Proper testing and screening of Hot Mix Asphalt (HMA) mixes for moisture susceptibility is a crucial requirement for designing today’s high-performing, longer-lasting pavements. This product is designed to simulate HMA pavement asphalt stripping mechanisms, which are due to water and repeated traffic loading. Current moisture sensitivity tests suffer from poor repeatability and test times can take up to seven days. HMA conditioning in the instrument is automatic and can be completed in less than a day.
Plug the unit into a standard wall outlet, place the sample in the chamber, select your settings and the unit does the rest. The device creates pressure cycles within the chamber to simulate the effect of moisture on the asphalt mixture. The data from the unit can be stored and transferred to a PC for evaluation and storage.
