Use of Accelerated Loading Equipment for Determination of Long Term Moisture Susceptibility of Hot Mix Asphalt

Stripping or moisture induced damage of hot mix asphalt (HMA) pavements can be caused by different factors. Some factors are related to compatibility between asphalt binder and aggregates, while others are related to moisture and drainage conditions inside the pavement. Moisture induced damage of HMA has been a persistent problem in some areas of the Logan International Airport in Boston, MA. In many cases, failed areas in runways and taxiways need repeated repairs. In the past, Massachusetts Port Authority (Massport) has tried to solve this problem by specifying a higher retained strength/tensile strength ratio (TSR) from moisture susceptibility tests on HMA. However, mixes with specific types of aggregates, even though meeting the increased TSR requirements, have continued to show failures. In response to this situation, Massport has initiated a study to (1) ascertain whether there is a need to conduct an accelerated loading test to determine long term moisture susceptibility for identifying poor performing materials, (2) to determine if multiple cycles instead of the current one cycle should be used, and (3) determine whether lime should be used regularly for HMA airport pavements.
