· Rapid Cooldown Means Shorter Road Closures. Although hot mix asphalt is placed at high temperatures, usually over 300 degrees Fahrenheit, it also cools down quickly, providing stability to the pavement mixture. Thanks to its rapid cooldown period, road closures don't have to last as long – saving time and reducing traffic slowdowns.

 · Abstract This paper answers whether existing intelligent compaction (IC) technology can be used in a practical way to improve the quality control (QC) process for hot-mix asphalt (HMA) paving projects. Specifically, the paper investigates the use and the benefits of IC technology for tandem drum vibratory rollers used to construct HMA materials.

Adequate compaction of asphalt pavements during their construction is essential to the long-term performance of the pavement. Current quality control techniques determine the quality at a limited number of points and are not indicative of the overall quality of the pavement. In this paper, the intelligent asphalt compaction analyzer (IACA) is used to estimate the …
