Standard compaction testing
In Australia, the compaction test for soil is conducted in accordance with the Australian Standard AS 1289.5.1.1:2018. It provides detailed specifications for the compaction test equipment, compactive effort, sample preparation, and calculations to ensure consistent and accurate results. It is a widely recognised standard used by geotechnical engineers and soil testing laboratories across Australia for […]
The Importance of Achieving Soil Compaction
Introduction to Soil Compaction Soil compaction plays a vital role in ensuring the stability, durability, and overall performance of structures. Geotechnical engineers employ various techniques to densify soil and enhance its engineering properties. The required compaction percentage varies depending on the application: for example, commercial projects typically require 98% compaction, residential projects aim for 95%, […]
