Intelligent Compaction, Does It Exist?

This paper, from the proceedings of the 52nd Annual Conference of the Canadian Technical Asphalt Association (CTAA), discusses intelligent compaction. Intelligent Compaction (IC) is a system used to improve the efficiency and effectiveness when double drum vibratory rollers are used to compact an asphalt concrete mixture. The authors describes two field test sections that were constructed in order to advance the development of an IC system for the compaction of asphalt concrete mixes. They note that there are many variables that affect the ability of the compaction equipment to properly densify the mix. One of the most important variables is the temperature of the mix, which is a constantly changing mix property. In addition, the modulus, stiffness, or strength of an asphalt concrete mix measured at one temperature may not be related to the modulus, stiffness, or strength of the mix when the compaction process is finished. Their study showed that the number of roller passes over each point in the pavement surface can be monitored with GPS equipment, the surface temperature of mix can be measured, and a relative stiffness value for the mix can be determined during the compaction process. The resulting uniform application of the compaction across the width and down the length of the roadway makes a significant improvement in the consistency of the density obtained.
