Rainhart LA Abrasion Machine

The Rainhart LA Abrasion Machine provides a heavy-duty system for evaluating the resistance of coarse aggregate to degradation caused by abrasion, impact, and grinding. Built around a heavy steel cylinder with a counterbalanced drum, digital counter, and flexible control-panel placement, the machine is designed for routine aggregate durability testing in production and specification laboratories.

Key Features

• Meets ASTM C131, AASHTO T 96, AASHTO TP 108, and EN 1097-2 requirements as configured
• Includes 12 ASTM/AASHTO abrasion charges
• Heavy-duty steel cylinder
• Drum rotates at 31–33 rpm
• Digital revolution counter
• Counterbalanced drum simplifies loading and unloading
• Control panel can be bench- or wall-mounted
• 110V, 60Hz
• Available with or without a sound/safety enclosure
• Optional cabinet is lined with soundproofing material

Typical Applications

Aggregate abrasion testing, aggregate source qualification, DOT testing, asphalt and concrete aggregate evaluation, quarry quality control, and commercial materials testing.

Lab Manager's Tip

For laboratories running LA Abrasion tests regularly, I would strongly consider the sound-enclosure version. The test involves a rotating steel drum and steel abrasion charges, so controlling noise can make a significant difference in the laboratory environment.
