Los Angeles Abrasion Machine for Aggregate Testing

The Los Angeles Abrasion Machine is designed to evaluate the resistance of aggregates to abrasion and impact in accordance with international testing standards. The test is widely used as an indicator of aggregate quality by measuring the degradation of standard aggregate gradations inside a rotating steel drum containing abrasive steel balls.

The machine features a durable electrostatic powder-coated finish and can be configured for both ASTM and EN test methods. Users can preset the required number of drum rotations, and the machine automatically stops once the selected number of revolutions has been completed.

Los Angeles Abrasion Test

The Los Angeles Abrasion Machine is developed to determine the resistance of aggregates to wear caused by abrasion and impact. During the test, aggregate samples are placed inside a rotating steel drum together with a specified number of hardened steel balls. The combined abrasion and impact action simulates the mechanical stresses experienced by aggregates during service.

Depending on the applicable standard and sample grading, up to twelve steel balls are used during testing. The test provides a reliable indication of aggregate durability and suitability for construction, pavement, and highway applications.
