Asphalt Aggregate Quality Requirements: Specifications & Testing

Aggregates make up 90-95% of asphalt pavement by weight. Understanding and meeting quality requirements is essential for producing durable, high-performance asphalt mixes.

Why Aggregate Quality Matters for Asphalt

Unlike concrete where cement provides the primary binding, asphalt relies heavily on aggregate interlock and adhesion with the binder. Aggregate shape, texture, and cleanliness directly affect mix stability, rut resistance, and durability.

Critical Quality Parameters

Gradation meeting Superpave or agency specifications
Fractured faces for stability and interlock
Flat and elongated particles affecting compaction
Los Angeles abrasion for durability
Sand equivalent and clay content
Absorption affecting binder demand

Industry Insight

Asphalt producers using AI-powered aggregate analysis report 25% reduction in quality-related production delays. Real-time gradation monitoring catches stockpile variations before they affect mix performance.

Testing Automation for Asphalt Aggregates

Modern testing automation includes image-based gradation analysis, automated LA abrasion testing, and real-time moisture monitoring—all integrated into a unified quality management system.
