STANDARD: ASTM D7870
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.
