I. introduction
1) DSHD-0610 Asphalt Rolling Thin Film Oven is designed and developed as per T0610 "Asphalt Rolling Thin Film Oven Test" in the Industry Standard of People's Republic of China JTJ052 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering.
2) DSHD-0610 Asphalt Rolling Thin Film Oven is applied to determine mass loss of highway asphalt rolling thin film after heating, and the change of penetration, viscosity, ductility and breaking point of asphalt residue after the thin film has been heated, in order to evaluate the aging performance of asphalt.
3) DSHD-0610 Asphalt Rolling Thin Film Oven is also suitable to make test as per ASTM D2872 "Test Methods for Effect of Heat and Air on a Moving Film of Asphalt (Rolling Thin Film Oven Test) ".
