THE USE OF NUCLEAR METERS TO ESTIMATE THE COMPACTION OF ASPHALT LAYERS

The feasibility of using nuclear density meters for assessing the degree of compaction of asphalt layers is discussed. A brief description of nuclear meters and their method of operation is given and the likely relative advantages of nuclear meter and core density determination are outlined. The paper describes a study to compare the effectiveness of several different meters, which indicates that similar performance can be expected from the various meters. The variation due to measurement with a nuclear meter is estimated. It is concluded that, very conservatively, equivalent accuracy to that from a number of cores can be achieved by making twice the number of measurements using a nuclear meter. Procedures are suggested for use of the meter, with any necessary calibration, for control of asphalt compaction. /Author/TRRL/
