Accelerated Implementation of Intelligent Compaction Technology for Embankment Subgrade Soils, Aggregate Base, and Asphalt Pavement Materials

Abstract

Intelligent compaction (IC) is an emerging technology, and for some applications it is mature enough for implementation in field compaction of pavement materials. The intent of this project is to realize the blueprint in the FHWA IC strategic plan. This study was under the Transportation Pooled Fund project, TPF-5(128), which includes 12 participating state departments of transportation: Georgia, Indiana, Kansas, Maryland, Minnesota, Mississippi, New York, North Dakota, Pennsylvania, Texas, Virginia, and Wisconsin. IC is a compaction technology used for materials including soils, aggregates, and asphalt mixtures, by using vibratory rollers equipped with the real-time kinematic (RTK) Global Positioning System (GPS), roller-integrated measurement system (normally accelerometer-based), feedback controls, and onboard real-time display of all IC measurements. IC technology can be used to produce uniformly compacted pavement products that perform better and last longer.
