AN IMPROVED NUCLEAR DENSITY GAUGE. Period covered June 1 to July 1, 1959

In order to ensure the control degree of compaction and meet the design requirements in the process of asphalt pavement construction, reduce the core detection for the damage in the late. It using non-nuclear density gauge to test density, and carries on the comparative analysis with the density of core test data or conversion degree of compaction data, then study the variation regularity of after the calibration for field dynamic control compaction with the roller compaction times, Conclusion non-nuclear density gauge control accuracy and error causes in the asphalt layer compaction testing. Experiment results show that non-nuclear density gauge must be proper calibration, which according to different structure layer, gradation type and different materials and core calibration method test values. At the same time suggest appropriate to increase the number of calibration for 10~15 points, which reduce error and test error for choosing, make its accuracy of control within 2%. The conversion relationship between detecting the density and the water method to testing compaction were emphatically studied, this provides a basis for non-nuclear density gauge effective application in the field compaction test grade road asphalt layer.

A better knowledge of the characteristics of muddy areas, in access fairways and port basins, and of the behaviour of ships during their crossing, presents the double interest of enhancing the navigation possibilities, through a more precise adjustment of the ship draught to the status of the bottoms, and permiting a more rational organization of the maintenance dredging campaigns. Considerable savings will be obtained through the development of such knowledges for harbours management. These improvements imply the use of measuring equipments which must be handy, sturdy, reliable and which give accurate measurements. The JTD3 gauge presented by the Radioisotopes Applications Service of the French Atomic Energy Commission is an important step in the development of such measuring equipments. It is now in running order, and commercially available, after thorough test campaigns, undertaken during many months in different french harbours. New developments are already engaged, namely through the design of a turbidity gauge able to make dynamic measurements.
