Pressure Aging Vessel,Bitumen-Testing-Equipment

The Pressure Ageing Vessel (PAV) has been developed to simulate in-service ageing of asphalt binder after 5 to 10 years. 
The binder is exposed to high pressure and temperature for 20 or 65 hours (selectable up to 99) to simulate the effect of long-term oxidative ageing. 

Aging pressure vessels
The aging pressure vessel is installed inside the box, is the basic component of the asphalt pressure aging box, the middle of the container is equipped with a line integrated distributor, the internal placement of the sample frame, the bottom is installed with a heating sleeve.
Control meter
The control instrument panel is set , on the front panel of the box, and the control instrument includes the temperature controller and the pressure control device.
Circuit elements
The circuit elements are installed inside the left side of the box, respectively, connected to the control instrument and heating, gasing and other execution elements.
Safety device
The pressure vessel is equipped with a relief valve and the safe opening pressure is 2.5MPa.
