Construction-related asphalt concrete pavement temperature and density differentials
KA Willoughby, JP Mahoney… - Transportation …, 2002 - journals.sagepub.com
The Washington State Department of Transportation (Washington State DOT) examined
temperature differentials in hot-mix asphalt paving over four construction seasons. From
those studies it was found that low-density areas can be caused by temperature differentials
in the mat. The study summarized is based on an examination of 17 projects during the 2000
Washington State DOT paving season to determine density differentials in the mat with a
“density profile.” A density profile is a series of density readings taken in a longitudinal …

The detrimental effects of low compaction temperatures or aggregate segregation have
been documented for at least forty years. Lower compaction temperatures are directly
related to an increase in air void content, which decreases the strength of the pavement.
Even with a perfect mix design, if the mix is not properly compacted in the field, the final
product will not last for its intended length of time. The goals of this study were to determine
