Abstract: The investigation described in this report evaluated the accuracy of four moisture meters to consistently measure fine-aggregate moisture contents and to evaluate the operational features of the instruments. No data were developed in this investigation that would indicate that any of the four commercial devices studied was superior to others or would be incapable of supplying adequate information upon which to base control of surface moisture levels of fine aggregate. The devices appear to have a level of precision of the same order as the hot plate method (CRD-C 113); there was no consistent pattern of bias.
