The implementation of Intelligent Compaction (IC) in the construction of transportation infrastructure as a tool for quality control of compacted geomaterials has attracted the attention of a number of highway agencies. Compaction quality has been conventionally assessed using density, and to a less extent, modulus-based spot measurements at selected locations along the roadway section. While spot measurements do not provide a thorough rendition of the level of compaction of the roadway, IC technology is effective in meeting full coverage requirements. IC roller measurements are accelerometer-based measurements recording machine-ground interaction assumed to be indicative of the stiffness of the compacted geomaterial. …

For national economy, it is very important to have a reliable infrastructure. Because of this, all over the world, new roads are constantly being built and old roads are being maintained and, if necessary, expanded and/or repaired. Building a good quality road is very expensive, it costs several million dollars per kilometer. It is therefore crucial to make sure that the newly built and newly repaired roads are sufficiently stiff - so that they can withstand the predicted volume of traffic for a sufficient number of years. Current methods of estimating the stiffness are time-consuming and labor-consuming. The most accurate …

The nuclear density gauge (NDG) is the current tool for field compaction quality control (QC) and quality assurance (QA) for soil and base layers in the state of Texas. The Texas Department of Transportation (TxDOT) uses this nondestructive testing (NDT) device to determine the compacted density and moisture content of earthwork and unbound aggregates. However, to provide the missing link between design and quality management parameters, an alternative stiffness-based approach would be more desirable. Intelligent Compaction (IC) is defined as continuous assessment of mechanistic soil properties (stiffness, modulus) through roller parameters (frequency, amplitude and speed) integrated with global positioning system …
