NONDESTRUCTIVE TESTING OF DENSITY AND MOISTURE IN HIGHWAY CONSTRUCTION

Construction control of highway embankments is usually performed by conventional testing procedures for density and moisture, such as the sand cone method. Compaction control and determination of relevant properties of asphaltic concrete are carried out by drilling core samples and evaluating the results in the laboratory. The author describes various modes and applications of density measurements and moisture measurements using nuclear gauges. These measurements may be carried out by the Direct Transmission method, where precise control to a given depth is desirable, and where minor disturbance of the material tested is not detrimental. An alternate method is the Backscatter method, which can be used on earth works, as well as on asphalt surfaces. The author discusses two test projects, one of which measured the compatibility of nuclear moisture-density gauges from different manufacturers, while the other determined the unit weight and thickness of bituminous pavement using nuclear gauges.
