Asphalt PAV pressure aging tester

PAV-1 typeAsphalt PAV pressure aging testerThe purpose of using high temperature and compressed air to accelerate the aging of asphalt in a pressure vessel is to simulate the oxidative aging of asphalt during road use, and to evaluate the antioxidant aging ability of different asphalt under test temperature and pressure conditions. However, it cannot explain the influence of mixing factors or the actual use conditions of asphalt on aging.

The sample used in this method is the residue obtained from the rotary film oven test method.

Usage environment

To ensure the normal operation of the control system, the instruments must be installed on the control cabinet. The usage environment of the instruments not only affects their normal use, but also relates to them

Maintenance and measurement accuracy. The instrument usage environment should meet the following requirements:

Working environment temperature: 0-50 ℃;

Working environment humidity:<85% (no condensation);

An environment with minimal vibration and good air circulation;

An environment that is not prone to condensation and does not contain corrosive or flammable gases;

An environment without strong inductive interference and less prone to static electricity, magnetic fields, or noise interference.
