Asphalt Analysis

Humboldt provides a variety of Extractors, filtered and filterless, for any material testing needs.

Centrifuge Extractors are used to separate the liquids in the field of gravity inside the rotor and uses the rotation of the rotor inside a centrifuge to mix two immiscible liquids outside the rotor. It is designed for efficient and reliable quantitative determinations (weight and grade) of bitumen content in hot-mix asphalt specimens to determine constituent proportions.

Vacuum Extractors are designed to determine the bitumen content of a hot paving mixture by separating the aggregate and/or mineral matter from the mixture by means of a vacuum. The aggregate remaining after extraction of the bitumen may be used for sieve analysis.

Reflux Extractors are used to determine the percentage of bitumen in a paving mixture using hot solvent extraction.

The Asphalt Solvent Recycler is designed to recycle the solvents used in asphalt extraction tests. It successfully extracts pure solvent from the oil and wastes generated from the extraction process and generates clean solvent ready for reuse in a new test. The unit reduces the need for new solvent and eliminates problems with solvent disposal.
