Intelligent Compaction: Understanding the Technology

This EDC Exchange will focus on real world examples of where Intelligent Compaction (IC) has been used by contractors.  Local public agencies can benefit from this technology by adapting IC roller retrofit kits to existing vibratory rollers.  It gives the local public agency the opportunity to upgrade their existing fleets and take advantage of this technology.  The implementation of this technology and the availability of retrofits kits make using IC more affordable to everyone.

Compaction is one of the most important processes in roadway construction.  It is needed to achieve consolidation and uniformity of the materials, which in turn better ensures a stable base platform and pavement surface.  Construction materials possess optimum densities that ensure adequate support, stability, and strength.  Achieving uniform compaction consistently is extremely important.  Current processes using conventional compaction machines may result in inadequate and/or non-uniform material compaction, which can be one of the major factors that result in premature failure in pavements.  IC helps to overcome this.

IC refers to the compaction of road materials, such as soils, aggregate bases, or asphalt pavement materials using modern vibratory rollers equipped with an integrated measurement systems (high precision positioning systems, accelerometers, and onboard computer reporting systems) to provide feedback to the roller operator. By integrating measurement, documentation, and control systems, the use of IC rollers allow for real-time feedback to the contractor of the compaction process.  IC rollers maintain a continuous record with color-coded plots that include the number of passes, stiffness values, temperature, frequencies, amplitude, and roller speed as well as the location of the roller drum.
