EAF Steel Slag Aggregate for Road Base, Asphalt, and Heavy-Duty Construction

EAF steel slag aggregate is a high-density, abrasion-resistant material widely used in infrastructure and heavy construction. With low expansion characteristics, consistent gradation, and high bearing capacity, it is technically suitable for road base layers, asphalt and bituminous mixes, drainage systems, embankments, industrial yards, and railway ballast applications. International buyers source volumetrically stable, quality-graded EAF slag aggregate for heavy-duty pavements, pavement layers, and high-load areas where reliable mechanical performance and durability are required. Material is supplied in controlled size ranges and specifications to ensure compatibility with engineering and construction standards. As an exporter serving global markets, we support overseas contractors, asphalt producers, infrastructure companies, and engineering firms with specification matching, grading options, documentation, and shipment coordination, enabling dependable sourcing of EAF steel slag aggregate for construction and infrastructure projects worldwide.
