Hylec Controls has introduced a new fully automatic machine designed to safely and accurately analyse asphalt mixtures in a laboratory environment.

Presenting an alternative to the use of a furnace to determine the amount of binder and aggregate in an asphalt mixture, Hylec’s new asphalt analyser employs solvent extraction to separate the two components from the bitumen, and uses distillation to recover the solvent.

The new asphalt analyser offers several benefits: Operating under a vacuum, the machine does not release any solvent fumes into the lab, instead using a vent that can be connected externally or to an activated carbon filter. Since the aggregate and binder samples are fully dried, there is no requirement for drying in an oven later, which can cause problems with the solvent escaping into the lab.

Hylec’s asphalt analysers operate at low temperatures so that the binder weight does not decrease, as it otherwise would in the furnace method.
