Abstract:The performance of the Troxler Electronics Laboratory Model 3411 nuclear gage was evaluated through laboratory tests on the Department's density and moisture standards and field tests on various soils, base courses, and bituminous concrete overlays throughout the state. From this work five recommendations were developed and submitted to the Department. The three most significant recommendations were (1) that with the Troxler 3400 series gages, the 6-inch direct transmission mode of testing be used with the roller pattern method of compliance testing for density on base courses; (2) that the Materials Division's moisture calibration standards be assigned moisture content values of 0, 7, and 17 lb./ft.³; and (3) that the Department not purchase direct readout gages without further evaluation.
