3. Getting Started with Soil Compaction and CBR Testing
Soil compaction is one of the most crucial processes in construction and geotechnical engineering. It’s the method of increasing soil density (unit weight) by reducing air voids through mechanical means—leading to a stronger, more stable foundation for roads, buildings, and other infrastructure. In this post, we’ll break down what soil compaction is, why it matters, how it’s tested in the lab (as per AS1289.5.1.1-2003 ), and how it’s verified in the field. 🔍 What is Soil Compaction? · Compaction is the process of densifying soil by removing air from the voids between soil particles using mechanical force. · The goal is to improve the load-bearing capacity, shear strength and stability of soil while reducing frost damage, settlement, swelling, compressibility and permeability. · Measured quantitatively in terms of dry unit weight (...
