Aggregate classification testing provides essential data on the composition and quality of materials used across road construction, pavement design, and civil engineering projects. Western Geotechnical Laboratory Services (WGLS) offers a full range of aggregate classification tests conducted to Australian Standards, including Particle Size Distribution — dry or washed (AS 1141.11.1 / WA 210.1), Material Finer than 75μm (AS 1141.12), Material Finer than 2μm (AS 1141.13), Light Particles (AS 1141.31), Weak Particles (AS 1141.32), and Coarse Aggregate Quality by Visual Comparison (AS 1141.30.1). Together, these tests allow engineers and specifiers to fully characterise aggregate materials and verify compliance with grading, contamination, and quality requirements before and during construction.
