Hot Mix Asphalt Tender Zone
Approximately 500 million tons of hot mix asphalt (HMA) are placed in the United States each year. With this large quantity of HMA, it is expected that some construction problems will occur from time to time. The jobs that experience construction problems are often widely publicized, while other jobs that don't experience problems are usually never discussed during the project nor after the project is completed. This does not minimize the importance of recognizing existing problems and solving these problems during the construction process, but it does indicate the need to keep construction problems in perspective. One problem that has been observed for years, on a small percentage of projects is tenderness of some mixtures during compaction. Tender mixtures are not stable under the roller and tend to move laterally when rolled. This lateral movement sometimes results in hair-line cracks, often referred to as checking. In the past, most tender mixes were attributed to excessive temperatures and/or over sanded mixes.
