AUTOMATIC CLOSED-LOOP SYSTEM
STANDARD: ASTM D2172 | EN 12697-1
The Asphalt Mix Analyzer (AMA) is an innovative device capable of combining all the processes associated with bitumen extraction and recovery.
The unit has been designed for the purpose of determining the bitumen content in asphalt mixture and it is the best solution to analyse and
characterize the properties of the reclaimed asphalt pavement (RAP).
Through the use of solvent selectable from perchloroethylene or trichloroethylene*, the final result of the process is the separation of aggregates
and filler from bitumen in order to verify the quality of the recovered granular materials and determine the mineral skeleton of the mixture. On
the other hand, the bitumen can be separated from the remaining solvent solution by rotary evaporation in order to make the binder available
for further analysis such as DSR, DTT and BBR according to Performance Grade and conventional bitumen tests such as penetration, ductility,
softening point among others.
Note*: The unit is supplied without the solvent that has to be purchased independently.
MAIN FEATURES
Fast analysis reducing extraction costs and time.
Combination of ultrasonic impulses and heating effect
to a complete bitumen extraction.
Complete extraction in less than 50 minutes (depending
from the material tested).
Complete close cycle avoiding toxic fumes for healthy
environment.
Automatic solvent distillation during extraction.
Integrated 7’ colour Touch screen controller.
Customizable cycle: selectable pre-wash phase, number of
washing and drying cycles.
Optional direct connection with rotary evaporation
apparatus.
Optional integrated balance for automatic determination of
the bitumen content.
The unit consists in a stainless-steel washing chamber where
the user introduces the asphalt sample up to 3.5 kg. Subsequently,
thanks to an accurate centrifugation process, the filler is separated
and collected into the centrifuge cup while the bitumen solution is
drained off to the solvent recovery chamber. Most of the solvent is
recovered by condensation and it can be used for other extractions.
The remaining part of the bitumen solution can be collected in an
extraction flask after distillation, available for further analysis.
In order to perform this cycle, the unit is equipped with a multi-layer
mash washing drum available with different openings (0.063,
0.075, and 0.090) to contain the aggregates, a centrifuge cup
to collect the recovered filler and an extraction flask to collect the
remaining bitumen solution.
Before starting washing, the unit allows to add a pre-wash phase in
order to improve the process of separation and extraction of bitumen.
TECHNICAL SPECIFICATION
– Maximum sample weight: 3.5 kg
– Centrifuge rotation speed: 8000 r.p.m.
– Scale: 10 kg, 0.1 g res.
– Cup dimensions: Ø120 mm x 200 mm height
– Extraction time: Less than 1 hour depending on the mix tested
(including drying time)
– Solvent per extraction reused for several tests
Power supply: 230V 50Hz
Dimensions: 1400x750x1500 mm approx.
Weight: 240 kg approx.
The unit presents a 7’’ colour Touch screen controller with front
panel user interface with easy to use step-thru operation. The userfriendly
software allows the operator to set up:
number and duration of the prewash cycles;
number and duration of the washing cycles;
number and duration of the drying cycles.
The asphalt mix analyzer can incorporate an optional balance into the
worktop, for an easier weighting process at each phase.
The machine automatically determines the bitumen content
through a guided procedure in accordance with the standards.
The door is locked during all test phases to provide a safe environment.
Furthermore, the test stops automatically in case of anomalies
or malfunctions, showing the type of alarm on the display in real time.
The solvent mode extraction has to be selected before supplying the
unit, and the machine will be calibrated accordingly.
