This test method can be used for quantitative determination of asphalt content in HMA paving mixtures 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.

1. Scope

1.1 This test method covers the determination of asphalt content of hot-mix asphalt (HMA) paving mixtures and 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.
