PAVELAB50® automatic asphalt analyzer

The latest generation asphalt analyzer is 100% suitable for the use of methylene.

Automatic closed-system asphalt analyzer for separation and extraction of bitumen, filler and aggregates from asphalt samples by use of solvents. Binder extraction and recovery is important either for determining the binder content or to recover, using a Rotary evaporator, a representative bitumen sample used to perform other tests such as penetration, softening point, etc. Furthermore aggregates, including filler, are also separated, not disturbed by high temperatures and available for sample grading. In conclusion this method allows the complete analysis of an asphalt sample.

Operating principle:

The asphalt sample (max. 3.5 Kg) is introduced in a screening drum lined with 0.063, 0.075 or 0.090mm opening woven cloth and then placed inside a screening drum in the washing chamber. Bitumen and filler are separated from the sample by washing with solvent and ultrasonic motion. The mixture filler/bitumen/solvent is centrifuged and the filler is separated.

The aggregates and filler are dried by vacuum and the residue of solvent recovered by condensation. The remaining solution bitumen/solvent is then distilled and separated in two different tanks. Part of the solution bitumen/solvent can be drained before distillation and connected to a rotary evaporator to recover a bitumen sample for other tests. The clean distilled solvent is recycled for other extractions. The analyzer shall be connected to a suitable water cooling unit to feed the three different cooling coils of the apparatus.
