Slag #53 INDOT

INDOT #53 slag is a dense graded aggregate that blends 1 1/2 inch slag stone with slag fines, creating a highly compactable and durable base material. Manufactured to meet Indiana Department of Transportation specifications, this steel slag aggregate delivers exceptional load-bearing strength and long-term stability. The combination of coarse stone and fines allows it to lock tightly under compaction, forming a firm surface that resists rutting and settlement.

Because of its strength and durability, INDOT #53 slag is widely used in structural base applications where consistent, spec-grade performance is required.

Common applications for INDOT #53 slag

• Road base and highway construction
