Pressure Ageing Vessel (PAV)
Pressure Ageing Vessel (PAV) - Bituminous binder (bitumen) analysis equipment
Asphalt binder, when exposed for years to oxygen, temperature, and traffic, undergoes a process of oxidation and hardening known as aging. This process can reduce its flexibility and increase its tendency to crack, which affects the pavement’s service life.
Analizar a largo plazo el betún y simular el envejecimiento de la mezcla asfáltica después de 5 o 10 años, mediante equipos como el Pressure Ageing Vessel (PAV), es esencial para anticipar cómo cambiarán las propiedades del ligante bituminoso a lo largo del tiempo y bajo condiciones reales de servicio.

Pressure Ageing Vessel (PAV)
The Pressure Aging Vessel (PAV) is a critical piece of equipment for long-term bitumen aging analysis, simulating the conditions an asphalt mix faces after 5 to 10 years of in-service life. This analysis is essential for predicting the performance of the bituminous binder under prolonged exposure to oxidation, temperature, and traffic loading.
