Moisture Induced Stress Tester - The M.i.S.T™ - AASHTO TP 140
Moisture Induced Stress Tester - The M.i.S.T™
The InstroTek, Inc. M.i.S.T. ™ is a cyclic conditioning system that is designed to simulate the stripping mechanisms that occur in H.M.A pavement layers. The M.i.S.T ™is a stand alone unit that consists of a pressurized chamber that pushes and pulls water through a compacted asphalt sample, simulating the action of an automobile tire on the road. The tests can be performed at different pressures and temperatures to replicate different traffic and environmental conditions. The unit is completely automatic and results are ready in as little as four hours. Simply place your asphalt core sample in the M.i.S.T ™ testing chamber, select your test parameters, press start and the unit does the rest.
