Aggregate testing is the foundation of quality assurance in road construction, pavement engineering, and civil infrastructure across Western Australia. Western Geotechnical Laboratory Services (WGLS) provides a comprehensive suite of accredited aggregate laboratory testing conducted to Australian Standards (AS 1141) and Main Roads Western Australia (MRWA) specifications. Our aggregate test capabilities span the full range of material assessment — from classification and particle size distribution, shape and flakiness, density and water absorption, through to strength, reactivity, organic impurities, and surface chemistry. Whether you’re specifying materials for a major highway project, verifying quarry output, or assessing aggregate suitability for concrete or asphalt production, WGLS delivers accurate, reliable results with fast turnaround from our NATA-accredited laboratory in Welshpool, Perth.
