NUCLEAR TESTING CORRELATED AND APPLIED TO COMPACTION CONTROL IN COLORADO

A DESCRIPTION IS GIVEN OF THE INVESTIGATION MADE BY THE COLORADO DEPARTMENT OF HIGHWAYS INTO THE FEASIBILITY AND PRACTICALITY OF USING COMMERCIALLY AVAILABLE NUCLEAR DEVICES TO PERFORM MOISTURE AND DENSITY TESTS IN THE FIELD ON HIGHWAY CONSTRUCTION MATERIALS. THE CORRELATION FOUND BETWEEN NUCLEAR AND CONVENTIONAL METHODS IS PRESENTED ALONG WITH AN EXPLANATION OF THE EQUIPMENT AND ITS BASIC FUNCTIONS. ELECTRONIC RELIABILITY IS DISCUSSED AND DATA CONCERNING THE AMOUNT OF PERSONNEL IRRADIATION WHILE WORKING IN CLOSE CONTACT WITH EQUIPMENT CONTAINING ISOTOPES OF CESIUM AND RADIUM-BERYLLIUM ARE GIVEN. THE USE OF A NUCLEAR DEVICE TO CONTROL THE COMPACTION OF EMBANKMENT MATERIAL ON A LARGE PROJECT IN WESTERN COLORADO IS DESCRIBED AND ACCEPTANCE OF THIS NEW CONCEPT OF TESTING BY FIELD PERSONNEL IS RELATED. PRELIMINARY INFORMATION CONCERNING AN ATTEMPT TO CORRELATE THREE DIFFERENT NUCLEAR DEVICES WITH THE CONVENTIONAL METHOD OF DETERMINING THE DENSITY OF ASPHALTIC CONCRETE SURFACE COURSES IS ALSO PRESENTED. /AUTHOR/
