STATE SURVEY OF PROCEDURES AND SPECIFICATIONS FOR THE USE OF NUCLEAR GAUGES

Data is analyzed that was generated in a questionnaire survey of users (in the 50 state highway agencies, Canada, cities, and counties) of nuclear moisture-density gauges. This report presents information from the states related to technical aspects which include: basic gauge calibration (density, moisture), operational checks, safety, training of personnel, repair facilities, gauge seating, test count, density test configuration and materials tested. The utilization of density test results to determine compliance with specifications is done in a variety of ways ranging from reliance upon the results of a single test to a semi-statistical utilization of moving averages or control test strips. The materials tested include: bituminous surfacing, granular base and subgrade. The data analysis does not reveal any large differences among the replies. The numerous procedural options available make it possible to tailor the use of nuclear gauges to a wide range of applications.
