(Test Method)Standard Test Method for Asphalt Content of Asphalt Mixture by Ignition Method
Standard Test Method for Asphalt Content of Asphalt Mixture by Ignition Method
SIGNIFICANCE AND USE
4.1 This test method can be used for quantitative determination of asphalt content in asphalt mixture and pavement samples for quality control, specification acceptance, and mixture evaluation studies. This test method does not require the use of solvents. Aggregate obtained by this test method may be used for gradation analysis according to Test Method D5444.
SCOPE
1.1 This test method covers the determination of asphalt content of asphalt mixture and asphalt pavement samples by removing the asphalt cement in an ignition furnace. The means of sample heating may be the convection method or direct irradiation method.
Note 1: Aggregate obtained by this test method may be used for sieve analysis. Particle size degradation may occur with some aggregates.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitation prior to use.

3. Summary of Test Methods
3.1 The asphalt cement in the paving mixture is ignited using the furnace equipment applicable to the particular method. The
asphalt content is calculated by difference from the mass of the residual aggregate and moisture content. The asphalt content is
expressed as mass percent of moisture-free mixtures. Test Method A is intended for furnaces with an internal, automated weighing
system. Test Method B is intended for furnaces without an internal weighing system.
