Standard Method of Test for
Asphalt Binder Content of Asphalt
Mixtures by the Nuclear Method
AASHTO Designation:T 287-06
SCOPE
1. 1. 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-thennalizationtechniques.
1.2.The values expressed in SI units are to be regarded as the standard. The inch-pound equivalents of the SI units may be approximate.
1.3.Nuclear gauge operations and maintenance are not covered in detail. See the manufacturer’s manual for details.
1.4.This test method involvespotentially hazardous materials, operations, and equipment. This
method does not purport to address all of the safetyconcerns associatedwith its use. All operators
will be trained in radiationsafetyprior to operating nuclear gauges. Some agencies require the
use ofpersonal monitoring devices such as a thermoluminescent dosimeter orfilm badge.
