A Centrifugal Asphalt Mixture Extractor is a laboratory machine used to determine the bitumen (asphalt) content in asphalt mixtures. It works by spinning the sample at high speed while a solvent dissolves and removes the bitumen, leaving only the aggregate (stones and sand). The remaining aggregate is then weighed to calculate the percentage of bitumen in the mix.
What it is used for
Measuring the asphalt (bitumen) content in hot mix asphalt.
Quality control in road construction.
Testing whether an asphalt mix meets project specifications.
Research and laboratory analysis.
