Ⅰ. Introduction

GD-0609 Petroleum Asphalt Mass Loss Tester(thin film oven)  is designed and made as per T0609-1993 Asphalt Thin Film Heating Test in the Industry Standard JTJ052-2000 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.

The asphalt mass loss tester is suitable to determine mass loss of petroleum asphalt thin film after been heated.

GD-0609 asphalt thin film mass loss tester can also be used to determine changes of penetration, softening point and breaking point and ductility of asphalt residues after the asphalt thin film has been heated to evaluate anti-aging performance of asphalt.
