Ⅰ. Introduction

GD-0610 Asphalt/Bitumen Thin Film Oven (85 Type) is designed and made as per T0610 "Asphalt Rolling Thin Film Heating Test" in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.

This asphalt thin film oven is suitable to determine mass loss of petroleum asphalt thin film after been heated.

GD-0610 asphalt thin film oven can also be used to determine performance changes of penetration, viscosity, ductility, and breaking point of asphalt residue after the thin film has been heated to evaluate anti-aging performance of asphalt.

This thin film oven is also suitable to make determination as per ASTM D2872 Test Methods for Effect of Heat and Air on a Moving Film of Asphalt (Rolling Thin-Film Oven Test).
