PURE MODA

EN 12697/1 - ASTM -D8159

​

Extraction and binder content determination of bituminous materials, especially for rubber-modified bituminous mixtures. The module MODA can be operated only with Asphalt Analyzer PURE Basic module.
The modified asphalt mixture will be separated by vibration and decantation within the vertical washing chamber. Up to 3.5 kg of bituminous mixtures can be placed into the washing drum.

Additives like Rubber and any others with a density lower than the solvent will be collected and separated by a submergible collector ring during the extraction process.

​

User selects the needed amount of washing and drying cycles. The materials will be automatically washed and separated into aggregates, mineral filler and binder under use of solvents and ultrasonic sound separation. The aggregates remain in the sieve drum.

​

Mineral filler is separated from binder and solvent in the centrifuge unit.
The mineral filler is collected in the centrifuge cup  and the binder-solvent mixture is concentrated in the recovery unit by distillation. The recovered solvent is collected in the recovery chamber. Mineral aggregates and filler are dried in the machine and are provided for weighing and the determination of the grading of the bituminous mixture. 

​

The  Pure Module is equipped with an indirect heating system, which allows a careful and safe handling of the used solvents which are recycled after each extraction.

​

Aggregates and collected rubber material within the collector ring are dried in the MODA module and will be ready for weighing and grading after the drying cycles are complete. Moda Module includes 1 set of washing drum and collector ring. Modul is installed on the base module.

 

Moda Module is connected to the base module. No additional electrical connection is required.

​

The closed system allows only nonflammable solvents to be used. The module can be configured for the operation with Trichloroethylene, Tetrachloroethylene or Methylene chloride (Dichloromethane).
