Description

B091M 压力老化容器 (PAV)

PAV to simulates in-service oxidative aging that occurs inasphalt binders during service after 5 to 10 years (long-termaging). The sample is exposed to high pressure and temperature for20 hours (selectable to 99). The Pressure Ageing Vessel (PAV)features 100% compliance with the laboratory standards related toaging the bitumen. The unit consists of a stainless steel vertical pressure vessel (AISI 304 with ASME and CE certifications) enclosed in acabinet with encased band heaters. A source of compressed air witha pressure of at least 2.1 MPa and a pressure regulator generatesand maintains the aging condition required.


The unit is equipped with a 7" colour Touch screen controller withfront panel user interface with easy to use step-thru operation. Theuser-friendly software allows the operator to carry out the test in different modes:

• AUTOMATIC:It’s possible to select from 4 different temperatures(85, 90, 100, 110 °C) and 2 different testing time (20 or 65 hours).

• SEMI-AUTOMATIC:It’s possible to select a temperature from 60to 120 °C and run the test for 20 or 65 hours as in the automaticmode

• MANUAL:This mode can be used in research and it allows tomanually select the temperature from ambient to 130 °C and thetesting time from 1 to 99 hours.


Temperature and pressure can be monitored in real time, thanksto a platinum RTD probe and a pressure transducer. Data logs of bothtemperature, aging time and pressure are saved on USB stick at theend of the test.


A pre-heat mode allows to reach a imum of 60 °C before introducing the sample in safety conditions reducing the conditioning timeof the sample that can reach faster the test temperature. Thanks toan innovative heating system and the pre-heating mode the test canstart in around 1 hour.


The instrument is supplied complete with a sample rack for thesimultaneous testing of ten specimens, ten specimen pans as perstandards, but without compressed air source, 2.1Mpa minimumpressure.
