  • With 4000 Asphalt Analyzer units in operation worldwide, infraTest has engineered a truly valuable solution to safely and easily extract binder, get clean and dry aggregate, fines and rubber particles ready for sieve analysis within 45-55 minutes, all in a closed solvent based system.                                                        


    infraTest’s Asphalt Analyzer is used for the extraction and determination of binder content including for rubber modified bituminous mixtures for use with non-flammable solvents like trichloroethylene. The extraction and distillation is PC controlled with every step of the process shown on the touch panel screen. The new PG model is equipped with a second solvent circuit allowing for the extraction of asphalt mixtures as a stand-alone procedure within the washing chamber or within the vertical standing unit with an automatic decantation system where bituminous material will be separated through a process of continuous mixing. The separated rubber particles swim up to the surface where they are collected inside a special collection tray. The aggregates are stored in the washing chamber; fines are separated in the centrifuge compartment.  Binder is collected in the binder recovery chamber and solvent is distilled with only 25ml permanently lost per extraction. All parts of the bituminous mixture are dried during the test procedure and ready for further testing.
