Bitumen Content

Previous pageReturn to chapter overviewNext page

This test covers the determination of bitumen content in hot-mixed paving mixtures and paving structures. In these test methods the paving mixture is extracted with a reagent. The bitumen content is then calculated by the difference from the mass of the extracted aggregate, moisture content, and mineral matter in the extract.

 

The data entry and calculations for this test are performed on the Asphalt Bitumen Content form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the reporting section below. The format of this report is controlled by the geotechnical template used for the test.

 

The methodology and calculations for this test adhere to "ASTM D 2172-01 Standard Test Method for Quantitative Extraction of Bitumen from Bituminous Paving Mixtures". For more detailed information on the methodology and calculations please review this standard.
