Summary
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.
