What is Intelligent Compaction?
Intelligent Compaction (IC) refers to the compaction of pavement materials, such as soils, aggregate bases, or asphalt, using modern vibratory rollers equipped with an integrated measurement system, an onboard computer reporting system, Global Positioning System (GPS) based mapping, and optional feedback control. IC rollers facilitate real-time compaction monitoring and timely adjustments to the compaction process by integrating measurement, documentation, and control systems. IC rollers also maintain a continuous record of colour-coded plots, allowing the user to view plots of the precise location of the roller, the number of roller passes, and material stiffness measurements.
Compaction is one of the most important processes in pavement construction and IC is a major aid to attain high compaction quality and uniformity, which in turn ensure long-lasting pavement performance. Current procedures using conventional compaction machines may result in inadequate and/or non-uniform material compaction, which can be one of the major factors in premature pavement failure. IC helps users overcome this issue by optimising the compaction process.
At a high level, IC systems, well implemented, can lead to:
- Enabling continuous placement of material with confidence (without waiting for traditional test results)
- Reducing the risk of rework
- Increased compaction uniformity
- Lower construction costs through cost savings
- Better documentation & pavement management
- Construction verification of design values
This increase in compaction uniformity leads to increased pavement life and reduced repair costs.
