Typical Industrial Applications
  • Road base & driveways
  • French drains & septic drainfields
  • Asphalt & concrete aggregate
Critical Handling Cautions:
  • Wet gravel can weigh 15-20% more than dry gravel, risking axle weight ticket violations
Material density and metallurgical weight benchmarks correspond to standard test specifications from ASTM International and density rating tables from NMFTA.
