| 摘要： | The research project was broken up into 2 different parts. The first part involved evaluating the potential use of the Time Domain Reflectometry, TDR (ASTM D6780), as a non-nuclear means for determining the dry density and moisture content of granular base and subbase aggregates during quality control. Just prior to the study, Humboldt Equipment Company provided a device called the Electrical Density Gauge (EDG) that also claimed to be a non-nuclear means of determining dry density and moisture content. Both units were used on five separate field trials. The second part of the research study was to evaluate potential methods of increasing the permeability of recycled concrete aggregate (RCA), while attempting to maintain its structural integrity |
