LA Abrasion Machine

The Humboldt LA Abrasion Machine is designed to measure aggregate degradation resulting from abrasion, impact, attrition, and grinding inside a rotating steel drum with hardened steel charges. The test is widely used to evaluate and compare the durability of coarse aggregates intended for asphalt, concrete, base, and other construction applications.

Key Features

• Meets ASTM C131, ASTM C535, and AASHTO T 96 requirements
• Heavy structural-steel frame
• Abrasion-resistant steel drum
• Balanced drum assembly allows easier manual positioning
• Enclosed positive chain drive
• 1 hp electronically controlled motor
• Automatic overload cutoff
• Removable control panel can be remotely mounted
• Includes revolution counter, catch pan, and 12 hardened-steel abrasion balls
• 120V, 60Hz

Typical Applications

Aggregate source evaluation, coarse aggregate durability testing, DOT laboratories, asphalt producers, concrete producers, quarries, commercial testing laboratories, and universities.

Lab Manager's Tip

If the machine will be installed in an occupied laboratory rather than a separate aggregate room, consider adding a compatible sound enclosure. LA Abrasion testing generates substantial impact noise during the test cycle.
