Aggregate Toughness & Los Angeles Abrasion Machine Testing Apparatus for Civil & Geotechnical Applications
The Los Angeles Abrasion Machine is a reliable and industry-standard testing device used to evaluate the abrasion resistance and toughness of coarse aggregates. Designed in compliance with international standards such as ASTM C131, EN 12697-17, and EN 12697-43, this robust machine helps ensure that aggregates used in road construction, pavements, and other civil engineering applications are durable and capable of withstanding mechanical wear.
Key Features of the Los Angeles Abrasion Machine
Heavy-Duty Steel Construction: Built from a robust steel frame with a 711 mm inner diameter and 508 mm inner length drum, ensuring stability and long-term performance.
Rotating Drum: The abrasion drum rotates at a standard speed of 30–33 rpm, delivering consistent and repeatable test results.
Digital Revolution Counter: Equipped with a digital counter to automatically track and stop the machine after the preset number of revolutions.
Safety-First Design: Full-length opening with protective cover helps reduce noise and improves operator safety during testing.
Reliable Drive System: Powered by a 1 HP motor with a magnetic starter, overload protection, and easy-to-use push-button controls.
Adjustable Frame & Controls: Built-in auto shut-off, push-button reset, and easy adjustment functions for simplified operation.
Applications of the Los Angeles Abrasion Test
Road Construction: Evaluates the hardness and resistance of aggregates used in asphalt and concrete pavement layers.
Civil Engineering Projects: Used for quality control of coarse aggregates in bridges, highways, foundations, and other infrastructure.
Laboratory Testing: Common in geotechnical, highway, and construction materials labs to test aggregates before use in design.
Durability Studies: Helps determine aggregate toughness for use in high-traffic or high-load conditions.
