Abstract:Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent
compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase
compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and
an extended service life. This report examines IC technology, how IC quality control and assurance
specifications can encourage IC adoption, knowledge and use of IC through survey responses, and
benefits and costs of IC. The surveys reveal that a majority of respondents from state departments of
transportation have conducted IC demonstration projects, but questions about cost and willingness of
policymakers to adopt IC remain a barrier to implementation. The benefit-cost analysis demonstrates that
use of IC reduces compaction costs by as much as 54% and results in a $15,385 annual savings per lane
mile throughout the roadway’s life.
