Aggregate Soundness Testing | AS 1141

Aggregate soundness testing evaluates the long-term durability of rock and aggregate materials when exposed to environmental stresses such as wetting, drying, and chemical attack — conditions that can cause progressive breakdown and premature pavement or structural failure. Western Geotechnical Laboratory Services (WGLS) offers a comprehensive range of accredited soundness and durability tests conducted to Australian Standards, including Sodium Sulphate Soundness (AS 1141.24), Accelerated Soundness by Reflux (AS 1141.29), Degradation Factor for Source Rock, Coarse Aggregate, and Fine Aggregate (AS 1141.25.1, 25.2, and 25.3), and Methylene Blue Absorption Value (AS 1141.66). Together, these tests provide engineers and specifiers with a thorough picture of aggregate durability and susceptibility to clay contamination, supporting confident material selection for roads, pavements, and civil construction projects across Western Australia.
