Bitumen Pressure Ageing System

This system is designed and made as per industrial standards T 0630-2011 Accelerated Aging Test for Bitumen by Pressure Aging Vessel in JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering and SH/T 0774-2005 Standard practice for accelerated aging of asphalt binder using a pressurized aging vessel (PAV). It also refers to standards ASTM D6521 and AASHTO PPI. It covers the accelerated aging (oxidation) of asphalt binders by means of pressurized air and elevated temperature.

Main technical features

1. The HW-PAV-1-1 asphalt pressure aging tank integrates the pressure vessel device and the optimized configuration of the automatic operating system, and uses computer real-time monitoring to ensure the correct operation of the equipment.

2. This system uses high temperature and compressed air to accelerate the aging of asphalt in a pressure vessel, simulating the oxidative aging of asphalt during road use, and is suitable for evaluating the anti-oxidative aging ability of different asphalts under test temperature and pressure conditions.
