A TOTAL OF 150 SURFACE MOISTURE-DENSITY TESTING SYSTEMS WERE REPORTED AS BEING IN THE POSSESSION OF 37 STATE HIGHWAY DEPARTMENTS. NINTEEN ASPHALT DENSITY PROBES ARE OPERATED BY 11 STATES WITH THE LARGEST (5) IN NEW MEXICO. ONLY 2 STATES REPORTED USING NUCLEAR PROBES FOR ASPHALT CONTENT DETERMINATION: COLORADO AND OKLAHOMA. TEN STATE HIGHWAY DEPARTMENTS HAVE A TOTAL OF 10 NUCLEAR DEPTH SYSTEMS. THREE HUNDRED SEVENTY-FOUR INDIVIDUAL PIECES OF NUCLEAR EQUIPMENT (SCALERS AND PROBES) WERE REPORTED AS BEING IN THE POSSESSION OF THE 37 DEPARTMENTS HAVING NUCLEAR EQUIPMENT. TWENTY-FOUR PER CENT OF THE STATE HIGHWAY DEPARTMENTS REPORTED USING THE SURFACE MOISTURE-DENSITY NUCLEAR EQUIPMENT FOR SPECIFICATION MATERIAL CONTROL.
