Aggregate Abrasion Testing | AS 1141 | WGLS Perth
(50 characters)
📝 Introductory Paragraph
The resistance of aggregate to surface wear and polishing is a critical performance characteristic for materials used in road surfacing, asphalt, and high-traffic pavement applications. Western Geotechnical Laboratory Services (WGLS) provides accredited aggregate abrasion and wear testing to Australian Standards and Main Roads WA specifications, covering Los Angeles Abrasion (AS 1141.23), Los Angeles Abrasion for Limestone (WA 220.2), Resistance to Wear by Attrition (AS 1141.27), and Polished Aggregate Friction Value (AS 1141.40/42). These tests assess how aggregate materials degrade under mechanical wear and repeated trafficking, giving pavement designers and materials engineers the data required to select aggregates that will maintain structural integrity and surface skid resistance over the life of the pavement.
