Description / Abstract:
This procedure covers the quantitative determination of the
asphalt binder content of asphalt mixtures by testing a sample with
a nuclear gauge that utilizes neutron-thermalization
techniques.
The values expressed in SI units are to be regarded as the
standard. The inch-pound equivalents of the SI units may be
approximate.
Nuclear gauge operations and maintenance are not covered in
detail. See the manufacturer's manual for details.
This test method involves potentially hazardous materials,
operations, and equipment. This method does not purport to address
all of the safety concerns associated with its use. All operators
will be trained in radiation safety prior to operating nuclear
gauges. Some agencies require the use of personal monitoring
devices such as a thermoluminescent dosimeter or film
badge.
