Bureau of Public RoadsUS Transportation CollectionThe determination of in-place density by the use of nuclear moisture-density devices has proven to be an exceptionally useful tool to the modern Highway Engineer. In order to adequately adapt this new testing equipment to efficient field use, evaluation of many tests under nearly every type of field condition possible was made.The research program which began in August 1962 has evaluated one of the several portable nuclear moisture-density devices now on the market and additional units have been purchased as recommended from the results of this program. Twenty-five nuclear units are now being used by construction and laboratory personnel of the Louisiana Department of Highways. This extensive field use of nuclear moisture-density devices has enabled the Research and Development Section to re-evaluate its original operating and testing procedures for these devices
