High-Quality Asphalt Pressure Aging Vessel Manufacturers, Pricelist

The Pressure Aging Vessel (PAV) is an experimental device used to simulate the aging behavior of asphalt under heat, oxidation, and pressure during long-term use. Through this device, the aging process of asphalt can be accelerated, thereby evaluating its long-term performance.

Main features:

1. Simulate long-term aging: Simulate the aging process of asphalt on the road surface for 5-10 years through the effects of high temperature, high pressure, and oxygen.
2. Precise control: Temperature, pressure, and aging time can be precisely controlled to ensure consistency in testing conditions.
3. Efficient accelerated aging: Complete long-term aging simulation in a short period of time (usually 20 hours).
4. Safety design: Equipped with multiple safety protection devices, such as overvoltage protection, overheating protection, and automatic pressure relief function.
