ABSTRACT:
A testing system for determining the water sensitivity of a compacted asphalt concrete specimen under various conditions isolates the specimen on a test stand in an environmental cabinet by an impervious shroud and end platens connected to an external fluid circulating system. The specimen is loaded via a load cell by a pulsating actuator and a transducer on the specimen measures axial deformation. Data is transferred from the load cell and transducer to a micro-computer system for analysis.
