Understanding how aggregate materials perform under load is critical to the long-term durability of road pavements, base courses, and structural fills. Western Geotechnical Laboratory Services (WGLS) delivers accredited aggregate strength testing to both Australian Standards and Western Australian specifications, including Aggregate Crushing Value (AS 1141.21), Wet/Dry Strength Variation (AS 1141.22), and Crushing Test Value (WA 223.1). These tests quantify the resistance of aggregate to mechanical breakdown under compressive stress and moisture exposure, providing engineers and materials specifiers with the data needed to select and verify aggregate for high-performance pavement applications across Western Australia.
