Gilson LA Abrasion Machine, 230V/60HZ

The Los Angeles Abrasion Machine evaluates the resistance of coarse aggregate to abrasion, impact, and degradation in a rotating steel drum. During testing, a graded aggregate sample is subjected to repeated impact and abrasion from a specified charge of steel spheres, providing an important indication of aggregate toughness and durability for pavement and construction applications.

Key Features

• Designed specifically for standardized LA Abrasion testing
• Drum rotates at 30–33 RPM
• Heavy-duty steel drum construction
• Uses a specified abrasive charge of steel balls
• 230V, 60Hz, single-phase operation
• Approximately 38" W × 40" D × 46.5" H
• Estimated shipping weight approximately 1,200 lb
• Compatible with replacement LA Abrasion charge sets
• Meets ASTM C131/C131M, ASTM C535, AASHTO T 96 and AASHTO T 401 requirements.

Typical Applications: Aggregate laboratories, DOT laboratories, asphalt producers, quarries, commercial testing laboratories, universities, and contractors evaluating aggregate durability.

Lab Manager Tip: The required abrasive charge varies with the grading of the test sample, so laboratories should maintain the correct number and mass of steel spheres for the procedure being performed.
