Use of the Troxler 104 Probe and 115 Gauge for Asphalt Content Determinations
The report describes the evaluation of two commercial moisture content gages - a depth probe and a surface gage - for asphalt content determination of bituminous mixtures by neutron scattering. Two procedures were tried, one for each type of equipment. The depth probe proved to be unsuitable due to heating problems. Calibration standards were molded for the surface gage at six different asphalt contents. Linear regression equations for count ratio vs. asphalt content produced estimated errors of plus or minus 0.8 to plus or minus 1.1 percent asphalt. These values were higher than State's requirement of plus or minus 0.4 percent. (Author)
