| 摘要： | This report conducted a field evaluation of portable non-nuclear density gauges to determine their effectiveness and practicality for quality control and acceptance of asphalt pavement construction. It was determined that non-nuclear density gauges can be used to measure in-place asphalt pavement density if they are calibrated to nuclear density gauges and a specified number of sample test sites are used. Three portable non-nuclear gauge models were evaluated in this study, including the Trans-Tech PQI 300, Trans-Tech PQI 301, and Troxler Pave-Tracker 270lb. A CPN MC-3 nuclear density gauge was compared to the non-nuclear gauges; six-inch diameter cores were tested to ensure nuclear gauge calibration. A total of 16 individual HMA projects were used to compare the gauges and cores. Ten of the 16 projects included testing on multiple days and/or multiple mixture types. |
