Pebbles, Gravel, Crushed Stone, Macadam & Stone Chips

Pebbles, gravel, broken or crushed stone for specific uses — along with macadam of slag or dross, tarred macadam, and decorative or monument stone chips — are bulk construction and infrastructure materials whose trade value is often constrained by high freight costs relative to unit price, making domestic sourcing the norm and imports commercially significant mainly in coastal or border markets. Tarred macadam and slag-based macadam are distinguished from plain crushed stone by their binder content, which can affect classification. Monument and building stone chips are a separate commercial stream used in landscaping and memorial products.
