Construction-Related Asphalt Concrete Pavement Temperature Differentials and the Corresponding Density Differentials
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 what kind of problem the Washington State Department of Transportation (WSDOT) experiences with hot-mix paving, whether temperature differentials or aggregate segregation or both, the possible causes of those problems, and what WSDOT can do to fix the problem.
